Most fast food ingredients contain more energy, total fat, saturated fat, carbohydrates and added sugars than healthier food of the same weight.
2. Larger Portion Sizes Make Fast Food Cause Obesity
As popularized by the 2004 documentary Super Size Me (if you haven't seen it, you can watch it for free here), the problem with the ingredients of fast food is further compounded by fast foods’ growing portion sizes.
3. Low Cost Makes Fast Food Cause Obesity
Researchers at the University of Washington found that a 2,000-calorie diet of junk food costs 10 times less than a 2,000 calorie healthy diet. 6 This low cost of fast food encourages people to choose it over more expensive healthier food, which is a big reason that lower-income individuals are more likely to be obese.
4 Convenience Makes Fast Food Cause Obesity
The final factor that makes fast food cause obesity is its convenience, or more specifically, how close fast food restaurants are to your home, job or school.
