Obesity is cause by the accumulation of fat in various organs throughout the body. But the most common is the area under the skin. In males, fat tends to accumulate around the abdomen. It is shape like an apple ( Apple Shape) . Females find that fat tends to accumulate on the hips. The shape therefore went out in a pear shape ( Pear Shape).

At present, medically accepted criteria. It uses body mass index, known as BMI (Body Mass Index). Which is calculate by taking weight. (in kilograms) divided by height squared (in meters). Report from ยูฟ่าเบท

If we weigh 55 kilograms, height 160 centimeters (1.60 meters)  

BMI = 55/ (1.60 x 1.60) = 21.48

The World Health Organization ( WHO) has defined people with a body mass index ( BMI) below 18.5 as underweight and greater than or equal to 25 as overweight ( Overweight) and has divided the severity of weight. The overweight ( Overweight) is 4 levels:

Overweight          with a body mass index of 25.0 – 29.9

Obesity          level 1 has a body mass index of 30.0 – 34.9.

Obesity          level 2 has a body mass index of 35.0 – 39.9.       

         Grade 3 obesity with a body mass index greater than 40.0      

Percentage of fat means the proportion of fat in the body as a percentage. For example, a person weighing 100 kilograms is detecte with a fat mass of 30 kilograms. Indicating that the percentage of fat is 30%. Currently , bio-electrical impedance can measure using this method . It uses electrical signals to measure muscle mass and fat mass. 

The ideal body fat percentage for women should not exceed 25% and for men should not exceed 20%. Many people lose weight by looking only at their weight loss. which is a wrong reduction Because the weight lost usually comes from the muscles. or more body water than fat Therefore, the correct weight loss therefore should look at the percentage of body fat
