Gender, height, age, and genetics all play a role in determining our ideal weight. Obesity and overweight people are at a higher risk for a variety of ailments, including diabetes, heart disease, and cancer.

Excess body fat is the result of eating more than we require. Extra calories can be obtained from any caloric food, including protein, fat, carbohydrate, and alcohol, although fat is the most concentrated source of energy. Physical activity allows us to expend energy while also making us feel good. The message is straightforward: if we are gaining weight, we must eat less and exercise more!
