#5. Avoid sugary and oily foods
When looking for the best way to reduce belly fat without exercise and diet, your first priority should be to avoid sugary, oily, and processed foods. Of course, they are tasty, which is why you grab lots of calories around your belly area. These foods are filled with lots of empty calories that spike your blood sugar levels and cause your insulin levels to spike too. You eat more and more and contain only empty calories.
