Intestinal deficiency of Acyl-CoA synthetase 5 (ACSL5) reduces food intake and protects against diet-induced obesity by increasing postprandial secretion of GLP-1 and PYY.
This research suggests that how your body processes dietary fat in the intestine—specifically through the enzyme ACSL5—can influence your hunger hormones (GLP-1 and PYY). When this process is altered, it can lead to increased feelings of fullness and reduced food intake, potentially protecting against weight gain on high-fat diets. While this is a genetic mechanism in mice, it highlights the importance of gut hormones in regulating appetite and energy balance.
These data indicate that intestinal ACSL5 serves as a critical regulator of energy balance, protecting mice from diet-induced obesity exclusively by increasing satiety and reducing food intake during HFD feeding. The reduction in food intake observed in ACSL5IKO mice is driven, in part, by increased postprandial GLP-1 and PYY secretion.
Why this rating
High-quality animal study with specific genetic knockout models and mechanistic validation via receptor antagonism.

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
