Optimizing exercise for fat loss.

Author information

Nutrition 21, San Diego, CA 92109, USA.


From the standpoint of promoting fat loss, the chief benefits of aerobic exercise are attributable to fat oxidation during exercise and a post-exercise reduction of respiratory quotient. The ability of exercise to selectively promote fat oxidation should be optimized if exercise is done post-absorptively (preferably during morning fasting metabolism), if caffeine and possibly hydroxycitrate/carnitine are administered prior to exercise, if the exercise regimen is of moderate intensity and prolonged duration, and if no calories are ingested for several hours following exercise. A simple mathematical model is presented which delineates the factors that determine daily fat balance during exercise training. This model clarifies the crucial importance of low-fat eating if exercise is to have an optimal impact on fat stores. As a complement to aerobics, resistance exercise can benefit dieters by helping to preserve lean mass and metabolic rate in the face of a persistently negative caloric balance.
