Professor Ben Bikman discusses sarcopenic obesity, a condition involving obesity and muscle loss. This condition results from factors like sedentary lifestyles, aging, and metabolic disturbances. While obesity is common, sarcopenia typically affects the elderly, diseased, or very sedentary individuals. The combination of excessive fat and muscle loss makes sarcopenic obesity particularly challenging.

Dr. Bikman explains the crucial role of muscle in blood glucose regulation. Muscle mass reduction impairs glucose control, leading to higher blood sugar levels and increased insulin resistance. Even a short period of bedrest can significantly reduce muscle mass and insulin sensitivity. Inflammation from enlarged fat cells also contributes to muscle loss and insulin resistance, creating a vicious cycle.

Insulin resistance and sarcopenic obesity can both cause and result from each other. Insulin resistance impairs muscle protein synthesis and promotes fat cell growth, leading to further insulin resistance. Reduced muscle mass and increased fat cell size negatively impact metabolic health. Bikman stresses the importance of diet in managing sarcopenic obesity, advocating for a lowinsulin diet by controlling carbs, prioritizing protein, and not fearing fats.

To combat sarcopenic obesity, Dr. Bikman recommends proper nutrition and resistance training. Reducing insulin levels helps preserve muscle mass and promote fat loss. Resistance exercise is more effective than aerobic exercise for improving metabolic health. Consistent exercise and a controlled diet can help individuals manage or prevent sarcopenic obesity and improve metabolic health.
