Research-backed daily protein targets for your body weight, activity level, and goal, with a personalized meal plan and food-source servings.
The RDA for protein (0.36g per pound) is the minimum to prevent deficiency, not the optimal amount for health, body composition, or longevity. Research consistently shows that active adults benefit from 0.7-1g per pound for muscle preservation, improved satiety, and better body composition during weight loss. Spreading protein across 3-4 meals of 30-40g each maximizes muscle protein synthesis better than eating the same total in 1-2 large meals.
The RDA (Recommended Dietary Allowance) for protein is 0.8 g per kg of body weight, but this figure represents the minimum to prevent deficiency in sedentary adults, not the optimal amount for health, body composition, or performance. For anyone who exercises regularly, current research consistently points to significantly higher targets.
The International Society of Sports Nutrition (ISSN) recommends 1.4–2.0 g/kg for exercising individuals, while research on muscle hypertrophy specifically points to 1.6–2.2 g/kg as the range where muscle protein synthesis is maximized. During a caloric deficit (fat loss phase), requirements increase further, 2.3–3.1 g/kg of lean body mass, because protein helps preserve muscle tissue when calories are restricted.
| Goal | Min (g/kg) | Optimal (g/kg) | Max useful (g/kg) | Notes |
|---|---|---|---|---|
| Sedentary (RDA) | 0.8 | 1.0 | 1.2 | Minimum for deficiency prevention |
| General fitness | 1.2 | 1.4 | 1.6 | Light exercise 1–3×/week |
| Endurance sports | 1.2 | 1.6 | 1.8 | Running, cycling, swimming |
| Maintenance (active) | 1.4 | 1.6 | 2.0 | Preserve mass, moderate training |
| Muscle gain | 1.6 | 2.0 | 2.4 | ISSN hypertrophy recommendation |
| Fat loss (preserve LBM) | 1.8 | 2.4 | 3.1 | Higher needs during deficit; per LBM |
| Body recomposition | 2.0 | 2.4 | 3.1 | Simultaneous cut & build |
| Strength/power athlete | 1.6 | 2.0 | 2.4 | Powerlifting, Olympic lifting |
| Combat sports | 1.6 | 2.0 | 2.4 | Higher during weight-cut phases |
Protein’s primary job is building and repairing lean tissue, muscle, organs, connective tissue. Fat mass doesn’t have meaningful protein turnover, so it doesn’t increase protein requirements. Using lean body mass (LBM = total weight − fat mass) as the basis for protein calculations is more accurate, especially for people with higher body fat percentages.
For example: two people both weigh 90 kg. Person A has 15% body fat (LBM = 76.5 kg). Person B has 35% body fat (LBM = 58.5 kg). At the same activity level and goal, Person A needs more total protein than Person B because they have more metabolically active tissue to feed. Total-weight calculations overestimate needs for Person B.
Research shows that spreading protein intake across 3–5 meals produces better muscle protein synthesis than eating the same amount in 1–2 large sittings. The “muscle full” effect suggests that muscle protein synthesis is maximally stimulated by roughly 0.4 g/kg per meal (about 25–40g for most people), after which additional protein in that sitting provides diminishing returns for muscle building, though it still contributes to satiety and other functions.
Post-workout protein matters, but the “anabolic window” is wider than once thought, 3–5 hours rather than 30 minutes. A high-protein meal within a few hours of training is sufficient. Pre-sleep protein (casein or a mixed protein source) also supports overnight muscle protein synthesis, making it a useful strategy for muscle gain.
A complete protein contains all 9 essential amino acids (EAAs) in adequate amounts. Animal sources (meat, fish, dairy, eggs) are complete. Plant sources are typically incomplete or lower in one or more EAAs, but this is easily addressed by combining sources (rice + beans, for example) or eating enough variety throughout the day. Leucine specifically is the key amino acid that triggers muscle protein synthesis, and plant sources generally provide less leucine per gram of protein, meaning plant-based individuals may benefit from slightly higher total protein intake.
