Creatine for Alzheimer's — let's separate the hype from the hope. A new study has caused a stir in June 2025, but lead researcher Matthew K. Taylor told us: “ I don't think I can recommend it to a patient that this is going to ultimately have some sort of cognitive influence.” We speak to Dr. Taylor and Dr. Russell Swerdlow in this episode, discussing: • Role of creatine in your brain, and why it matters for energy metabolism • What the 2025 study found (and why it wasn't designed to prove effectiveness) • How scientific nuance gets lost in supplement hype • Why even promising early data must be handled with care • The vital difference between hype and hope Dr. Russell Swerdlow, MD is Director of the University of Kansas Alzheimer's Disease Research Center.

The Empowered Eating Pep Talk

In this episode we're diving into all things protein recommendations for women, especially women over 40. The spoiler alert is this: RDAs are not in your best health's interest. In case you've slept through this, check out the latest episode of Dr Gabrielle Lyons with Donald Layman. It's a long hike or two walks to be sure. But in it you'll hear how nutritional guidelines came about. It will make you laugh. We have put so much stock in something that was basically, like, this sounds good or a compromise. And… the recommendations as we well know originally came from the dairy, beef and wheat councils who have government connections. Much of what you've been led to believe about animal protein and saturated fat is false. Much of what you believe about eating cholesterol causing cholesterol is false. But what you haven't heard about protein is also keeping you from optimal health. The only way to know for sure how you're affected is to: measure your body composition and skeletal muscle mass. Measure fat in a percentage and measure muscle in absolute lbs or kg. Log your energy, sleep, and hormone levels. Get the protein support you need with Flipping Fifty's protein powders.

That said, the hope is that it gives you reason to question and challenge the information presented to you or previous beliefs about nutrition, energy, food impact on health and performance. Key Guidelines on Protein Recommendations for Women: Based on the International Society of Sports Nutrition (ISSN) for healthy, exercising individuals. Muscle Protein Synthesis (MPS): Both resistance exercise and protein intake boost MPS. Consuming protein before or after resistance exercise enhances this effect. Daily Protein Intake: For muscle building and maintenance: 1.4–2.0 grams of protein, per kg body weight, per day (g/kg/d) Example: 130 lb (59 kg) female would need 118 g of protein per day at 2.0 g/kg. For improved body composition (in resistance-trained individuals): 3.0 g/kg/day may help reduce fat mass. Example: 130 lb (59 kg) female would need 177 g of protein per day at 3.0 g/kg. Per-Serving Protein Intake:Recommendations vary by age and exercise routine. Generally, 0.25 g of high-quality protein per kg of body weight, or 20–40 g per serving, is ideal. Leucine Content: Effective protein doses should contain 700–3000 mg of leucine and a full range of essential amino acids (EAAs). Leucine content in proteins: Pea protein: 1.7 g Hydrolyzed beef (Paleo): 2–3 g High proportions of essential amino acids (EAAs) and adequate leucine, are most effective in stimulating MPS. Protein Distribution and Timing: Ideally, protein intake is evenly distributed every 3–4 hours throughout the day. However, the anabolic effect of exercise is long-lasting, at least 24 h. Continuing protein intake throughout this period is beneficial to reduce muscle breakdown Animal vs. Plant Proteins: Animal proteins provide all EAAs at high levels. Most plant proteins need to be combined to meet EAA requirements, except for hemp hearts, quinoa, and (if tolerated) soy products. Carbohydrate and Protein Recommendations for Women Endurance Athletes: Ensure adequate carbohydrate intake to enhance performance. Adding protein can reduce muscle damage and aid recovery. Pre & Post Menopausal Women: Protein Timing: Recent studies on men suggest timing is less important, but menopausal women benefit from more immediate post-exercise protein (40–60 g) to combat