If you're lifting weights and want to build muscle, eating at least 1.6 grams of protein per kilogram of body weight every day is the biggest factor that helps — more protein means better results, and when you eat it doesn't matter as much.

If you're lifting weights and want to build muscle, eating at least 1.6 grams of protein per kilogram of your body weight every day is the most important thing — and eating even more protein (like 0.5 extra grams per kg) helps you gain a little more muscle on top of that.

If you're a young man who lifts weights regularly, eating 1.8 grams of protein per kilogram of your body weight every day is enough to build as much muscle as you can from training—adding extra leucine powder won't help you get any bigger or stronger.

Eating a big protein meal (100g) after working out makes your muscles keep building for longer than a smaller meal (25g), at least for 12 hours.

If you eat enough protein (like 25g per meal), your muscles will grow even if you eat almost no carbs—carbs aren’t needed for building muscle.

Protein intake at 0.7 grams per pound of body weight is sufficient to maximize muscle protein synthesis in non-elite, non-lean individuals undergoing resistance training.
