Comparison of physical fitness changes within 20 days
If you consume more calories than you absorb, being thin is inevitable. Maybe as you said, the fat hasn't lost much, and the muscles are already growing, so you may be fatter at this time. It'll be all right in a minute. The same weight, only a little muscle, but a lot of fat, so if you continue to exercise like this, even if your weight remains the same, you will look thinner, smaller and better.
