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.

For every study that shows them inextricably linked, another found no relationship at all ... or even an inverse
relationship, where skipping breakfast led to weight loss. Read the rest
The New York Times has a fascinating story about the current state of the science on weight loss, including the results of one recent (albeit small) study that suggests that the human body responds to weight loss by actively trying to regain weight—a finding that could help explain why it's so difficult to maintain significant weight loss, even when you are able to shed pounds.
