Part 3/14:
People with insulin resistance find it particularly difficult to shed excess fat. When insulin levels are elevated, the body's capacity to burn fat diminishes because insulin acts as a storage hormone—encouraging the body to retain fat rather than break it down. After events like a vacation or indulgent eating, individuals tend to gain weight rapidly, often 5 to 10 pounds, due to insulin-driven fat storage.
The key to effective weight loss in these cases lies in modulating insulin levels. Simply reducing caloric intake, a common approach, isn't sufficient and can sometimes slow down metabolic rate, leading to muscle loss alongside fat. Instead, fasting emerges as a potent strategy because it directly lowers insulin, prompting the body to tap into fat stores more efficiently.
