Weight cycling in adulthood may lead to fragile bones later in life, according to a new study of 4 601 men followed for 28 years.
How the study was doneIn the current study, in the American Journal of Epidemiology, the researchers investigated whether weight cycling was related to the risk of forearm fracture, "an early and sensitive marker of male skeletal fragility."
Sogaard and her team had previously found that among the group of men initially examined in 1972-1973 and then later in 2000, those who had lost weight more frequently, and lost more weight with each slimming bout, were more likely to develop metabolic syndrome and diabetes.
Diet and dieting play important role too
People who want to make sure their bones stay strong when they lose weight should always be sure to exercise as well as diet, Sogaard said. "We know that weight-bearing activities, weight-training and exercise with varied loadings (e.g. squash, badminton, tennis) are favourable for muscles (and) balance, as well as bones."
