Much has been written and reported about the growing prevalence of obesity, including in children and teens. So, it may be encouraging that a global review of studies shows many teens are trying to lose weight. The problem is how they are going about it. In the review of more than one-half million teens, nearly one in ten turned to non-prescription weight loss products. The study, in JAMA Network Open, notes the products tend to be ineffective and with potential long-term health consequences. Given those scenarios, the researchers at Monash University School of Public Health recommend interventions to reduce use of weight-loss products among teens.
