How Much Protein Do You Really Need
By Yvette Malcolm • February 9, 2026

Protein requirements vary based on your activity level, age, and health goals. The baseline recommendation is 0.8 grams per kilogram of body weight daily for sedentary adults. However, if you're physically active, building muscle, or recovering from illness, you'll need more—typically 1.2 to 2.0 grams per kilogram. For a 150-pound person, that's roughly 55-136 grams daily depending on lifestyle.
The key is spreading protein throughout your day. Your body can only process about 25-30 grams per meal effectively for muscle synthesis. Quality matters too—complete proteins from meat, fish, eggs, and dairy provide all essential amino acids, while plant sources like beans and quinoa may require combining for optimal nutrition.

Sedentary Adults
0.8g per kg body weight. Minimal physical activity means baseline needs.

Active Individuals
1.2-1.6g per kg. Regular exercise increases protein demands for recovery.

Athletes & Bodybuilders
1.6-2.0g per kg. Intense training requires maximum protein for muscle growth.
