When considering insulin and weight loss, the key focus is on insulin sensitivity and resistance. Insulin is an anabolic hormone that promotes fat storage. To lose weight, maintaining stable blood sugar through a low-glycemic diet, regular exercise, and possibly medical interventions like metformin or intermittent fasting is recommended. Direct insulin injections (e.g., for diabetes) can hinder weight loss by blocking lipolysis. Evidence for specific 'insulin diets' or supplements is weak; most claims are based on observational studies or mechanistic reasoning. Be cautious of marketing that portrays insulin as a fat burner. Always consult a doctor or dietitian before making changes related to insulin and weight management.
