Optimizing exercise for fat loss.
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.
