They then compared those numbers with the same measures for an average male and female Westerner. The statements suggest that to optimize weight loss, a combination of diet and exercise is best, and that exercise alone will not suffice. They conclude that if these factors were equal, exercise alone can be as effective as caloric restriction for weight loss. To better understand why, anthropologists leading one of the new studies began with a research trip to Tanzania. The second statement claims that physical activity, without caloric restriction, minimally if at all affects fat loss. To achieve this degree of weight loss, women decreased their average caloric intake by 945 kilocalories a day while the men decreased their average intake by 1705 kilocalories a day.

They also asked them to swallow so-called doubly labeled water, a liquid in which the normal hydrogen and oxygen molecules have been replaced with versions containing tracers.

(2000) report that few randomized control trials equally compare diet only to exercise only weight loss programs. The first statement declares that the addition of exercise to a diet with restricted caloric intake promotes fat loss, while maintaining fat free mass. 28, No. Exercise and Sport Science Reviews, Vol. But it was not true that they were burning far more calories. In an attempt to define the role of exercise in the treatment and prevention of obesity, the American College of Sports Medicine (ACSM) held a scientific roundtable to address this subject. 165-170. 4, pp. It is estimated that 55% of the adult population in the United States are either obese or overweight (National Institutes of Health, National Heart Lung, and Blood Institute, 1998). And it was true, the scientists determined, that the Hadza people in general moved more than many Americans do, with the men walking about seven miles a day and the women about three. The overarching conclusion of that study, which was published last week in the journal PLoS One, is not really new or surprising, says Dr. Two groundbreaking new studies address the irksome question of why so many of us who work out remain so heavy, a concern that carries special resonance at the moment, as lean Olympians slip through the air and water, inspiring countless viewers to want to become similarly sleek.
