I have to admit, I have been doing intermittent fasting for many years. I usually stick to an 18/6 plan, in which I eat all my daily food within the 6 hour window and fast for 18. I have also pretty much done away with sweets, most carbs (no pasta, bread, white foods, etc.), and not only do I not crave them at all, I feel more emotionally stable since switching to this style of eating and have experienced this increased stability from very early on. Aside from controlling my weight and numbers, this was not what I was seeking, but did find it to be very real once I committed to it, and it was very pronounced. I add this because I wouldn't have believed it until I experienced it, and it really has been a great revelation for me and something that I share with people if given an opportunity.
