Significant weight loss achieved through very low calorie diets (VLCD) or bariatric surgery can preserve and enhance beta-cell function in type 2 diabetes, particularly in patients with short disease duration.

If you have Type 2 Diabetes, especially if diagnosed recently, significant weight loss is the most effective way to restore your pancreas's ability to make insulin. This can be achieved through bariatric surgery or a strict 600-calorie daily diet for a short period (1-8 weeks). This is not just about weight loss; it is about 'resting' the beta-cells to restore their function.
