Fast food can be a bad habit if you eat it a lot and if you choose the wrong food. Children love it because they get a toy in their happy meal. Adults love it because it is a quick way to do breakfast, lunch and dinner. Depending on the portion size you get depends on how many calories you intake. Here is a list of top places to get fast food and the food that is the healthier option on their menu.
One fast food restaurant that will probably shock you is KFC. 'You don't have to revert to a side salad to eat well there. To lower the fat in my order, though, it's crucial to strip any skin off the drumsticks—they taste great, even without it. As for the mashed potatoes [90 calories and 320 mg of sodium], I dip the fork in the gravy rather than dumping it on. It saves almost 30 calories and I still get a hit of flavor." http://www.health.com/health/gallery/0,,20630037_4,00.html
Anther healthy option menu is Burger King. Your probably saying to yourself how can a greasy hamburger be healthy. The burger alone is around 300 calories . If you take off a lot of added toppings you have saved yourself a ton of calories.
