A couple of day's ago I was surprised to see how effective the Peanut Butter Diet was.
I also did some online research into this diet and it looks like it may even be beneficial for heart health as it boosts 'good' cholesterol.
I think if you really struggle with sugar cravings, this diet may be worth considering. In my case I have been avoiding having the peanut butter with carbohydrates such as toast. I am having it mixed with some Greek style yoghurt, with fruits such are apple/pears or with steamed (microwaved) savoy cabbage leaves. I am finding that I am staying fuller longer and don't crave any other snacks.
I am just having two helpings of peanut butter a day for now and can notice my appetite has been curbed effectively. I will definitely continue with this diet as peanut butter doesn't feel like diet food!
