You could also try intermittent fasting. Perhaps a 15 hour fast several times a week. That's pretty painless. Don't make up for it later. Or, try a 23 hour fast. Apparently these kinds of short fasts have healing qualities beyond just the reduced calories of eating less. The trick is, if you can do a fast like this without difficulty, it can only help. If you struggle with a lot of hunger, don't do it. You aren't ready yet.
