Gender has an impact on the requirements of a balanced diet. Women have comparatively less
metabolic rate than men of the same age and weight. So men need a balanced diet that provides
comparatively more energy.
Different people have different lifestyles and varied nature of work. A man with sedentary habits
does not require as much energy as the man who is on his feet for most of the day.
