Yes, insulin resistance can make weight gain easier—especially promoting abdominal fat accumulation. Insulin is a hormone that supports fat storage. When resistance develops, the pancreas produces more insulin, and chronically high insulin levels can make fat loss harder. Many people experience the “I eat less but cannot lose weight” pattern. Glucose swings can also increase cravings and snacking, making calorie control more difficult. The solution is not only cutting calories, but reducing insulin-spiking food patterns, building protein and fiber structure in meals, and increasing walking plus muscle activation. Weight management is both a consequence and a solution: as waist circumference decreases, insulin sensitivity tends to improve.
