30 minutes theory, some people say it is 1 hour. Later, students studying medicine and biology said that as long as they started exercising, they would burn fat. Of course, the more they burn, the more glycogen they consume at first.

Let's talk about my personal experience. I usually run more, especially in the last year or so. Basically, it's more than 1 hour every time, but I haven't lost weight (of course, I don't run to lose weight), so I come to the conclusion that if I want to lose weight by running, I must control my mouth and eat as much as I run. Like me, I hardly control my diet and often have a drink after running. It is absolutely impossible to lose weight.

For example, a score above 30 and a score above 1 hour are not necessarily scientific, but some words are reasonable, such as "shut up and take your legs", and both are indispensable.
