Complementing habitual diet with a mixed plant-based protein blend (soy/pea) yields equivalent resistance training-induced muscle mass and strength gains compared to animal-based protein (whey) in healthy young men.

If you are doing resistance training, you do not need to buy whey protein to build muscle. You can use a blend of plant proteins (like soy and pea) instead. Take 15 grams of this blend three times a day with your main meals. This will help you gain muscle and strength just as well as animal protein, provided you are eating enough total protein and training consistently.

An additional daily protein intake of 1 g/kg from supplements, resulting in a total daily intake of approximately 2 g/kg, is most effective for enhancing athletic performance.

Aim for a total daily protein intake of about 2 g/kg of body weight. If you eat enough protein from food, you may not need supplements. If you use supplements, adding 1 g/kg/day of protein powder is likely the optimal amount for performance gains.

Diets high in fiber, low-glycemic index carbohydrates, and healthy fats contribute to better glycemic control and reduced HbA1c levels in Type 2 diabetes.

Prioritize high-fiber, low-glycemic foods like whole grains, vegetables, legumes, and lean proteins. Include healthy fats and limit processed sugars. This approach helps prevent sharp blood sugar spikes and improves long-term control.

Under energy-matched conditions, low-carbohydrate diets (≤44% TDCI) produce greater reductions in fasting blood glucose, fasting insulin, triglycerides, and HDL cholesterol compared to high-carbohydrate diets (≥45% TDCI).

If you want to improve your fasting blood glucose and insulin levels without changing your total calorie intake, try reducing your carbohydrate intake to below 44% of your total daily calories. This shift, while keeping total energy the same, has been shown to significantly improve these metabolic markers compared to eating more carbohydrates.

Under energy-matched conditions, low-carbohydrate diets (≤44% TDCI) lead to greater reductions in body mass and fat mass compared to high-carbohydrate diets (≥45% TDCI).

If your goal is to lose fat, reducing your carbohydrate intake to below 44% of your total daily calories may be more effective than eating more carbohydrates, even if you keep your total calorie intake the same.

Trans-fatty acids produced through partial hydrogenation increase the risk of ischemic heart disease, whereas saturated and monounsaturated oils are more stable and safer for high-temperature cooking.

When cooking at high heat (frying, searing), use stable fats like butter, ghee, or high-oleic oils. Avoid heating polyunsaturated vegetable oils (like soybean or corn oil) to high temperatures, as they break down into harmful compounds. Trans-fats from partial hydrogenation are harmful and should be avoided.

Adherence to the DASH diet or the Plate Method leads to improved glycemic control, reduced HbA1c, and better blood pressure management in patients with Type 2 Diabetes.

Adopt the DASH diet or the Plate Method. For DASH, focus on fruits, vegetables, whole grains, and low-fat dairy while limiting sodium and saturated fats. For the Plate Method, fill half your plate with non-starchy vegetables, one-quarter with lean protein, and one-quarter with carbohydrates. These approaches have been shown to lower HbA1c and improve blood pressure.

Combining GLP-1RA therapy with resistance exercise and high protein intake preserves fat-free mass better than GLP-1RA therapy alone in older adults with obesity.

To get the most benefit from GLP-1 medications without losing muscle, you must also do resistance exercise (like weights) at least twice a week and eat enough protein (1.0-1.2g per kg of body weight). This combination helps you lose fat while keeping your strength.

Post-exercise carbohydrate intake of approximately 1.2 g/kg body mass per hour for up to 4 hours is essential for restoring glycogen reserves, supporting immune system energy needs, and facilitating tissue repair.

After your workout, eat about 1.2 grams of carbohydrates for every kilogram of your body weight each hour for the next 4 hours. For example, if you weigh 70kg, aim for 84g of carbs per hour. This helps refill your energy stores and supports your immune system. Don't fear carbs here; they are essential for recovery.

Post-exercise ingestion of high-quality protein (0.3–0.5 g/kg body mass) stimulates net muscle protein anabolism and contributes to faster tissue growth and repair.

After your workout, consume 0.3 to 0.5 grams of high-quality protein for every kilogram of your body weight. For a 70kg person, this is 21-35g of protein. This helps build and repair muscle tissue.

Pre-sleep nutrition, specifically casein- or protein-rich meals with slow digestion rates, has a restorative effect on the musculoskeletal, endocrine, immune, and nervous systems.

Eat a slow-digesting protein source, like casein or Greek yogurt, before bed. This helps your body recover and repair tissues while you sleep. Don't worry about fat gain if your total daily calories are on track.

Patients treated with GLP-1 based therapies must increase protein intake to 1–1.5 g/kg bodyweight/day and engage in resistance training to mitigate the loss of lean body mass (LBM) and prevent sarcopenic obesity.

If you are taking a GLP-1 medication like Ozempic or Wegovy, you must eat more protein than the standard recommendation. Aim for 1 to 1.5 grams of protein per kilogram of your body weight every day. Additionally, you must lift weights or do resistance exercises at least twice a week. This combination is the only proven way to stop your body from eating its own muscle while you lose fat.

Resistance training preserves or increases lean muscle mass and improves muscle quality in adults with obesity, even when combined with energy-restricted diets or obesity management medications that typically cause lean mass loss.

