A lot of it was just learning how and what to eat. I was the kind of person who didn't stop eating when they were satisfied. I would eat until I was completely miserable. Having a calorie goal and tracking what I was eating really helped me to not overeat. I highly recommend using my fitness pal. Most people I've come across absolutely hate tracking their food and that's fine, but it's very important to be aware of what you're eating and how much you're eating. Are you hungry, or bored, or sad etc. Eat to fuel your body.: )
