from the health section of the new york times we read:
Duration and intensity of physical activity are important factors in how much fat the body burns for energy, which, after all, is what you want to lose. The harder and longer you work out, the more fat you will shed.
When you diet without exercising, you lose both muscle and fat, which is counterproductive because muscle loss significantly lowers your basic metabolic rate, the number of calories your body uses at rest.
Type of Activity Matters
Weight-bearing activities that work against gravity — aerobic activities like walking, running, cross-country skiing, dancing, skating and stair-climbing — use proportionately more calories at a given level of effort than swimming, cycling or water aerobics.
The more muscle groups involved in your activities, the more calories you are likely to burn. That is why working out against gravity uses more calories than non-weight-bearing activities.
