Protein shakes, bars, and supplements are everywhere. Marketing suggests everyone needs more protein. But how much do you actually need, and are most people really deficient?
The Basic Requirement
The recommended dietary allowance (RDA) is 0.8 grams per kilogram of body weight dailyāabout 56 grams for an average sedentary man, 46 grams for an average sedentary woman. Most Americans easily exceed this through normal diet.
When You Need More
Athletes building muscle benefit from higher intakeāup to 1.6-2.2 grams per kilogram. Older adults need more to prevent muscle loss. Pregnant and breastfeeding women have increased requirements. Vegetarians need to be more deliberate about complete protein sources.
Complete vs. Incomplete Proteins
Animal proteins contain all essential amino acids. Most plant proteins lack one or more. Vegetarians can combine sourcesābeans and rice together provide complete proteināor eat varied plant proteins throughout the day.
Timing Matters Less Than Total
The idea that you must consume protein within 30 minutes of exercise has been largely debunked. Daily total matters more than timing. Spreading intake throughout the day may have modest benefits for muscle synthesis.
Can You Eat Too Much?
Very high protein diets strain kidneys in people with existing kidney issues. For healthy individuals, excess protein simply gets converted to energy or stored as fat. Extremely high intake is unnecessary for most goals.
