Weight Cycling - Psychological & Physiological Effects
The US National Task Force on the Prevention
and Treatment of Obesity evaluated the psychological and physiological
hazards of dieting and repeated weight loss and regain (weight cycling
or "yo-yo dieting"). A systematic review published in 1994 found
no evidence that weight cycling has adverse effects on body composition,
energy expenditure, risk factors for cardiovascular disease, or the effectiveness
of future attempts at weight loss. Another systematic review found no
evidence that dieting induces eating disorders or other psychological
dysfunction in overweight or obese adults. The task force has concluded
that concerns about these possible harms do not outweigh the potential
benefits of weight reduction.
