How to lose weight and keep it off -- for good!

It happens so often that doctors have a name for it: the yo-yo.

But unlike the children's toy, this one's no fun at all.

The yo-yo is what happens when you got on a diet... lose a bunch of weight... and quit the diet because you think your work is done.

In physics, what goes up must come down. But when it comes to the yo-yo diet, it works the opposite way: What goes down usually comes right back up.

Next thing you know, you're standing on the scale wondering where you went wrong -- because not only did you regain the weight, but you actually tacked on a few extra pounds to boot.

It's so frustrating some folks just about give up -- and those who try again often find it even harder to lose weight after it's come back.

But today, I'm going to let you in on a little secret.

New research reveals the key to losing weight, keeping it off, and never having to play a game of yo-yo with your body.

This secret isn't just in what's on your dinner plate.

It's on the calendar -- because you have to wait 12 months before you can consider weight loss a done deal.

Once you lose weight, your body seems to think there's something wrong. It's as if it "remembers" your old weight and will fight to get back there.

As a result, the new study finds that the hormone levels that help regulate your weight and appetite resist your new lower weight -- and they keep resisting for a year.

The "hunger" hormone ghrelin, for example, increases right after weight loss. It sends a signal that you're hungry so you eat to regain weight.

It thinks it's trying to help!

Of course it's not. It's actually making your weight loss harder.

Fortunately, it gets the message -- eventually. After a year, your body's hormones will "reset" so they're no longer telling you to eat to regain weight.

The obvious key here is to create a two-part goal when it comes to dieting.

Set a weight... then set a date.

Diet for a few weeks or months, however long it takes to reach your goal, and then keep watching your food -- and your waistline -- carefully for another year.

You'll be locked in at your new weight, and it'll be a little easier to maintain it and make sure you don't regain it.

Just don't let your guard down; it's all too easy to slip back into old bad habits.

And if you're looking for the safest and most effective way to lose weight, keep it off and get healthy all at the same time, I've got a simple back-to-basics diet that's guaranteed to work for you -- and you can read all about it in this free report from my House Calls archives.
