That's pretty unusual, never heard of that. Would you say you were on it >90%? For me within 3 wks I was on perfect body weight and never changed.

When I say I'm doing something that means I am commited to it. Never a cheat day, never waiver. 100% or 0% is the only way I operate.
But yes, I got leaner but never lean. Even now, nearly 20 weeks into a cut, my body is only slowly losing fat while in a deep deficit. Genetics obviously plays a large part in this.
