You can buy natural, no sugar added brands at almost any grocery store now. Each chain store has its own brand-name version. The natural stuff is better because there are no hydrogenated or partly hydrogenated fats. It's just peanuts.

I have read that a tbsp when you are hungry is good for curbing hunger pangs and cravings. PB has a good ratio of fat and protein. Even though it does have some carbs, some of them are fibre.

I ate PB and lost weight. You can always add some splenda if you like it sweeter. There are also recipes for low carb PB cookies on this site.

Try it and see-- just remember that it is high in calories so you can't gorge on it. Just be careful and monitor your progress.

I am a PB lover too, hence the name. (I buy an organic just peanuts kind at the grocery store.)
