Is fast food really bad for you? Well, the obesity level in 2050 will increase to 42 percent. Children who eat fast food for their regular meal time will consume more fat. Junk food in these children's diets account for 187 extra calories per day, leading to 6 additional pounds for weight gain per year. Obesity increases your risk for cardiovascular disease, diabetes, and many more health conditions. Your insulin levels become elevated when you eat processed sugars, such as soft drinks, white flour and other foods that devoid of fiber and nutrients necessary to properly metabolize carbohydrates. Eating junk food every day makes your insulin levels go even higher, which eventually your cells begin to ignore this important hormone, resulting in a condition such as insulin resistance.You also miss vitamins that you need to process in your body. Some nutrient deficiencies lead to low energy, mood swings, sleep disturbance and  poor academic achievements, among other health conditions. Even some of McDonald's foods aren't even real meat. It's a processed ammonia hydroxide called "pink slime". McDonald's has confirmed to never use "pink slime" in their beef ever again. But nobody really knows if they're still using it or not. That to me makes me never want to eat McDonald's ever again. I mean their ketchup even causes obesity. The following ingredients in ketchup are: liquid sugar, white vinegar, salt, onion powder, and spices. What causes obesity in those following ingredients is liquid sugar. Liquid sugar is actually a fructose corn syrup which always genetically modified corn is a form of obesity. Fast food is never always bad, in my opinion, but it's never always good for you either. Always watch what you eat because you know the saying, "you are what you eat!"
