Wendy's wins it!!!

You could eat 10 nuggets from Wendy's and still eat fewer calories and fat grams than five super-sized chicken strips from McDonald's. Wendy's 10-piece (without sauce) contains a reasonable 440 calories, but is fairly high in fat (29 grams), due to the crispy, fried outside. McDonald's chicken strips are larger. When you eat just five, you're taking in 630 calories, 51% of your daily value of fat (33 grams), and 65% of your daily allotment of sodium.

You could eat 10 McNuggets for still fewer calories than the Chicken Selects (420 calories and 24 grams of fat). Whichever you choose, limit calories by using less dipping sauce. At McDonald's, most sauces (besides the 200-calorie-per-pack Creamy Ranch) contain between 50 and 70 calories each. All of Wendy's sauces vary between 28 and 35 calories per pack.

My favorite burger lost....the answer!

Oh my, the burger I eat on the road ALL the time! wow...
The Big Mac is, well, big--but it still has fewer calories than a Whopper. The Big Mac weighs in at 560 calories and 30 grams of fat (with 10 grams of artery-clogging saturated fat). Obviously, it's not a "diet" food. The Whopper, however, is even worse: 670 calories, 39 grams of fat, and 11 grams of saturated fat. Want to make either one healthier? Skip the cheese and special Big Mac sauce, and you'll take in only 420 calories and 17 grams of fat. When it comes to the Whopper, simply losing the mayo will save you 160 calories and 17 grams of fat (bringing it down to a healthier 510 calories and 22 grams of fat). Who says fast food has to be fat food?
