Maybe try eating more small meals throughout the day, and including some protein and maybe something a little sweet like fruit or trail mix that has a little chocolate. This might not be the case for you, but for me if I let my blood sugar go up and down or get too hungry I start craving sweets. I also find staying hydrated helps. Practicing mindfulness around eating might help, too. You could make sure you are paying attention to when you are going to eat something (sweet or not), and sit down and make a little event of it. For example, you could grab some tea or coffee with something sweet, take out just a piece and put back the rest, and really sit down and enjoy it and pay attention to what you are eating. If you slow down like this you might be less likely to eat as much of it.
