They found that obese individuals sensitive to insulin in muscle or liver are metabolically healthier, with lower blood pressure and less deep abdominal fat. This discovery provides significant insight into human ins...
A Cornell University study suggests that diet and physical activity are key factors in managing weight, rather than eliminating specific foods like junk food.

New research suggests that obese patients with type 2 diabetes should be prioritized for obesity surgery, as they often experience remission of diabetes and reduced healthcare costs. The study, based on the Swedish Obese Subjects (SOS) study, found that total healthcare costs were lower in surgery patients who had prediabetes or diabetes.
A new study found that mice lacking certain immune cells gained excess weight and developed metabolic abnormalities even on a standard diet. Removing these cells prevented weight gain and metabolic issues. The study indicates that immune cells may help control fat tissue's energy storage and reduce inflammation.
