We're going to chew up "the heat index" next. Eye-opening news for fast food fans. 2,000 calories is the recommended daily amount for adults. But some fast food chains are serving close to that in just one dish. Linzie janis has the fast food meal that may put you over your limit. Reporter: Roll into the drive-through and the meal you order may have more horsepower than the family minivan. According to the website, marketwatch, some of the highest calorie meals are on the menu of our favorite fast food restaurants. And they could push you over the daily limit of calories.

The chicken rings alone on our plate, that's 2,000 calories or almost. These are 1,000. They make a point to say this is one serving. They expect three or four people are sharing one serving of said rings. Amy already told me she will not share hers with me. No. I'm not a sharer. This is 800 calories right here.
