Protein keeps you full, protects muscle as you age, and has the highest thermic effect of any macronutrient. Here’s what different foods actually deliver — and how to hit a solid daily target without supplements.
Protein per typical serving
- Chicken breast (4 oz cooked): ~35 g
- Salmon or tuna (4 oz): ~25–30 g
- Lean beef or pork (4 oz): ~28–32 g
- Greek yogurt, plain (1 cup): ~17–20 g
- Cottage cheese (1 cup): ~25 g
- Eggs (2 large): ~12 g
- Tofu, firm (½ block): ~18–20 g
- Tempeh (4 oz): ~20 g
- Lentils or black beans, cooked (1 cup): ~15–18 g
- Edamame (1 cup): ~17 g
- Nuts and seeds (1 oz): ~5–7 g
How much do you need?
The official minimum (0.8 g per kg of body weight) prevents deficiency; most research on satiety, body composition, and healthy aging points somewhat higher — roughly 1.2–1.6 g/kg for active adults, which for a 170-lb person is about 90–120 g a day. Spread it out: your body uses protein best in 25–40 g doses per meal rather than one giant dinner.
A 100-gram day, no powder required
Greek yogurt + chia at breakfast (~22 g) · chicken salad at lunch (~35 g) · cottage cheese or edamame snack (~15 g) · salmon and rice at dinner (~28 g).
Choosing among protein sources
Different protein foods bring different extras along with them. Fish, especially salmon and sardines, adds omega-3 fats. Beans, lentils, and edamame add fiber and minerals like potassium and magnesium. Greek yogurt and cottage cheese bring calcium. Eggs are inexpensive and quick to cook. Rotating through several sources over the week, rather than leaning on one, gives you a broader mix of nutrients and keeps meals from getting repetitive.
If you find it hard to reach your target, start with breakfast, which is often the lowest-protein meal of the day. Swapping a pastry or plain toast for eggs, Greek yogurt, or cottage cheese can add 15 to 25 grams before mid-morning. From there, make sure lunch and dinner each include a palm-sized portion of protein, and use snacks like edamame, nuts, or a glass of milk to fill any remaining gap.
