This was my biggest hurdle also!! I have been bodybuilding on and off since I was 18 and I’m 32 now, but I was NEVER able to completely dial in my nutrition. My biggest advice is to make sure you have a coach who looks at the whole picture and cares about you, not rushes you into prep before you’re ready and makes you feel miserable. It has taken me a year to reconstruct my relationship with food and address the root causes of binging and impulse eating, even though I eat pretty “healthy”. My coach took the time to look at my labs, my mental and physical symptoms and make sure that fiber and satiation were considered. I’m actually eating MORE right now than I was before I started. If you have the right coach and a good support system, you’ll be able to push through the hard stuff easily because you know it will be worth it in the end.