anabolic resistance. Carbohydrate Needs: Low Energy Availability (LEA) and Relative Energy Deficiency in Sport (RED-S) risks increase when energy intake is too low: Women: ~30–35 calories per kg of fat-free mass (FFM). Men: ~15 calories per kg FFM. Example: With 100 lbs FFM, a woman needs ~340 g of carbs/day. Risks of Low Carbohydrate Intake: Many women consume only 50, 100, or 150 g of carbs, which may lead to not just reduced performance but also endocrine dysfunction and low bone mass. Your Go-To Action Plan on Protein Recommendations for Women in Midlife Assess Current Intake: Track total calories and protein. Pre- and Post-Workout Nutrition: Focus on nutrient intake before and after high-intensity strength and interval training. Evaluate Progress: Monitor weight, body composition (body fat and skeletal muscle). Identify Caloric Needs: Check if you are undereating to maintain weight—especially if it has been ongoing. Prioritize Lean Muscle Gain: Eating more and building muscle may be necessary before metabolism supports fat loss. Protein Strategy for Postmenopausal Women: Aim for 1 g protein per lb of body weight. Distribute evenly at meals, targeting 30 g minimum, with 40+ g at meals and post-exercise. Track Results: Regularly evaluate the impact on body composition and overall health.

When it comes to protein consumption in menopause, there are several things to consider. Even though there's no science or medical evidence to show higher (than you grew up with or are used to) protein intakes cause kidney (renal) issues, many people still believe it's true. What is true is or anyone who has an existing renal issue, diabetes for instance, high protein diets should be discussed with and then monitored with your physician. Let's back pedal to what is “high protein.” It's very personal in interpretation. The recommended range of protein is 10-35A% of total calories. That's a large range. So, if you eat 2500 calories a day and consumed only 10% protein that would be 250 calories from protein. Protein contains 4 kcal per gram so that's 62 grams of protein. If you ate 35% of your diet from protein, you'd consume 875 kcals from protein. That would be 218 grams of protein. Anywhere between 62 and 218 grams of protein is within recommended daily amounts. That's nuts! RDAs are actually the “minimum to prevent deficiency.” Consider the meaning of that. Protein Consumption in Menopause The current recommended dietary allowance (RDA) to prevent deficiency in minimally active adults is 0.8 grams (g) of protein per kilogram (kg) of body weight. However, newer research suggests individuals trying to build muscle need more than this. It also makes sense that women over 50 with greater anabolic resistance trying to build muscle mass and lose fat will want to pay special attention to their need for protein. Consuming less protein than the body needs has been linked to decreased muscle mass. In contrast, increased protein intakes above the RDA may help increase strength and lean body mass when paired with resistance exercise. In order to build muscle, a person must consume more protein than what is broken down. This is often referred to as a net positive nitrogen balance, as protein is high in nitrogen. That is muscle protein synthesis must be greater than muscle protein breakdown for nitrogen balance to be achieved. According to the 2020-2025 Dietary Guidelines for Americans, most healthy adults over 19 years old should get between 10-35% of their daily calories from protein. One gram of protein provides 4 calories. This means that a person who eats 2,000 calories per day would need to consume between 50 and 175 grams of protein per day. Doctors generally agree that healthy adults can safely tolerate a long-term protein intake of up to 2 g per kg of body weight per day without any side effects. However, some groups of people, such as healthy, well-trained athletes, may tolerate up to 3.5 g per kg of body weight. A 130 lb individual = 60 kg 2g per kg = 120g protein 3.5g/kg = 210g protein Varied Protein Consumption Recommendations Exist The World Health Organization in their official report on protein stated that "the most widely quoted potential problems of a high-protein diet relate to