Resistance exercise has been increasingly recognized as a crucial component in preventing diabetes and obesity. According to a study published in the Journal of Applied Physiology, resistance training can improve insulin sensitivity, reduce — fat, and enhance glucose metabolism (1). This is particularly significant, as diabetes and obesity are two of the most pressing public health concerns globally, with the World Health Organization (WHO) estimating that 422 million people worldwide suffer from diabetes, and 1 billion people — with obesity (2). The benefits of resistance exercise in preventing diabetes and obesity are multifaceted.
For instance, a study conducted by the American College of Sports Medicine (ACSM) found that resistance training can increase muscle mass and strength, which in turn can improve glucose uptake and insulin sensitivity (3). Resistance exercise has been shown to reduce inflammation, a key factor in the development of insulin resistance and type 2 diabetes (4). In addition, a study published in the Journal of the American Medical Association (JAMA) found that resistance exercise can also improve cardiovascular health, reducing the risk of cardiovascular disease, a common comorbidity with diabetes and obesity (5). Experts recommend that adults engage in regular resistance exercise, aiming for at least two to three sessions per week, targeting all major muscle groups (6).
