Exercise to your heart’s delight. That’s great. Just as long as you’re doing that, doesn’t matter how hard or fast, or how soft the intensity of your exercise regime, you’re going to be alright. When you’re starting out, you’re not going to be doing high intensity exercise. After about three or four months, provided that you’ve begun to lose weight and your cardiovascular levels have increased exponentially, you can do high intensity exercises which will boost your fitness levels still higher. But wait a moment, something is missing here. How are you expected to get healthy and fit on just exercise alone? You must still eat, right.