renal function and damage, but as discussed [above] the evidence for such claims in otherwise healthy individuals does not stand up to scrutiny." From Stanford Lifestyle Medicine Longevity: For adults aged 50+, we recommend consuming 1.2 – 1.6 grams of protein/kg of body weight per day (0.54 – 0.72 grams/pound body weight per day). For a 165-pound adult, this translates to roughly 90 – 120 grams of protein per day To build muscle past the age of 50, we need to eat enough protein AND do weight training and consume 30 – 35 grams of protein within two hours of the workout. Due to anabolic resistance, which increases as we age, it's recommended to increase protein intake per meal to roughly 30 – 35 grams. For those over 65, another study recommended 1.2 – 2.0 grams / kg of body weight per day. Data from the Health, Aging and Body Composition study support these findings, showing that intake of animal protein (with greater content of EAA), but not plant protein, was significantly associated with the preservation of lean body mass over three years in older adults. In dieting older adults (eating significantly below adequate caloric intake need) the loss of muscle percent was much greater in studies than in those adults consuming twice the recommended daily amount. Subjects with the highest protein intake had 40% less muscle loss than those with lowest protein intake. Muscle Mass, Body Composition and Protein Consumption in Menopause When the energy content of the protein source is accounted for, the caloric intake needed to meet the EAA requirements from plant sources of protein is considerably higher than the caloric intake from animal sources of protein. This is important to consider since obesity, especially with aging, is a major public health concern. Obesity is the most predominant factor limiting mobility in the elderly For anabolic response maximal anabolic response is ~35 g/meal For older adults it is 2x that of younger adults The amount of total intake (with at least 35 g per meal) but not the pattern of intake matters most. So, you could do a large protein intake at breakfast and dinner and moderate at lunch during the day. Or you could do a simple shake pre-workout followed by a high protein meal post workout and 2 additional meals For synthesis: 35g + at meals Weight training (with adequate rest between sessions) Movement/physical activity Sleep Optimal stress levels After just 5 days of bedrest older adults have reduced sensitivity to EAAs and greater muscle breakdown compared to young adults. Any illness or injury resulting in decreased muscle function, to be followed by decreased lean muscle mass and strength. There is a significant reduced effect of EAA synthesis with age. To maximize muscle protein accretion with resistance exercise, daily protein intakes should be approximately .7-1g per lb body weight and 35g or more per meal. To promote lean body mass retention during weight loss, protein intakes of ~2.3–3.1 g/kg/day have been advocated. The human body is capable of digesting large quantities of dietary protein. Protein Consumption in Menopause and Anabolic Resistance (H2) Reductions in LBM are primarily driven by reductions in postabsorptive rates of MPS and a reduced sensitivity to the presence of a protein bolus. To effectively prevent these declines in MPS during both postabsorptive and postprandial periods, daily protein intake have been recommended to be increased to ~2.3–3.1 g/kg/day, and leaner athletes may wish to aim for intakes at the higher end of this range. 130 lb = 60 kg 2.3 g/kg = 138 g/day 3.1 g/kg = 186 g/day Anabolic resistance in postmenopausal women There is no sex difference in basal or fed muscle protein metabolism in the young, but postmenopausal women have a greater anabolic resistance than older men. Anabolic resistance is also shown by the decreased phosphorylation in the PKB-mTOR-eIF4BP1 pathway in response to increased EAA. Peri and post-menopausal women are increasingly resistant to muscle protein anabolism due to a lack of response to exercise and amino acid uptake (due to the change in the ratio of estrogen:progesterone and sensitivity of receptor sites). Research also shows that with age, we also need more protein for