Depends: Great question! Because of the ways that calories are stored (eg, sugars are converted to fats) - a lot depends on your body composition, metabolism, basal metabolic rate, and other factors. If you have concerns about your diet - I'd suggest seeing your doctor or a clinical nutritionist for help. Good luck!

Cold weather wt loss: If you are "cold" and do not wear appropriate clothes for the climate. The answer is a qualified "yes"; a few more but not significant enough to try nudity in the arctic as a weight loss plan. Frostbite could kill you. On the other hand, if you are more active in the winter-ski snowshoe, snowboard, shovel snow and don't compensate with more food, you can lose weight and become more fit.

Do you burn more calories if you are thin?

Possibly: All things being equal (same caloric intake) - thin people tend to waste calories, thus burning them up with less contribution to body mass, while heavy people tend to be effecient users of calories, wasting less and adding to their body mass. In times of plenty, efficient users become fat. In times of scarcity efficient users survive while calorie wasters starve to death.

Don?T understand what activities burn the most calories?

Activities that...: Inrease your heart rate the most. Since muscular fatigue is a limiting factor as well, the more muscles engaged in sporting activities seem less strenuous that they really are. These would include rowing a cross country skiing, an eliptical trainer, schwinn air dyne, etc. But resistance activities have "hidden" burn, since your muscular growth will consume caslories after exercise.
