One of my favourite bits of research on exercise though comes from the Biogenic Diet Book by Leslie Kenton: I think it sums up all we need to really know
Burn Fat Not Sugar - when you exercise there are three ways you can use energy: you can call on glycogen or sugar stored in the muscles, you can call on glucos - sugar stored in the blood; or you can call on free fatty acids which you get either from triglycerides stored in the body or from burning fatty tissues via the mitochondria.
Which route you use to feed your movements depends on the intensity of the effort you are making in your exercise. Using exercise to enhance body ecology and thereby both to decrease cellulite and to rejuvenate demands low intensity. Why? because low-moderate intensity isotonic movement develops red not white muscle fibre and burns fat best. It utilizes free fatty acids first and only second does it turn to muscle glycogen as food. That is exactly what you are after in breaking down cellulite as well as in shedding ordinary fat from the body. You want to stimulate the mitochondria of your cells to release fatty acids, turning them into energy and enhancing metabolic processes at a cellular level. If you are overweight this will mean you get maximum support for the burning of stored fat and for turning flabby low energy tissue into firm strong muscle.
If you go the other way with exercise, pushing yourself to the limit you will defeat your efforts - as aerobic exercise increases, more white fibres develop and the burning of glycogen becomes more important than the burning of fat. At 80% of your exercise limit glycogen supplies twice the energy that fat free fatty acids do. At 100% it supplies virtually all. Pushing yourself to your limits only make worse the disturbances in your body's ecology which produced cellulite in the first place. It also produces large quanitites of lactic acid creating acidosis, which increases your bodily pollution (which is why a few top women athletes can't shift their cellulite). So exercise to banish fat needs to be rhythmical and continuous, using large muscle groups and performed at an intensity and frequency that increases your heart output only to 60% of maximum heart rate - never more.
Just as working too hard is counterproductive so is working too long. Exercise done properly will energize, not exhaust you. If an hour after a session yu feel a lot of fatigue that is a sure sign you have been pushing too hard. Your body has probably been burning sugar rather than fat and in the process producing clinkers of waste. There is no ideal time limit for this exercise; it all depends upon your current fitness level. 15 minutes may be all you need to start off with; others may need 60 minutes; remember; if you are energised not fatigued it is the right amount for your body. If you exercise in this way you will begin to experience an abundance of life force and creativity and it is the start of caring for yourself!