the same training adaptations. Current recommended dietary allowance for protein (0.8 g/kg/day) might be inadequate for maintaining muscle health in older adults, probably as a consequence of “anabolic resistance” in aged muscle. In a report using data from 1,081 adults aged 55–85 years old, more frequent consumption of meals containing 30–45 g protein resulted in the greatest association with leg lean mass and strength. Total body strength, but particularly lower body strength is closely correlated with longevity or mortality rate. Consumption of higher protein diets does not have detrimental effects on health, including kidney function, bone health, or liver function and blood lipids according to multiple sources of research. Summary of Protein Consumption in Menopause  (H2) Women in the menopause transition should target the higher end of that range (2.2 to 2.4 grams per kilogram), aiming for the lower end on easier days and the higher end on very heavy training days. Research also indicates that when undergoing a calorie deficit, higher levels of protein intake help you keep your lean mass and lose body fat. That is, set your protein intake, and then if dieting or attempting to lose weight, create a reasonable deficit in calories but with increased protein beyond normal intake. As you reach peri and postmenopause, your anabolic resistance increases, so you want to aim to have that post-exercise protein closer to 40 grams. A protein intake of 1.0–1.2 g/kg/day has been recommended for the preservation of healthy aging muscles, while 1.2–1.5 g/kg/day of protein may be necessary in older patients with acute or chronic diseases. Elderly people with severe illness or malnutrition may need as much as 2.0 g/kg/day of protein. Very active and athletes have always been advised to consume additional protein. For midlife and older women, there's even more reason to adhere to this advice. To overcome anabolic resistance, active and menopausal women's Daily protein intake should fall within the mid- to upper ranges of current sport nutrition guidelines (1.4-2.2 g·kg-1·day-1). If you are an active woman, exercising intentionally 4 or more times a week these numbers apply to you. Using 2.2 g/kg/day is the equivalent of 1 g protein to a lb of body weight. (J Int Soc Sports Nutr. 2023 Dec) Athletes [and let's include, the very active] aiming to reduce fat mass and preserve FFM should consume protein intakes in the range of ∼1.8 - 2.7 g kg(-1) d(-1) (or ∼2.3-3.1 g kg(-1) FFM) in combination with a moderate energy deficit (-500 kcal) and the performance of some form of resistance exercise.

Many women want to lose weight. To lose weight for active women over 40, they also don't want performance to deteriorate. There are a few things to consider. First, it's not the eat less, exercise more dogma that will get you what you really want.  Most women want energy, tone and definition, and strength for now and later. Better blood sugar control that supports reductions in belly fat and overall insulin sensitivity.  Am I right? But eating less and exercising more - if successful at all during menopause and post - will generally cause the opposite. Less energy, worse mood, poor sleep, less muscle tone, and spirals down from there with long term ramifications to health.  Being active, whether sports performance level or just athletic active, requires energy. There is still a way to juggle goals of maintaining or improving performance while still dropping a few pounds of extra cushioning.  Eating to Lose Weight Active Over 40 Close to the beginning and/or after completion of exercise, peri- and postmenopausal athletes should aim for a bolus of high EAA-containing (~10 g) intact protein sources or supplements to overcome anabolic resistance. Anabolic resistance is the status of muscle loss being more likely than muscle gain and it requires more intense exercise stimulus (strength training), quality protein stimulus, and recovery to overcome it.  An ACSM review of literature stated 20 g protein pre-exercise (and 40 after) for older adults to boost Muscle Protein Synthesis similar to that of a 20 yr old when workout conditions were comparable.  