The mean amount of weight lost over the eight weeks was nine kilograms, but did not differ between groups. The strength-training group showed increases in flexed arm muscle mass and grip strength. Mean resting metabolic rate dropped significantly in all groups. Strength training significantly preserved lean tissue relative to aerobic training, or no exercise, in those dieting without conserving resting metabolic rate. The protective effect for lean tissue was a major advantage of strength training, pointed out the researchers.
Most people gain weight when they hit middle age.
That's what researchers at the American Cancer Society in Atlanta wanted to know. The researchers compared the 25,000 or so who didn't gain weight to the 50,000 or so who did. Weight gain was more likely in people who ate red meat more than three times a week. The research team also found that they tend to be protected against weight gain in the abdomen. Where one gains weight matters.
