Weight Changes and Weight Cycling
Weight Loss Study Aim
To evaluate the influence of recent weight changes (weight gain, loss
and cycling) on subsequent weight changes.
Weight Loss Study Subjects
A total of 18 001 non-smoking subjects, 6689 men and 11 312 women, from
the general population.
Weight Loss Study Measurements
Body height and weight measurements and interview data on lifestyle habits
and medical history at baseline. For follow-up, self-administered questionnaires
for assessment of body weight and incident diseases.
Weight Loss Study Results
Recent changes in body weight, that is weight gain, weight loss and weight
cycling, were significant predictors of subsequent weight changes in both
men and women after controlling for age, baseline BMI and several lifestyle
and behavioural characteristics as potential confounding factors. Weight
cycling before baseline was the strongest predictor of subsequent large
weight gain (2 kg) with an odds ratio (OR) of 4.84 in men. In women, prior
weight loss was the strongest predictor of subsequent large weight gain
followed by weight cycling.
Weight Loss Study Conclusion
These data indicate the need for thorough weight history assessment to
identify those who are most likely to gain weight. Effective weight control
before the development of obesity or after intentional weight loss due
to obesity should be a primary goal in the management of obesity.
