So it really is true when they say that fitness is a combination of both diet and exercise. This is even more relevant when you want to talk about your metabolism. You see, your body’s metabolic rate is responsible for how fast or how slow your body burns up calories in your body. This also means that it will spell the difference on whether or not you would be gaining a few more pounds or inches for that slice of pizza or cake that you had the other night. If you want to eat as much as you want, then you will need to boost your metabolism. Think of it this way, a large SUV like a Range Rover consumes a significantly larger amount of gasoline than say a smaller car such as a Smart car. If you want your body to consume energy like an SUV, you need to boost your metabolism. This is tantamount to having a car with a larger engine. And for you to be able to do this, you need to exercise more. Do sprints and other exercises that pushes your body to go harder, faster, or stronger. This will allow your body to consume a larger amount of energy to fuel your muscles so you can do your desired task. Think of Michael Phelps. How would it be possible to wolf down plate after plate of pasta, pizza, and whatever type of food he wants without getting fat? It’s because he is a beast in the swimming pool.
