Relation between self-reported weight cycling history, dieting and bio-behavioral health in Japanese adult males

Abstract

Background: Epidemiological findings suggest that weight fluctuations are associated with unfavorable health outcomes compared with stable weight. However, the interrelationship between the weight cycling history and dieting status in a non-clinical male trial on the risk for bio-behavioral health is unclear.Objective: The purpose of this study was to examine the relation between weight cycling history as a result of intentional weight loss and bio-behavioral health in Japanese adult males.Method: A cross-sectional study was performed on a group of 146 Japanese working males (47.5H9.3 yr.). Each subject completed a series of self-reported questionnaires in which information about weight cycling history, current dieting practices, life-styles, and social background were assessed. Results of the physical check up were used to assess biological parameters. Self-reported weight cycling was defined as intentionally losing 10% of one's weight and regaining the lost weight.Results: Cyclers reported a significantly greater incidence of current dieting and recent weight gain compared with non-cyclers. Taking regular meals, eating breakfast everyday, and not eating snacks between meals every day were significantly less frequent among cyclers compared with non-cyclers after controlling for BMI. The adjusted odds ratio for AST abnormality was 5.46 (95%CI: 1.08−27.67), ALT abnormality was 3.31 (95%CI: 1.24−8.78), and 1-GTP was 3.38 (95%CI: 1.07−10.67) among cyclers, compared with noncyclers.Conclusion: These findings suggest that a history of weight cycling in men, regardless of current weight status, is associated with adverse bio-behavioral health. The risk for several liver enzyme abnormalities associated with weight cycling history was substantial, independent of relative body weight and lifestyle factors.

“…Other studies conducted in university students exercise stages of change are more clearly identified the higher exercise stages of change level in men than their women counterparts (Wallace et al, 2000;Wakui et al, 2002;). A related finding was found in the study of Suminski and Petosa (2002).…”

“…Previously, exercise stages of the changes have been studied with different population in many countries around the world, including United States, Canada, Australia, United Kingdom, 15 European Union countries, the Netherlands, China, Malaysia, Japan, and Mexico.

Atherosclerosis and cardiac function assessment in low-density lipoprotein receptor-deficient mice undergoing body weight cycling

“…Although there is controversy in the literature about whether or not yo-yo dieting can lead to problems involving gall bladder and liver, 15, 38 data are overall supportive that weight loss decreases risk factors associated with major diseases such as cancer. 39 With respect to cardiovascular diseases, there is still controversy based on the idea that weight cycling, particularly in younger individuals, may result in fluctuations of heart rate, blood pressure, sympathetic activity, glomerular filtration rates and circulating glucose and lipid levels that may alter heart development and/or cause lipotoxic events influencing cardiac function.…”

“…7, 8, 9, 10, 11, 12, 13, 14, 15, 16 Some studies find increased health risks associated with weight cycling, while others do not. A major drawback of these studies is the lack of consistency in the definition of weight cycling.…”
