Exercise - a combination of aerobic and strength training is more effective for weight loss

Researchers have found that doing just aerobic exercise (jogging, swimming, fast walking etc) or just strength training (weights) is not nearly as effective at helping you lose weight as a combination of the two.

The 16 week study (1) examined fifty sedentary but healthy men, average age 25. They were divided into four groups - a control group that did not exercise, a group that did aerobic exercise, a group that did weight training, and a group that did both forms of exercise.

The group that combined weight training with their aerobic exercise ate significantly fewer calories than those who did either aerobics or weight training alone, or those who did no exercise at all. The researchers found that the combined exercises had the best effect on blood sugar and fat levels. Importantly, this group also felt less hungry - their bodies were able to generate satiety hormones.

Usually, when people lose weight by doing exercise, they feel a little hungrier, and compensate by eating more. (2) But this study showed that the group doing both forms of exercise did not feel hungrier, so the benefits were not lost.

In Grow Youthful I explain that there are three main types of exercise - aerobic, strength, and stretching or flexibility, and why we need a combination of all three for long life.
