Targeted ablation of glucose-dependent insulinotropic polypeptide (GIP)-producing K cells in mice prevents high-fat diet-induced obesity and insulin resistance by reducing body weight, decreasing food intake, and increasing energy expenditure.

This preclinical study suggests that blocking the action of GIP-producing cells in the gut can protect against obesity and insulin resistance caused by a high-fat diet. The mechanism involves reduced food intake and increased energy expenditure. While this is not a human intervention, it highlights GIP as a potential therapeutic target for obesity.
