Overweight or obese children who lose the excess weight by adulthood have a similar cardiovascular risk profile as adults who were never obese, according to a study in the New England Journal of Medicine. Using data from four prospective cohort studies, researchers followed more than 6000 subjects from roughly 11 years of age until they reached their thirties.a
As expected, subjects who were overweight or obese in both childhood and adulthood had significantly increased risks for type 2 diabetes, hypertension, dyslipidemia, and carotid-artery atherosclerosis, compared with adults who were never obese. However, subjects who were overweight or obese in childhood and then became nonobese as adults had similar risks as those who were never obese.
Therefore, it is never too late to change your lifestyle habits.
