Anyhow, I will do so.
Leptin is a hormone in the body that you could say works inversely with another hormone called grehlin.
When you body is functioning properly they are at a balance, when you are sleep deprived and food deprived levels of grehlin increase and levels of leptin dip lower, this will cause an increase in appetite and fat storage.
So the idea is, that when on a low calorie diet for an extended period of time then leptin levels decline and grehlin increase, so having a cheat/refeed meal will help to bring those hormones more into balance.
As for the original questions...if you lost all your definition after 2 days than you didnt have much to begin with.
But of course just get back on the same diet that got you your definition in the first place...