Time pre-exercise fuel for optimal digestion. Within 30 minutes of a workout the easier to digest fuel must be. It's not only a comfort factor, but also the diverted energy for digestion competing with the need for blood flow to deliver oxygen to working muscles. Both digestion and performance will suffer. A “simple shake” with protein powder and unsweetened almond milk or water may be the easy way to go.  If you want carbs, add a half a banana to the shake or have half cup oatmeal with protein powder. Pre-workout, avoid fiber and fat. A mixed meal eaten pre-workout should allow at least 2 ½ - 3 hours to be fully digested. Some will feel most comfortable if this is longer than that (4 hours) if it's following recommendations for high fiber, high protein and high fat.  Given recommendations range from at least 10 to 20 grams of protein pre-workout, below are some examples of protein sources. The more challenged you are with gaining lean muscle (and or are attempting to lose weight while retaining muscle) the higher end of the range you want to be. Lose Weight for Active Women: Women's Guide to Exercise Nutrition High EAA examples of 10 g protein:  Small half a simple shake including protein powder and unsweetened almond milk  Dairy (which does by the way include whey protein) generally pre-exercise wouldn't be recommended due to its influence in mucus production, even if you tolerate which a lot of women don't later in life (but Greek yogurt or cottage cheese are sources of protein- again I don't recommend pre-exercise). ·      2 eggs equal 12 grams of protein (if you tolerate eggs)  ·      ½ cup steel cut oats with protein stirred in ·      Quinoa  Choices vary as to whether you want carbohydrate prior or not to avoid early fatigue during exercise sessions. Overcoming Anabolic Resistance:  A study in the European Journal of Sports Science found higher protein intakes (2-3 times the protein Recommended Dietary Allowance (RDA) of 0.8 g/kg/d) during periods of energy restriction can enhance fat-free mass (FFM) preservation, particularly when combined with exercise. Athletes [and let's include, the very active] aiming to reduce fat mass and preserve FFM should consume protein intakes in the range of ∼1.8-2.7 g kg(-1) d(-1) (or ∼2.3-3.1 g kg(-1) FFM) in combination with a moderate energy deficit (-500 kcal) and the performance of some form of resistance exercise.  What does that look like for you?  Say you weigh 130lbs. Rounding Kgs up to 60.  Based on body weight: 162 g protein  Using the FFM example:  Say you weigh 130lbs and are 25% body fat. Subtracting the fat weight in lbs (32.5) from bodyweight leaves 97.5 Fat Free Mass.  224 g  Using the high range number for each of body weight and FFM-based protein recommendations, the daily protein recommendation then would be 162 – 224 grams of protein daily. That is with the goal of losing weight while resistance training with a moderate calorie deficit.  Taking a median number of 180 g protein with each gram of protein offering 4 kcals means you'd be taking in 720 kcals/day from protein.  Fat = 7 kcals, Carb = 4 kcals.  Prepare to be confused.  Health Organizations Weigh in (Not necessarily on losing weight) Prestigious Organizations Offer These Calculations for a 130lb active woman:  American Dietetic Association (ADA): at least 59 - 106 grams/day. The Centers for Disease Control and Prevention (CDC): 48 - 169 grams/day (10-35% of daily caloric intake). World Health Organization safe lower limit: 49 grams/day. Keep in mind these recommendations vary in goal. The least amount of protein to avoid death or illness is not the same to thrive and add lean muscle, strength and energy. We have a gap.  So, it is of course confusing. We also have emotional relationships to food and beliefs we've held for a long time. Those too are likely factors in your reaction to this episode. You're nodding or shaking. Even though the science is the basis of the content, we don't as humans adopt it readily.  