The weight loss base is the weight when you start to lose weight. A large base generally means that people with a large base are heavier at first, but some human flesh is stronger and harder to lose weight.

On the other hand, physical foundation refers to the poor balance of body index, that is to say, some people have thin fat accumulation, and it is easier to lose weight if they don't gain weight repeatedly. Especially it is easier to lose weight for the first time. With a large body base, it is difficult to lose fat. Plus, if you get fatter, it will be more difficult to lose weight. You have to work harder than before, because your body has adapted to the previous way of losing weight, so losing weight will not change much.

I think you belong to a small base. If you are tall, you have less fat.
