Metabolic syndrome is caused by modern lifestyle choices like poor diet, lack of exercise, and stress. It increases the risk of diseases like diabetes, heart disease, and some cancers. The metabolic syndrome diet focuses on reducing belly fat through healthy eating, exercise, and stress management. Key aspects of the diet include eating more fiber-rich whole foods, limiting red meat and dairy, and choosing unsaturated fats over saturated and trans fats. Regular exercise and stress management are also important for reducing visceral fat and metabolic syndrome risk.
