BODY weight can fluctuate for a variety of reasons, one of which is dieting with the goal of weight reduction and the subsequent regaining of the weight that was lost. Because repeated episodes of weight loss and gain are so common, it is important to examine the implications for health of this pattern, which we refer to as weight cycling. The results of a study of employees of the Western Electric Company indicated that a single cycle of weight gain and loss in men was a risk factor for death from coronary heart disease, but not for death from all causes.1 The Gothenburg Prospective Studies found that variability in body weight measured at three time points was a risk factor for subsequent coronary heart disease in men and for total mortality in both men and women.2 In contrast, no significant associations between fluctuations in body weight and mortality were detected in two other cohorts.3 , 4 Three of these studies1 2 3 were limited by the fact that only a single cycle of weight fluctuation was represented in the indicators of variability of body weight used by the investigators.

These studies demonstrate the importance of investigating further the associations between fluctuations in body weight and health, and they underscore the challenges of doing such research. In overweight persons, voluntary weight reduction is assumed to be beneficial to health, whereas involuntary weight loss often reflects serious disease. Conversely, weight gain may lead to obesity and its concomitant adverse effects, yet some increments in body weight occur normally in healthy persons as they age. Fluctuations in weight that precede disease must be distinguished from those caused by disease. We addressed these issues by studying the associations between the degree of variability in body weight and subsequent health outcomes in subjects participating in the Framingham Heart Study.

Dear ladies,

I like your title but you failed to point out the main idea. I think you mean the supporting details instead of the main idea. Please see me to discuss this again with you.

Please try to define some words that are difficult to understand such as: fluctuate, dieting, reduction, overweight, others.

Enjoy reading!
