What does mcdonalds do to your body?

No, You should only have mc donalds as a treat. Not as a regular meal.. it has a LOT of calories which can make you obese... The link I have enclosed has the nutrition facts... On the fourth paragraph click the nutrition claclulator and drag your meal on the tray, You'd be surprized of how many calories you are eating http://www.mcdonalds.ca/en/food/nutritionpackaging.aspx
