Maintaining a healthy weight can be challenging, especially as you age. Fat is created by the body when diet produces more calories than you need to function at your current level of physical activity. To lose fat you have to increase your physical activity and decrease your calorie intake, which will draw the extra energy needed from your stored body fat. If you are looking to burn 15 lbs. of fat you will need to be diligent to get the results you desire.
Do cardiovascular workouts to burn fat. Running, swimming and bicycling are good examples of cardio workouts. Do cardio three to five days a week for 30 to 60 minutes to lose 1 to 2 lbs. a week. You could reach your 15 lb. fat loss in less than eight weeks with a successful cardio regimen.
Eat several small meals throughout the day. This will help you stay full and keep blood sugar levels stable.
Add fruits and vegetables to your diet. Fruits and veggies are low in sugar and fat. Eat lean meats such as pork and chicken -- and avoid foods high in calories and fat like desserts.
Drink lots of water. Water helps boost metabolism, which burns more calories and eliminates fat.
Be consistent with your diet and exercise routine. Keep in mind that it takes time for weight loss to become visible.
