'Werewolf diet' attracts celebrities, critics

PHILADELPHIA - February 26, 2014

And I have to agree with that.

It's called the "Werewolf Diet." Celebrities such as Madonna and Demi Moore have reportedly followed it.

It all centers around the phases of the moon.

Like the werewolves in the "Twilight" movies, the 'Werewolf diet' claims to help you get lean and mean.

Howling at the moon is optional.

The premise is to eat according to phases of the moon. The idea is just as the moon influences ocean tides... It can also influence how your body flushes toxins.

The basic plan says on a new or full moon, you'll fast for 24 hours, only drinking water, or fresh fruit and vegetable juice.

In the extended version, as the moon wanes, you eat a balanced diet and drink at least 8 glasses of water per day.

During the waxing moon, you should eat less, avoid sweets and don't eat after 6 p.m.

I asked Dr. Charlie Seltzer, a board-certified obesity specialist who operates the Limitless Longevity clinic in center city for his opinion.

He calls it ridiculous!

"It's another fad weight loss gimmick that's going to be ineffective in the long run and is based on no science," he told us.

The Werewolf Diet says you can lose two to 6 pounds during the fasting period. But -

"The weight loss you get in these programs is all water weight," he said.

"True fat loss is a lot slower process and it's basically physiologically impossible to lose 6 pounds of fat in a day," he continued.

So even if you lose 6 pounds, as soon as you break the fast, you will gain it back.

There is some research showing that intermittent fasting can help you live longer. However, that's over a lifetime.

As for the extended version of the diet, Dr. Seltzer says,"There is no scientific evidence that planning nutrition around the phases of the moon will result in any more weight loss than if one did a program not related to the phases of the moon," he notes.

So once again, there is no such thing as a quick fix for weight loss.

The best way to lose weight is to maintain a healthy diet - and exercise.