Incorporate resistance training into your routine to protect your muscle mass. This is especially important if you are dieting or taking weight-loss medications, as these can cause muscle loss. Focus on strength and function rather than just size.

A daily protein intake of approximately 1.6 grams per kilogram of body weight is recommended to spare lean body mass during weight loss induced by GLP-1 medications.

When losing weight on GLP-1s, aim to eat approximately 1.6 grams of protein for every kilogram of your body weight each day. This specific target helps protect your muscle mass from being lost along with the fat.

Protein supplementation combined with resistance training is the most prominent and effective intervention strategy for promoting muscle hypertrophy.

To maximize muscle growth, combine regular resistance training with adequate protein intake. This combination is the most widely supported strategy in current research. Ensure your training is progressive, as protein alone is not enough to overcome adaptation plateaus.

Whey protein supplementation significantly enhances muscle strength and fat-free mass gains compared to placebo, but is less effective than collagen.

Whey protein works for building muscle and strength, but the gains are smaller than those from collagen. If you are using whey, consider adding collagen to your regimen for potentially better results. Don't rely on whey alone if you want to maximize your strength and mass gains.

Replacing processed animal meats with plant-based meat analogues (PBMAs) significantly reduces saturated fat and total energy intake while increasing dietary fiber, leading to more favorable Nutri-Score ratings in most categories.

Switching from processed animal meats (like sausages and bacon) to plant-based analogues generally lowers your saturated fat and calorie intake while boosting fiber. However, check the label: many analogues are high in salt and sugar, and few are fortified with B12 or Iron. Choose products with lower sodium and consider a B12 supplement if you rely heavily on these substitutes.

Dietary protein intake supports but does not independently drive skeletal muscle hypertrophy; its primary role is to amplify the anabolic response to resistance exercise.

Eat enough protein (1.2-1.6 g/kg/day) to support your training, but do not expect it to build muscle on its own. The key to muscle growth is resistance exercise. Protein helps maximize the gains you get from your workouts.

Female endurance athletes unintentionally underfuel with carbohydrates relative to training volume, creating a cumulative energy deficit, while simultaneously prioritizing protein intake to meet or exceed recommendations.

Female endurance athletes should prioritize carbohydrate intake on training days to match volume, as deficits increase significantly with higher loads. Do not neglect rest days; even low-intensity sessions require adequate fuel to prevent cumulative energy deficits. While protein intake is often correctly prioritized, ensure it does not displace necessary carbohydrates. Address psychological barriers like body image and time constraints by planning simple, accessible carbohydrate sources for all training days, not just hard sessions.

A very low carbohydrate-low protein (VLCLP) diet is the most effective macronutrient ratio for weight loss compared to a moderate fat-low protein (MFLP) control diet, achieving a mean weight loss of 4.10 kg.

If your primary goal is weight loss, a diet very low in carbohydrates (≤30% of calories) and low in protein (≤30% of calories) appears more effective than high-protein low-carb diets. This approach outperforms standard moderate-fat diets. Ensure you are overweight or obese, as results in normal-weight individuals are not well-established.

GLP-1 receptor agonists (semaglutide) and dual GLP-1/GIP agonists (tirzepatide) cause significant lean mass loss during weight loss, with semaglutide losing approximately 45% of total weight as lean mass and tirzepatide losing 25.7%, posing a specific risk of frailty and fractures in older populations.

If you are taking semaglutide or tirzepatide, be aware that a significant portion of your weight loss (up to 45% for semaglutide) comes from lean mass, not just fat. This is especially risky if you are over 60. Discuss strategies to preserve muscle, such as resistance training or potentially newer combination therapies, with your provider.

High intake of saturated fatty acids (SFA) from modern domesticated animal products and dairy increases LDL cholesterol and cardiovascular disease risk compared to ancestral diets rich in unsaturated fatty acids.

Prioritize unsaturated fatty acids (especially omega-3s) and fiber-rich foods over high-fat dairy and fatty cuts of domesticated meat. This shift aligns your diet with evolutionary norms and helps lower LDL cholesterol, reducing cardiovascular risk.

High intake of saturated fatty acids from modern diets is linked to endotoxemia and inflammation, whereas unsaturated fatty acids do not produce this response.

Be aware that high-fat meals, particularly those high in saturated fat, can trigger an inflammatory response (endotoxemia). Choosing unsaturated fats helps avoid this inflammatory spike.

A higher proportion of saturated fatty acids relative to total fat intake (SFA/TFAT) is associated with a 23% increased risk of all-cause mortality, whereas a higher proportion of polyunsaturated fatty acids relative to total fat (PUFA/TFAT) is associated with a 14% reduced risk, mediated partially by the neutrophil percentage-to-albumin ratio (NPAR).

To support longevity, focus on the ratio of fats in your diet rather than just cutting total fat. Ensure that polyunsaturated fats (found in fish, nuts, seeds, vegetable oils) make up a larger proportion of your total fat intake, while saturated fats (found in red meat, butter, cheese) make up a smaller proportion. This shift is associated with lower mortality risk, potentially by reducing systemic inflammation.
