How our food culture has changed over the years and why obesity has become very common

I have read an article about how our meals have grown larger in order to fulfill our appetite. This is beginning to become a problem because as the years have gone by the meal size has grown 4% and that's in the year 2010. We are in the year 2018 now, imagine in 2018 how much it has grown from then. An example would be in the year 1950 the average calories consumed by a person was about 2,109 calories. In the year 2010 it was averaged to be about 2,500 calories. In order for us to cut down on obesity we must be able to, as a society to become strong mentally. As one we should to begin to cut down on foods we eat. It all starts first at the fast food restaurants because they're the ones that increased the sizes in our meals. Here are some major increments  that have been brought to you by them. If you went to a fast food hamburger restaurant back in the 1950s, a regular meal looked like this. A hamburger was 3.9 oz, fries were 2.4 oz and a drink was 7 oz. Not bad right? Well as of now in 2018 a meal like that wouldn't even get us full. An average meal now for a whole burger meal is  12 oz burger, 6.7 oz  fries and 42 oz drink. Right now the U.S is at the number spot in  obesity which horrific. This all needs to stop now and that starts with us. We are the future kids of the U.S so lets make something happen.