Say You Don't Want to Lose Weight You Want to Maintain Daily protein intake should fall within the mid- to upper ranges of current sport nutrition guidelines (1.4-2.2 g·kg-1·day-1) for women at all stages of menstrual function (pre-, peri-, post-menopausal, and contraceptive users) with protein doses evenly distributed, every 3-4 h, across the day. Eumenorrheic athletes in the luteal phase and peri/post-menopausal athletes, regardless of sport, should aim for the upper end of the range. Let's do the math.  130lb woman  Convert to kg: 59 129 g protein    150lb woman  Convert to kg: 68 149 g protein  This is the equivalent of 1 g protein per lb of body weight. You can keep it easy by remembering that is your daily AND that a “dose” of protein needs to be at least 30gm at a meal. However, if you go higher as suggested for your first meal of the day, the next meal may not need to be as high if you eat within 3-4 hours to keep that muscle protein synthesis up. The alternative is muscle protein breakdown. You're in one or the other. There's really not a neutral.  To Lose Weight for Active Women, Examples of a day of high protein meals:  Pre-Workout: 20 gm protein in a simple shake pre-workout  Or minimally, 12 gm protein in two eggs pre-workout Meal Examples:  45g protein in a post- workout smoothie  51g Salmon (35) + quinoa (6) + Greek-style yogurt (10) with berries  43g Taco Salad with ground Bison (35) + Black beans (8)  46g 6 large Sauteed Scallops (29) + Three-bean salad (8) + Black Bean Brownie (9)  I'm not an advocate of calorie counting. However, a snapshot of the number of calories you take in can be helpful. Many women are too far below what they need, AND too low in protein, AND not lifting weights with adequate intensity or sleeping. Those will add up to muscle loss. You may temporarily think you're successful at the weight loss game, but unless you mitigate it, muscle loss will result in you feeling weaker, less energetic and having a slower metabolism  Weight loss with an on-target activity plan means having a slight caloric deficit with an increased amount of protein from a maintenance phase. Other research I've shared suggests increasing protein by 10-15% above maintenance along with a reasonable deficit if weight loss is needed.  So, let's challenge that.  Do you need weight loss? Or do you need to gain lean muscle? Get very clear. You may need both but someone listening needs to hear this: you don't need weight loss; you need fat loss. That will come with an increase in lean muscle and a decrease in inflammation.  Additionally, to Lose Weight While Active Over 40 Creatine supplementation of 3 to 5 g per day is recommended for the mechanistic support of creatine supplementation with regard to muscle protein kinetics, growth factors, satellite cells, myogenic transcription factors, glycogen and calcium regulation, oxidative stress, and inflammation. Postmenopausal females benefit from bone health, mental health, and skeletal muscle size and function when consuming higher (5g) doses of creatine. References:  Murphy CH, Hector AJ, Phillips SM.

*The information in this podcast is intended for Healthcare Practitioners. Nutrition and exercise recommendations are often generic and seldom consider sex differences, let alone the effect of fluctuating sex hormones that occur through ovulatory cycle or reproductive phases. Exercise physiologist and nutrition researcher, Professor Abbie Smith-Ryan, joins the podcast to shed light on the under-recognised effect of sex hormones on women's metabolism, nutrition and exercise performance. Listen in as Abbie discusses the influence oestrogen and progesterone have on female physiology, such as impacts mitochondrial function, muscle fibre type, bone structure and body composition. Zooming out, Abbie highlights a holistic view and discusses how perimenopausal women can often experience undesirable changes in body composition and performance which can be both a cause and effect of psychological distress during this life stage. Abbie also explores the subtle but meaningful impact fluctuating sex hormones have on macronutrient metabolism and exercise performance in the ovulatory and luteal phase in cyclic women – all of which can have real world impact on the food women eat or how they feel and perform at different stages of their cycle. Finally, in a ‘speed round', Abbie briefly outlines the lesser-known benefits of several nutrients in the context of women's health and performance. Links: Smith-Ryan AE, Cabre HE, Moore SR.

