The two diet groups received counseling as well as all foods provided. This "weight loss" period was followed by another six months of "weight maintenance" and observations.

Both diet groups lost about 5. At the end of the 12 months, there was only one difference between the two diet groups: the alternate fasting day group had a significant elevation in low density lipoprotein LDL , an increase of LDL is known as a risk factor for heart attacks and strokes, so that's not good.

Twelve people quit the alternate-day fasting group, with almost half citing dissatisfaction with the diet.

From apples to zucchini, there are over a hundred "real" foods you can eat endlessly, enjoy, and yes, still lose weight.

I would advise against spending any more money on fad diet books. Or processed carbs, for that matter. Rather, hit the fresh or frozen produce aisle, or farmer's market, and go crazy. Then go exercise.

Do that, say, for the rest of your life, and you will be fine. No one got fat eating broccoli, folks. That said, if you tend to binge or stress-eat sugary or starchy foods, and you feel like you can't control your habit, talk to your doctor, because that is a separate issue to be addressed.
