Men who have extra weight, especially around the waist, have a higher risk of type 2 diabetes, high blood pressure, heart disease and stroke. But they have nature on their side if they want to lose weight. Genetically, men tend to have less fat than women, more testosterone and muscle tissue. This distribution makes it easier for them to lose weight, as long as they do well. Weight loss should occur at a gradual pace. Fad diets that drastically reduce calorie intake should be avoided because they can cause weight gain, metabolic disorders, yo-yo diets and nutritional deficiencies.