Should you bulk, cut, or maingainFirst off all of this depends on your goals. If you're looking to bodybuild I would say maintaining is not the way.You will see slower progress and if you're looking to be serious about the sport you're going to want to be taking your off season seriously and GROWING.That doesn't mean eat everything in sight and throw out a plan though.Take a calculated approach to your off season just like you would prep. It won't be as rigorous but you want to have a method and plan to progress.Don't let yourself get sloppyBut don't get complacent and caught up in being “lean “ year round.If you're looking to maintain aesthetics and you workout for stress relief, fun, and to boost your confidence I would say maingaining is the way.My definition of maingaining would be eating at maintenance calories or doing a lean bulk-Ive done tons of videos on maintenance calories but a way to roughly calculate your maintenance calories is by using BMRBMR = 10 X YOUR BW IN LBSEx: 10 X 200 lbs = 2,000 kcalThen multiply your BMR by your activity factor to get your maintenance calories2,000 X 1.3 acitvty level (SEDENTARY PLUS 3-6 DAYS OF WEIGHT LIFTING) 1.3-1.6Activity factors range fromSedentary plus 3-6 days weight lifting week 1.3-1.6Lightly active plus 3-6 days o weight lifting week 1.5-1.8Active plus 3-6 days if weight lifting 1.7-2.0Very active plus 3-6 days of weight lifting 1.9-2.2Now to bulk you want to 10-20 percent calories additionUpper end for beginnersLower end for advancedYou should expect between 0.25-0.5% weight gain each weekTo cut you want a 20-30% calories reductionLower end for low body fat and advanced level ( these individuals usually have more muscle mass so they need a less decrease in food to start so that muscle sticks around better)Higher end for high body fat and beginnersShould expect 0.5-1.0% weight loss per weekSo again to overview bulking is the way to go in the offseason as a bodybuilder and obviously cutting would be prep but those numbers would vary/be different depending on the athlete (PED usage, genetics, etc.)If you're working out to maintain quality of life, have fun, and just be jacked and shredded id say maingaining would be the way for you year round but its whatever floats your boat!ReferencesJ3 University Nutrition ModulesLenzi, Jaqueline L.1; Teixeira, Emerson L.1; de Jesus, Guilherme1; Schoenfeld, Brad J.2; de Salles Painelli, Vitor1,3 Dietary Strategies of Modern Bodybuilders During Different Phases of the Competitive Cycle, Journal of Strength and Conditioning Research: September 2021 - Volume 35 - Issue 9 - p 2546-2551 doi: 10.1519/JSC.0000000000003169Schoenfeld BJ.

Today we dive into one of my favorite macros: PROTEIN!   Protein is an amazing nutrient that is absolutely essential to building and maintaining muscle strength. In today's episode, I am  breakin' down protein quality, quantity and timing.   Did you know as we age, our bodies start to utilize protein differently? I'm going to fill you ladies in on how we can keep reaching and exceeding our strength goals, even as we age.    Not all protein is created equally, and different types have different functions. I go over the difference between whey concentrate, whey isolate, casein, as well as pea and soy protein and give you the tools to navigate the protein supplement isle to best fit your personal needs.  We even cover collagen protein. Is it the future of skin care or fad?    Give this episode a listen if you want the basics on how to become the most awesome protein princess!  Click here for my favorite gelatin shot for injury prevention.  Click here for shop my online dispensary for some my favorite protein powders!    If you are in need more support in reconstructing a healthy relationship with food I got you covered friend!    Step 1: Enroll in Fuel Her Awesome Food Foundations (e-book and fuel plan included!)  Step 2: Work with me 1:1- email me at jessbrownrd@gmail.com to get my coaching menu! Step 3: Be free to be awesome. You always were, but now it is amplified!  Can't wait to chat with you babes next time, until then… cheers and happy (protein) eating.  Jess Resources: 1. Antonio J, Ellerbroek A, Evans C, Silver T, Peacock CA.

