How sugar leads to you stuffing your face

Ready to start the New Year off right? Then STOP obsessing over fat... STOP counting calories... STOP worrying about how much meat you're eating and finally START the one diet that can chase away the pounds, prevent diabetes and protect the brain and heart at the same time.

It's the high-fat, low-carb diet, of course. And new research proves -- AGAIN -- that the fats in this great-tasting healthy lifestyle don't lead to overeating.

It's sugar.

Sugar lights up the reward center of the brain in ways that fats never can despite the fact that fats are, when it comes down to it, far more delicious.

After all, what would you rather have: bacon, or a lollypop?

I rest my case.

In the new study, more than 100 healthy teens were given milkshakes with varying levels of fats and sugars as their brains were scanned. Fat content almost didn't matter. What did matter was sugar: the more sugar in the shake, the crazier the brain's reward center went.

The biggest burst of activity came with a shake loaded in sugar, but relatively low in fat. The putamen, insula and rolandic operculum lit up like the Times Square ball on New Year's Eve.

Together, these three parts of the brain make up the food reward system -- or the part that causes you to eat, eat, eat until you burst, burst, burst.

The researchers tried upping the fat levels in that high-sugar shake, but the extra fat didn't make a difference at all.

Just the sugar. And that, folks, is why people overeat: SUGAR.

This study focused on pure sugar, but all carbs have a similar effect, leading to cravings, hunger, overeating and eventually weight gain and obesity. Fats, meanwhile, do the opposite -- leaving you feeling full and satisfied and far less likely to overeat.

So this year, make a resolution you can keep. Finally start a low-carb diet of your own and watch the pounds melt away.

Step one: Toss the margarine and stock up on butter.
