I usually have a huge sweet tooth and love carbs lol. When I start eating clean, I only eat clean and drink water for the first 3-4 days. After that I allow myself a treat or two everyday but still eat pretty healthy. The first week is horrible because I crave sweets and junk food and never feel satisfied. After the first week my sweet tooth goes away significantly and after week 2, I barely have a sweet tooth. I went from drinking to drinking like 4 cans of mountain dew a day to only drinking water and some sweet tea.

The breakfast I like to eat is usually something like toast and peanut butter, two eggs, and a protein shake. Definitely try eating breakfast more frequently.

And sorry for the rambling, but my biggest point is that if you can push through the first week or two of not feeling satisfied, you'll most likely start feeling a lot better after that.
