If you eat well the rest of the time, it's not all that detrimental (as far as I know).

Yes, It's all about having the right balance.

Too much of anything Is not good for you. Even too much water (known medically as "water Intoxication") can be detrimental to one's health. I eat extremely healthy and don't have any (zero) McDonald's. My doctor did advise however, that eating takeout once a week does not have any damaging effects on your health.

On topic, when I used to eat McDonald's many years ago, I enjoyed the offers that came with It. Probably the main reason of selecting McDonald's- just for the chance of wining a prize.
