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.

Post-exercise supplementation with 40g of whey protein significantly enhances lower-body strength adaptations (leg 1-RM) in untrained adults performing low-volume intra-session concurrent training, compared to an isocaloric placebo.

If you are new to exercise and doing a mix of cardio and weights, drinking 40g of whey protein right after your workout can help you build more leg strength than if you drank a calorie-matched sugar drink. This is particularly useful if you struggle to eat a full meal immediately after training.

Consuming beef with a favorable fatty acid profile (higher monounsaturated fatty acids, lower saturated fatty acids) significantly improves serum lipid parameters (total cholesterol, LDL, non-HDL, and atherogenic indexes) compared to consuming standard commercial beef, even when the high-MUFA beef has higher total fat content.

If you eat beef, choosing cuts with a better fatty acid profile (higher in monounsaturated fats like oleic acid and lower in saturated fats) can lead to better cholesterol levels compared to standard commercial beef. You don't need to eliminate beef; you can optimize your choice. In this study, eating 120g of this specific beef 3 times a week for just 2 weeks improved LDL and other lipid markers significantly compared to standard beef.

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.

Adherence to a Mediterranean diet, characterized by high intake of olive oil, vegetables, fruits, nuts, legumes, whole grains, fish, and seafood, with low intake of red and processed meat and reduced carbohydrates, offers cardiovascular benefits and is recommended for NAFLD management.

Eat a Mediterranean-style diet: lots of vegetables, fruits, nuts, legumes, whole grains, fish, and olive oil. Limit red and processed meat and keep carbohydrates to about 40% of your calories.

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.

Replacing saturated fatty acids (SFAs) with polyunsaturated fatty acids (PUFAs) reduces the risk of coronary events and mortality, whereas replacing SFAs with carbohydrates increases risk.

Don't just cut fat; swap the right kind. Replace saturated fats (found in palm, coconut, dairy) with polyunsaturated fats (found in fish, flax, sunflower oils). Avoid replacing them with refined carbs, as that increases heart disease risk.

Adherence to the DASH diet lowers systolic blood pressure by 5.5 mmHg and diastolic blood pressure by 3 mmHg.

If you have high blood pressure, follow the DASH diet by eating more fruits, vegetables, and low-fat dairy. This can lower your systolic blood pressure by about 5.5 mmHg and diastolic by 3 mmHg.

Adopting a plant-based vegan diet for 16 weeks significantly reduces body weight, fat mass, and insulin resistance (HOMA-IR) in overweight individuals compared to maintaining a standard omnivorous diet.

Switch to a whole-food, plant-based diet (vegetables, grains, legumes, fruits) with minimal added oils for 16 weeks. You do not need to count calories strictly, but focus on replacing animal proteins with plant sources. This approach has been shown to significantly reduce body weight and improve insulin resistance in overweight adults.

A ketogenic diet (defined as <50g carbohydrates/day) significantly improves body weight, waist circumference, HbA1c, triglycerides, and HDL levels in overweight patients with Type 2 Diabetes Mellitus compared to other dietary interventions.

For overweight individuals with Type 2 Diabetes, adopting a ketogenic diet (under 50g carbs daily) is a highly effective strategy for losing weight and improving blood sugar control. This approach also tends to improve heart health markers like HDL and triglycerides, addressing common concerns about high-fat diets. Consult a doctor to manage medications, as blood sugar levels may drop significantly.

Adhering to a low-fat, plant-based, high-carbohydrate diet for 16 weeks significantly reduces body weight, fat mass, and insulin resistance (HOMA-IR) in overweight individuals compared to maintaining a habitual diet.

To lose weight and improve insulin sensitivity, try a low-fat vegan diet for 16 weeks. Focus on vegetables, grains, legumes, and fruits. Keep fat intake low (20-30g per day) by avoiding added oils and animal products. You do not need to count calories or restrict carbohydrates; in fact, higher carbohydrate intake in this context is linked to greater weight loss. Attend weekly cooking classes if available to learn how to prepare these meals.

Increased intake of total and insoluble fiber, as part of a plant-based diet, is negatively correlated with reductions in BMI, fat mass, and visceral fat volume.

Increase your intake of total and insoluble fiber by eating more whole grains, legumes, vegetables, and fruits. This is associated with greater reductions in body fat and visceral fat. Ensure you drink enough water to help your digestive system adjust to the higher fiber intake.

A ketogenic diet (KD) significantly reduces body weight, BMI, fat mass, waist circumference, visceral adipose tissue, and percentage body fat compared to low-fat diets in adults, but also causes a small reduction in fat-free and lean body mass.

Adopting a ketogenic diet (high fat, very low carb) for 2-96 weeks leads to significant weight loss, reduced body fat, and improved waist circumference compared to low-fat diets. However, be aware that you may also lose a small amount of lean muscle mass (-0.63 kg). This diet is effective for body recomposition in adults, but long-term adherence can be challenging.

A 6-month low-calorie, high-protein diet (35% of total calories from protein) improves glucose metabolism, body composition, and cardiometabolic profiles in subjects with prediabetes or type 2 diabetes and overweight/obesity, regardless of whether the protein source is primarily animal or plant-based.

If you have prediabetes or type 2 diabetes and are overweight, switching to a diet where 35% of your calories come from protein (whether from meat, fish, eggs, beans, nuts, or soy) and restricting your total calories by 30% can significantly improve your blood sugar, weight, and heart health markers. It does not matter if you choose animal or plant proteins; the key is the high-protein, low-calorie pattern itself. Stick to this for at least 6 months for best results.

High-protein isocaloric diets (HPD) preserve or increase muscle mass during weight loss, whereas very low-energy diets (VLED) significantly decrease muscle mass.

If you are losing weight, ensure your protein intake is high (around 1.8g per kg of body weight). This helps you keep your muscle while losing fat. Very low-calorie diets without high protein will cause you to lose muscle mass.

Ketogenic diets (KD) significantly reduce waist circumference compared to other dietary interventions, indicating superior reduction in central adiposity.

If you want to specifically target belly fat (waist circumference), a ketogenic diet (very low carb, high fat) is effective. It significantly reduces waist size compared to other diets, even when calories are not restricted.

Isocaloric diets with macronutrient distribution (LCD, KD, HPD) result in greater weight loss than caloric restriction diets (LED, VLED) in obese women over 12 weeks.

You can lose weight without counting calories if you focus on macronutrients. Diets that adjust carbs, protein, or fat ratios (like Keto, Low-Carb, or High-Protein) can lead to greater weight loss than simple calorie restriction over 12 weeks.

Very Low-Calorie Ketogenic Diet (VLCKD) produces superior weight loss compared to low-carbohydrate diets and is recommended for severe obesity and specific metabolic conditions.

VLCKD is a very strict, low-calorie (<800 kcal) ketogenic diet that produces superior weight loss compared to standard low-carb diets. It is recommended for severe obesity and specific metabolic conditions under medical supervision. It is not suitable for everyone and has strict contraindications.
