But i think every one need to eat in a balance sequence. like use fruits, vegetables, meat, fish, chicken in a proper manner. A normal person use daily 2200 to 2400 calories per day. But if he did not burn calories more then that then the result in over weight. So calories have important impact on body weight.
actually there are several nutritional needs other than calories, and each person is different.
and weight is not a clear sign of poor health, muscle weighs more than fat, height and build can change the ideal weight, amount of physical exertion, climate and many other things can alter the amount of calorie intake needed per day.
there is also the individual persons ability to absorb nutrients, and store them, which can alter the amount of nutrients needed.
