At my age burning fat from the belly is a very difficult task. Burning fat from the belly is easier for adults who are between the ages of 20 and 45. Once you get past this it takes much longer to burn belly fat. Exercises are the best option and I have been doing cardio for the past few years on a regular basis. Cardio exercises such as walking and light jogging are the best option for those who are middle aged. This will not only help you burn fat, but it also helps you stay fit and focused. Good Luck!
