Did you know that your body burns fat or carbs depending on the intensity of your activity? You burn fat even if your body is at rest. Actually, you are even burning fat right now sitting in the front of your computer. Your body is burning about one or two calories per minute (about 70 % comes from fat and about 30% comes from carbs).
When you exercise, as the intensity increases, your body starts using more and more carbohydrates for energy instead of fat. With high intensity aerobic exercise, 100 percent of the energy is coming from carbs. But here is where it gets interesting…when carbs are no longer available, your body will break down muscle and use it for energy. When carbohydrate stores are depleted, the rate at which fat is used as energy is reduced, and that’s why carbs are essential in order to metabolize fat.
The best way to lose fat is when you burn more calories than you eat on a daily basis, not because you burn fat when you are exercising.
When you eat after your workout, you rapidly replenish both the carbs and fats that you have used up during the workout. But as soon as an excess of calories (from either fats or carbohydrates) exists, your body will begin to store them as fat. So don’t go pig out after your workout or your body’s fat stores will be virtually unchanged.
This is why diet + exercise really do work the best, but your exercise regime must include cardio and WEIGHT TRAINING. When in doubt, do resistance training.
The key to fat loss is to manage your calories, so your body doesn’t store them as fat, and to boost your metabolism so that your body is continuously burning calories at a higher rate 24/7. People with muscle mass are automatically burning more calories (and fat). Every 1 pound of muscle that you build on your body will burn up to 3,000 extra calories a month which equals roughly .5 pounds of fat. I know that .5 pounds doesn’t sound like much, but that .5 pounds is burned by doing nothing but sitting around. It is a way to give you an added advantage as you continue on your weight loss path. Bonus – more muscle makes you look healthier and slimmer!
So, the perfect combo is healthy diet, resistance training, and cardio.
