Reducing belly fat requires a combination of healthy eating, physical activity, and lifestyle changes. Focus on cutting out refined carbs, sugary drinks, and processed foods. Eat more lean proteins, fiber-rich foods, and healthy fats like nuts and avocados. Engage in regular exercise, especially cardio like walking, cycling, or swimming. Strength training also helps build muscle and burn fat. Manage stress and get enough sleep, as both can influence weight gain. Avoid fad diets—sustainable, long-term habits work best for fat loss.
