Why does protein need vary by activity level?
More active individuals need more protein to repair muscle and support recovery. Sedentary people need less.
Is this suitable for weight loss?
Yes, higher protein intake (around 1.6-2.2 g/kg) can help preserve muscle during a calorie deficit.
Can I get enough protein from food alone?
Most people can meet their needs with a balanced diet, but athletes may need to plan meals carefully or use supplements.
