Protein Intake Guide: How Much Protein Do You Really Need?
Protein supports muscle repair, satiety, and metabolic health—but needs vary widely by goal, age, and training status.
Daily Protein Targets by Goal
| Goal | Protein (g/kg body weight) | Example (70 kg person) |
|---|---|---|
| Sedentary adult (RDA baseline) | 0.8 g/kg | 56 g/day |
| Active / recreational training | 1.2–1.6 g/kg | 84–112 g/day |
| Muscle gain / strength focus | 1.6–2.2 g/kg | 112–154 g/day |
| Fat loss (preserve lean mass) | 1.6–2.4 g/kg | 112–168 g/day |
Use our macronutrient calculator and TDEE calculator to set calories first, then allocate protein within your macro split.
Why Protein Matters
- Muscle protein synthesis: Amino acids rebuild tissue after training
- Satiety: Higher protein meals reduce hunger during calorie deficits
- Thermic effect: Protein uses more energy to digest than carbs or fat
- Recovery: Supports immune function and connective tissue repair
Best Protein Sources
Prioritize whole foods: chicken, fish, eggs, Greek yogurt, legumes, tofu, lean beef, and dairy. Whey or plant protein powders can fill gaps when whole-food meals are impractical—they are supplements, not replacements for a balanced diet.
Spread intake across 3–4 meals with 25–40 g protein per meal for most people. Read our macronutrients guide for balancing carbs and fats alongside protein.
Protein Myths
- Myth: More protein always means more muscle. Fact: Training stimulus and total calories matter; excess protein is oxidized or stored, not infinitely converted to muscle.
- Myth: You must eat protein within 30 minutes post-workout. Fact: Total daily intake over 24 hours is more important for most people.
- Myth: High protein damages healthy kidneys. Fact: In people with normal kidney function, high protein diets are generally safe; those with kidney disease should follow medical guidance.
