The three types of nutrients for energy are all necessary.

Protein is essential and should always be of high quality. Choose complex carbohydrates and fats should be unsaturated and consumed sparingly. 

Increase dietary fiber intake adequately.

Dietary fiber intake makes the body feel full which helps curb overeating. It also helps by enhancing gastrointestinal motility, speeding up the metabolism and preventing constipation.

Sufficient vitamins can prevent obesity.

Vitamin A and D can inhibit the increase of fat cells and is good to maintaining the figure. Sufficient Vitamin C intake produces enough carotene to consume fat so the body doesn't store it. Vitamin B1 and B2 are necessary in the conversion from fat to energy. They can burn fat and help you avoid gaining weight.

Supplement minerals adequately.

Iodine helps with raising metabolism and energy consumption; thus it can help you achieve your goals of weight loss and weight control. Potassium balances sodium in the body, preventing sodium retention, which helps to eliminate edema in the body.
