Protein target for muscle
A widely shared fitness thread recommended prioritizing protein at about 1.2–1.6 grams per kilogram of body weight, with examples like chicken, eggs and tofu and practical swaps such as yogurt with dates to curb sweets.

Protein is the raw material your body uses to repair and build muscle, and sports-nutrition guidance says most people who train need more than the bare minimum. The International Society of Sports Nutrition says 1.4 to 2.0 grams per kilogram of body weight per day is sufficient for most exercising adults. (link.springer.com) That range sits above the Recommended Dietary Allowance, or RDA, for healthy adults, which is 0.8 grams per kilogram per day. The RDA is designed to prevent deficiency in the general population, not to maximize muscle gain from resistance training. (heart.org) (link.springer.com) A 2022 systematic review of 74 randomized controlled trials found that extra protein produced small additional gains in lean body mass in healthy adults doing resistance exercise. The same review found the clearest benefit at 1.2 to 1.59 grams per kilogram per day in adults 65 and older, and at 1.6 grams per kilogram per day or more in younger adults. (pmc.ncbi.nlm.nih.gov) Resistance exercise is the trigger, and protein is the building supply. The sports-nutrition position stand says lifting weights and eating protein work together to raise muscle protein synthesis, the process that repairs and builds muscle tissue. (link.springer.com) The same position stand says a practical target per meal is about 0.25 grams of high-quality protein per kilogram of body weight, or roughly 20 to 40 grams. It also says spreading protein across the day every three to four hours is an evidence-based way to cover total intake. (link.springer.com) Whole foods can hit those numbers without powders. The position stand says physically active people can meet protein needs through food, and common options include dairy, eggs, meat, fish, soy foods, beans, and lentils. (link.springer.com) (hsph.harvard.edu) Fiber is a separate target, but it often shows up in the same meal-planning advice because it affects fullness and bowel habits. The Academy of Nutrition and Dietetics says most adults should aim for about 14 grams of fiber per 1,000 calories, which works out to roughly 25 grams a day for women and 38 grams for men. (eatright.org) Psyllium, sold in South Asia as isabgol, is one of the best-studied fiber supplements. A 2025 review described psyllium husk as a viscous, gel-forming fiber linked to satiety, glycemic control, and gastrointestinal health. (pmc.ncbi.nlm.nih.gov) Fruit can help on the fiber side too. The United States Department of Agriculture’s FoodData Central is the federal database dietitians use to check fiber content in foods such as guava and other produce. (fdc.nal.usda.gov) The caution from clinicians is that more protein is not automatically better. Stanford Medicine nutrition experts wrote on March 25, 2026, that protein is essential but has taken on a “health halo,” and they warned that chasing protein can crowd out fruits, vegetables, and other foods people already under-eat. (med.stanford.edu) The practical takeaway is narrower than social media makes it sound: lift regularly, hit a daily protein range that matches your training, and do not ignore fiber. The evidence is strongest for a routine that combines resistance exercise, adequate total protein, and a diet built from regular foods. (pmc.ncbi.nlm.nih.gov) (link.springer.com)
