Hey man,
After doing (actual) wrestling in high school, I learned some useful weighloss relevant stuff:
First thing, water weight is not the weight you're looking to lose, you need to be hydrated to function properly, and the gain associated with hydrating is gonna be taken out naturally.
Secondly, going gluten free (as i've done for a while now) is mad helpful.
Gluten is found in most grains, like wheat and junk, and so breads and pastries and stuff all have it.
What it does is hold food together and make them "springier," but it also makes food sit in your stomach and you feel bloated and junk.
When you go gluten free food digests much quicker, and on the side you lose some weight.
I'm not saying to never eat bread, but to only cut back.
Best of luck man, I have no doubt you can do it.
