Exercise in Early Teenage Years May Reduce Diabetes Risk

Early physical activity in adolescence has been linked to lower insulin resistance, a precursor to type 2 diabetes, according to a study led by the University of Exeter. The research found that exercise provides significant benefits to insulin resistance at age 13, but this benefit diminishes by age 16. Health experts emphasize the importance of targeting early teens for reducing diabetes levels, particularly as type 2 diabetes is linked to increasing levels of obesity, unhealthy diets, and a lack of exercise.

Key Takeaways:

• A study by the University of Exeter found that physical activity in early teenage years reduces insulin resistance, a precursor to type 2 diabetes.
• Insulin resistance was 17% lower in more active adolescents at age 13 independently of body fat levels.
• The benefit of exercise on insulin resistance diminishes progressively over the next three years, disappearing completely by age 16.
• Researchers suggest targeting early teens specifically for reducing diabetes levels.
• Dr. Brad Metcalf, from the University of Exeter's School of Sport and Health Science, highlights the importance of physical activity for overall health, regardless of age.
• There are 3.9 million people in the UK with type 2 diabetes, linked to unhealthy lifestyles, obesity, and lack of exercise.
