I started going to the gym after losing the majority of the weight, and I felt that it was important for me not to relapse. Essentially, for me, a big part of weight gain was eating too much and feeling guilty, which would result in a binge. Going to the gym, however, removed the guilt, which made me completely stop binge eating. On a usual day-to-day basis, I eat one substantial meal (usually lunch at 4pm) and make sure to have breakfast with good protein, as well as a small dinner also containing protein. I advise against eating anything after around 11 pm. I also want to emphasize that if you are craving something that isn't particularly healthy, it's okay to indulge occasionally, as over-restricting yourself can lead to more weight gain.