Hoy un programa que voy a dedicar a todas aquellas personas que han luchado, estan luchando y lucharan por el cáncer de mama. Ya que hoy es su día mundial. Esperemos que más pronto que tarde se encuentre solución a esta enfermedad. Un abrazo muy fuerte a todas ellas! Hoy un un programa en el que vamos a desarrollar un tema muy interesante y que está siendo constantemente puesto encima de la mesa ya que tiene muchas opiniones distintas de mucha gente. Cada cuál dice lo suyo. El tema en concreto es la saber qué cantidad de proteína podemos absorber en una sola comida. Lo explicaré detalladamente mediante el siguiente estudio: Schoenfeld BJ, Aragon AA. How much protein can the body use in a single meal for muscle-building? Implications for daily protein distribution. J Int Soc Sports Nutr. 2018;15:10. Published 2018 Feb 27. doi:10.1186/s12970-018-0215-1 Pero antes, como siempre comentaros que en marcpadrosafit.com tenéis cursos para aprender sobre entrenamiento y nutrición. Básicamente todo lo que necesitáis para mejorar vuestra salud de una forma sencilla y muy detallada. Cada semana tenéis un nuevo curso. Si me queréis proponer algún tipo de curso decídmelo en el apartado de mi página web: marcpadrosafit.com/contactus. Y ahora sí sin más dilación, empezamos con la explicación de este interesantísimo estudio en el que sabremos qué cantidad de proteína podemos absorber en una comida. Y es que como bien sabes, mucha gente afirma que más allá de 20-25 g de proteína por comida, todo lo demás no se ingiere sino que se usa para la urea y otros ácidos orgánicos, verdad? Seguro que lo has escuchado más de una vez. Pues bien ahora mismo vamos a salir de dudas. 1. La afirmación que sólo se asimilan unos 20-25 gr. de proteína solo es así en proteínas de absorción rápida como puede ser las que nos bebemos en los batidos sin añadir ningún otro macronutriente. 2. El consumo de proteínas de absorción más lenta como la carne o el pescado, se retrasaría la absorción, y por lo tanto mejoraríamos a utilización de los aminoácidos de estos alimentos. 3. Incluso realizando comidas que lleven 60 - 80 gramos de proteína pueden llegar a ser asimiladas. 4. Así que como conclusión final de este estudio podemos afirmar que realizar menos comidas, por ejemplo 2 -3 con una cantidad mas elevada de proteína que lo que se hace normalmente también puede ser efectivo para un aumento de masa muscular. 5. Una vez hemos visto los resultados de este estudio personalmente te diría que escogieras el número de comidas que mejor te vaya para tu día a día y que dentro de estas comidas esté la cantidad adecuada de proteína para ti. De esta forma nos aseguramos que cumples con los requisitos mínimos de proteína al día. 5. Os recuerdo que el objetivo mínimo de proteínas para un deportista va de: 1,5 g / kg / día y hasta 2,2 g / kg / día según el objetivo y el método utilizado. Dependerá de muchos factores, edad, sexo, actividad física, deporte, pero se movería dentro de estos rangos.

«Du må bli en god fettforbrenner for å gjøre det bra i utholdenhetsidrett», er noe du ofte hører, og da mange fikk nyss i at sykkellaget Team Sky holdt på med noe man kalte fettadaptasjon var det mange som ble inspirert til å hente ut de samme fordelene. Men er det slik at man kan lære kroppen å forbrenne mer fett? Hvordan fungerer egentlig strategiene for fettadaptasjon og hvem passer de for? Vi får svar på dette og mye mer fra vår gjest Andreas Stokkeland. Han er for mange kjent som mannen bak informasjonskontoen @maksprestasjon på Instagram, men det Stokkeland egentlig gjør er å blant annet bruke sine 5 år med ernæringsutdanning til å drive Holmenkollen Treningslab, veilede og trene idrettsutøvere og hvermannsen både online og fysisk. Andreas Stokkeland har detaljert kunnskap om ernæringsstrategier for fysisk prestasjonsevne og lærer oss om dem på pedagogisk vis slik at alle kan forstå.

Consider the classic understanding that high carbohydrate intakes are necessary for optimal endurance performance. What if that failed to take into account the physiological changes that occur with adaptation to low carbohydrate diets? In this podcast, @JohannWindt interviews physician-researcher Dr. Stephen Phinney about his last 30 years of research into low-carb ketogenic diets. Highlights include the previously undocumented levels of during exercise fat oxidation seen in endurance athletes adapted to a low carbohydrate diet. He also touches on ketogenic diets’ potential benefits in other sporting contexts, addresses common criticisms, and looks ahead to future research questions in the field. Further reading and papers discussed in the podcast are included below. Vermont and MIT Study Dr. Phinney’s original two studies on low carbohydrate performance.
