The answer to weight loss is net calorie intake. Net calorie intake is the amount of calories a person consumes minus the amount they burn in a given time period. This means the amount of weight loss a person experiences is only relevent to exercise when also compared with the amount of calories consumed.

A study published online in September in The British Journal of Sports Medicine was the latest to report apparently disappointing slimming results. In the study, 58 obese people completed 12 weeks of supervised aerobic training without changing their diets. The group lost an average of a little more than seven pounds, and many lost barely half that.

The study also looked at indirect effects that exercise would have on weight loss. It found that the phenoninom "afterburn," where the body continues to burn fat calories after excercise, had no effect on the subjects in the study.
Also included in the study was the ideal heart rate for fat burning. It was found that the ideal intensity for fat burning is 105 to 134 beats per minute. That is likely a very light job or very brisk walk. The higher someone would work in that zone the more calories of carbohydrates one would burn so the mroe total calories burned.

So the answer to weight loss is the combination of excercise of any sort and calorie reduction.
