For other uses, see Jack Frost (disambiguation). Jack Frost is the personification of frost, ice, snow, sleet, winter, and freezing cold. He is a variant of Old Man Winter who is held responsible for frosty weather, nipping the nose and toes in such weather, coloring the foliage in autumn, and leaving fern-like patterns on cold windows in winter.
Dear Countin' Cal, Theoretically, about 3500 calories equals one pound of body weight. This means that you'd have to take in 3500 fewer calories than you usually do, over a period of time, to lose one pound. Keep in mind, this is in theory; what happens in the real world can be very different.
In order to average one pound per week it would be necessary to burn an additional 500 calories per day. (7 days a week X 500 calories per day = 3500 calories.) If you do not have the time or energy to burn the additional 500 calories a day you can use a combination of calorie reduction and exercise.
