Although it might sound a bit broscientific, it's the best way I can describe a phenomenon experienced by me and millions of other athletes around the world. The body seems to have a weight (a <a href="https://fitose.com/delta-prime/">Delta Prime </a> nd, accordingly, a body fat percentage) that it is most comfortable at. Your natural appetite tends to maintain this weight and if you eat less than this, you feel hungry. If you eat more than this, you feel quite full.
