First: basic metabolism does not determine your fat loss (fat loss areas) (determine your fat loss metabolism is metabolism!
The basic metabolism consists of: 60% internal organ consumption +20% muscle consumption +15%~20% brain consumption
When you lose fat, you lose fat, you lose water, you lose muscle
And we all know that the bigger an object is, the more energy it takes to keep it going, and the same goes for people.
Second: a low-gi diet can't help you lose fat. A high-gi diet can also help you lose fat
And a new scientific study finds that a long-term low-gi diet doesn't necessarily mean that high-gi foods lose more fat. So low-gi foods are just as effective at reducing fat in the long run as high-gi foods. Low GI has a little-understood drawback: because it is difficult to digest, it passes through the gut carrying nutrients that have not yet been digested or absorbed. So if you eat a single diet and eat a lot of dietary fiber, you are likely to have nutritional problems that are not balanced.
Thirdly, protein is helpful for fat reduction
Fifth: fat-reducing supplements are of no use
