If an adolescent were to take part in moderate exercise it could form part of obesity treatment, according to a new study.
The research stated that adolescents who suffer from obesity often have pancreatic problems, as it must produce added insulin to maintain blood-sugar levels in the body.
It is claimed in the report, conducted at the Baylor College of Medicine, that moderate exercise could improve the body's sensitivity to insulin, even if no weight loss is achieved.
Dr Agneta Sunehag, lead author of the article, said: "We found that a 12-week moderate aerobic exercise program consisting of four 30-minute workouts a week increased fitness and improved insulin sensitivity in both lean and obese adolescents."
She also pointed out that many studies involve diet and exercise variants, but that this one focused only on the latter.
The study is set to be published in the Journal of Clinical Endocrinology & Metabolism, which is ranked 11th out of 93 different publications covering the study of endocrinology and metabolism.
