Should I eat less?

Really depends on how much you're eating on a daily basis. If you've stayed at the same weight for a period of time, it's really unnecessary to cut your diet to lose body fat. All you have to do is burn more calories than your body absorbs and you're on the right path to weight loss (well actually body fat loss to be accurate). Thats as simple as it is. You might see a gain in weight if you do this, but it's really muscle gain. And more muscle mass means more calories burnt even when you're not doing much. Of course the fastest way to lose body fat is to combine exercise with dieting. But I for one love food too much to do that. However, if you intend to exercise while dieting, do keep some things in mind. When you've just started an exercise routine, give it some time before starting dieting as well. Your body is already under additional stress from working out. You don't want to make it work overtime with lousy wages right from the start. Let your body get used to the additional workload, then slowly ease into it.
