◆ Understand obesity
Now the most commonly used way of judging is to define different degrees of obesity according to BMI.
BMI = weight (kg)/height square (m2)
| BMI range | definition |
|---|---|
| 25 ≦ BMI ≦ 29.9 | 【too heavy】 |
| 30 ≦ BMI ≦ 39.9 | 【obesity】 |
| 39.9 ＜ BMI | 【Severe Obesity】 |
At present, more than two-thirds of people try to lose weight or maintain weight. However, only those with 20% can simultaneously reduce their dietary intake and exercise at least 150 minutes a week. The most common difficulty in losing weight and maintaining obesity is that our energy expenditure will decrease with weight loss. Studies have pointed out that when we maintain a weight below the baseline body weight of 10%, energy expenditure will decrease by approximately 8 kcal/kg. Therefore, obesity has become one of the civilization diseases that are difficult to overcome in this century.
