Ovesity with fast food

Obesity is a problem that is increasing very fast in developed countries. The main problem is that a lot of people think fast food isn't really bad but the truth is that fast food is really bad. It contains so many calories, for example a big mac contains 550 calories and that is more than 1/4 parto of calories you can get in a day if you are an adult man. And if you eat fast food you wouldn't eat just the hamburger you would eat some fries and maybe you would have a coke or something to drink too. So it is like 1000 calories for only 1 meal. It is the half of an adult can eat in a day and we should have 5 meals a day so you will eat more than you should and also it's basically a meal based in fries and a lot of fat.
