In insulin-resistant subjects, a monounsaturated fatty acid (MUFA)-rich diet significantly improves postprandial glucose and insulin responses compared to a carbohydrate-rich diet, while increasing GLP-1 secretion.
If you are insulin-resistant, choosing a diet rich in monounsaturated fats (like olive oil) over a high-carbohydrate diet can significantly improve your blood sugar and insulin response after meals. This benefit occurs even if you maintain your current weight, suggesting that the quality of fat is more important than the quantity for metabolic health in this population.
The MUFA-rich diet improved insulin sensitivity... After a MUFA-rich and high-SAT breakfasts (443 kcal) the postprandial integrated area under curve (AUC) of glucose and insulin were lowered compared with isocaloric CHO-rich breakfast... while the integrated glucagon-like peptide-1 response increased with MUFA and SAT breakfasts compared with isocaloric CHO-rich meals
Why this rating
Small sample size (n=11) and short duration (28 days), though crossover design controls for individual variability.

- 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
