A team of researchers has examined the effect of exercise on fat accumulation in five obese women. In one session the women overate and did not exercise; in a follow-on session they overate and did exercise. The researchers found that: the body’s fat-burning oxidation rate was reduced after one day of overeating; Just one session of exercise increased the rate of fat-burning oxidation; and exercise increased the amount of fat that would eventually be stored in the muscle.
