 Looking for a diet that will help you burn the fat? Consider the chilli. Because ? the chemical compound that gives chilli peppers  their kick, appears to prevent weight gain in mice that are  fed with a high-fat diet. The finding was presented at the Biophysical society's annual meeting in Baltimore. Obesity is caused by an energy imbalance, more calaries go in than go out. So conventional wisdom has it to tip the scale the other way; You could eat less, or move more. But maybe there's the third option. Researchers treated mice a diet high in fat. But some mice also got a pinch of capsaicin. After twenty-five weeks, the mice with added spice gained less weight than those on fat alone, even though they ate and drank the same amount. Since the mice that got the ? treatment were more likely to get off their rodent wheels, they naturally spent more time exercising than their fat-fed counterparts. But before you stock up on chilli-flavored chittos, keep in mind that mice eating a well-balanced diet in the first place were the most active and sleek. So feel free to use your ? But maybe skip the chips.
