Does dietary fructose restriction improve cardio-metabolic health in obesity?

This study is testing whether cutting back on fructose (a type of sugar found in many processed foods and drinks) can improve heart health and metabolism in people who are obese. High fructose diets have been linked to obesity, high cholesterol, high blood pressure, and diabetes risk. Participants will follow a low-fructose diet for a set period and researchers will measure blood fats, hunger hormones, and markers of inflammation.
