Obesity is caused by unreasonable diet and inactivity.

First of all, don't overeat, don't eat sweets, eat three meals a day reasonably, measure on time, eat less meat and be vegetarian, and have seven full meals.

Get up in the morning and exercise for one hour, stand for 30 minutes after three meals, and exercise at night 1 hour.

And from the experience, I learned how to understand health.
