You are still young, if you continue to eat all this fast food the effects will catch up with you as your metabolism slows down. I'll just get my text book to tell you how much crap is in those burgers. It has all the content of every fast food item from various places. Quarter pounder with cheese has 530 calories, 95 Mg of cholesterol, and darn it doesn't have saturated fat listed, but total fat is 30g. Medium fries has 450 calories, 0 cholesterol and total fat is 22g. Daily recommended intake of these are for calories, an average of 2000. This means one mcdonalds meal is half your intake of this. Total fat intake should be 65g. You have already racked up 52 from this meal. The recommended daily intake of saturated fat (saturated fat is bad for your body, will explain why if you want to know) is only 22g, and I'm pretty sure that the meal already covers that. Recommended daily intake of cholesterol is 300mg, and a third is taken up by the hamburger alone. The healthiest thing I can see on the McDonalds Website is probably croutons. (figures taken from McArdle, Katch & Katch, 2001) Yes I am a health freak. You health nuts are going to feal stupid one day, lying in the hospital dieing of nothing.
