Is diet useful for weight loss?

Does diet help you lose weight and does diet have an effect on the skin?

Dr. Hani Kamal, consultant on obesity and nutrition, answers this question by saying:
For diet, ice cream, carbonated water and diet are a big lie, the calories found in them are not less than normal except 30 or 40 calories in addition to containing cream and other ingredients that are not useful for those who want to lose weight.

But it does not prevent that these ingredients can be used to stabilize weight but for diet and skin some experts have linked food and the problem of acne but doubt still exists about the extent to which diet affects the skin, with age the body is less able to absorb vitamins from food that benefits the Therefore it is necessary to pay attention to eating foods that benefit the skin or eating the vitamins and minerals needed by the skin through nutritional additives and thus not only benefit the skin but improve health in general.
