Obesity and overwight : Treatments and drugs

Overweight and obesity are defined as abnormal or excessive fat accumulation that presents a risk to health. A crude population measure of obesity is the body mass index (BMI), a person’s weight (in kilograms) divided by the square of his or her height (in metres). A person with a BMI of 30 or more is generally considered obese. A person with a BMI equal to or more than 25 is considered overweight.

2. Diet to treat obesity

Cause malabsorption energy in the intestine

Eat more fiber: a reduction of energy absorption in the intestine is not much.
- Use wrap to reduce the absorption of calories, this measure is less accepted.
- Using an inhibitor of hydrolysis of starch to reduce the absorption of calories: do not cause weight loss.
Eat fat substitutes such as sucrose polyester will cause unrest because they can not absorb the fat-soluble vitamins

The above measures are likely to cause malabsorption syndrome should be less accepted in the market.
Thus, measures to limit absorption should not be used except to eat more fiber such as fruits and vegetables both reduce energy absorption of vitamins and trace elements and easy to digest.Treatment of obesity by a  Low calorie diet

Low calorie meals, easy to implement, effective
- Cons: prone to imbalance food components leads to imbalance of trace elements, so the additional need to learn to adjust.
- Cons:
Complete fasting to lose weight
Dietary with lowest calories (400 - 700 k cal)
- The effect of weight loss of 1.5 - 2.3 kg / week
