The thing about humans, in general, is that we don't refrain from doing anything that may harm our health. In fact, we find more ways of doing the wrong thing and finding a solution to keep ourselves healthy at the same time. One can simply not smoke, right? But no! We came up with e-cigarettes. It is the same with food & drinks. You can probably only eat one burger at McDonald's but if you have three and a shake to go with it, your body will need repairing. So what do we do? Exercise!
Since we will never change this habit of eating junk food and consuming harmful beverages all our lives, why not run it off & burn some calories? We'll lend you a helping hand by telling you how much you have to run when you consume certain food items, but after that you are on your own.
