When your body gets cold, your metabolism cranks up. You burn more calories. Thin Ice is making vests, shirts, and insoles containing battery-powered Peltier plates, which become cold when current passes through them. You can control the cooling system with a phone app. The manufacturer estimates that you can burn between 500 and 1000 calories a day wearing the clothing.
The flaw with Thin Ice is that being cold makes you hungry. Your brain will demand food to replace the calories you are burning. Diets don't work if you are hungry all the time. Rob mentioned earlier today that a low carb diet has helped him lose weight. I've been on a low carb diet for almost five years and my weight has stayed down, and I rarely get ravenously hungry.
