Your Bum Muscles Could Predict Diabetes

Recent scientific findings reveal a connection between the composition of the gluteus maximus muscles and the likelihood of developing type 2 diabetes. The study, which analyzed MRI scans, focused on intramuscular fat—fat within the muscle tissue, analogous to marbling in steak—rather than visible subcutaneous fat. This internal fat accumulation is linked not only to diabetes but also to other metabolic diseases like cardiovascular and liver conditions, and even mortality.

Frailty is strongly associated with increased intramuscular fat, leading to a higher risk of falls and loss of independence. Conversely, higher fitness levels correlate with healthier muscles. The research, using data from the UK Biobank, indicates that muscle mass declines notably even over short periods, suggesting a need for consistent physical activity. Strength training is particularly effective, with studies showing it can reduce diabetes risk by 17% to 30%.

Experts recommend regular strength training, including compound exercises, with two to three sessions per week. Activities like walking, cycling, and high-intensity interval training (HIIT) are also beneficial for maintaining muscle quality and improving glucose metabolism. While MRI scans are the only way to accurately measure intramuscular fat, making it impractical for widespread screening, these findings underscore the profound impact of muscle health on overall well-being and disease prevention.
