Abstract
After reviewing studies on weight cycling, we concluded that methodology left much to be desired and that the following matlers should be taken into reconsideration :
1. There is as yet no established definition of the term “weight cycling”. Consequently, different definitions of weight cycling are used in different studies.
2. The definition of weight cycling lacks any standard. Consequently, different criteria of weight change are used in different studies.
3. Weight cycling is assessed by cycles of loss and regain of body weight. For the purpose of elucidating the correlation between weight cycling and health body weight is preferable to BMI as a weight change variable.
4. Providing a relevant measure for weight cycling encompasses many components. The body weight collected by direct measurement is most reliable. However, an interval of measurement of body weight differs in different studies.
5. In light of the standards of population-based epidemiological research, the studies are generally of small-to-modest size.
6. Few studies have been able to differentiate between intentional and unintentional weight changes.
