Question 1

How much protein do I need per day?

Accepted Answer

General recommendation is 0.8g per kg body weight for sedentary adults. Active individuals need 1.2-2.0g per kg. Bodybuilders and athletes may need up to 2.2g per kg or more.

Question 2

Does activity level affect protein needs?

Accepted Answer

Yes, significantly. Exercise increases muscle protein synthesis and breakdown. More active people need more protein for recovery and growth. Endurance athletes need 1.2-1.4g/kg, strength athletes 1.6-2.2g/kg.

Question 3

Should I eat more protein when losing weight?

Accepted Answer

Yes. Higher protein intake (1.6-2.4g/kg) during a calorie deficit helps preserve muscle mass, increases satiety, and boosts metabolism through the thermic effect of food.

Question 4

Can I eat too much protein?

Accepted Answer

For healthy adults, high protein intake (up to 2.5g/kg) is generally safe. People with kidney disease should limit protein. Excess protein beyond what the body can use for muscle synthesis is used for energy or stored.
