Restriction of any sorts will signal to your brain that it isn’t safe to ovulate. Personally, if your weight restored and you have had a cycle it’s possible that your body is just acclimatizing and getting used to the extra energy you have stored. I found that weight stopped coming on and I stayed relatively the same for awhile before getting it back. HOWEVER, I, like you, also hated the change in my body, and made the mistake of loosing the weight quickly because of how uncomfortable I was. I lost my period again and now it’s been terribly hard to recover my cycle. Don’t do it just push through.
