Fast Food and ObesityIf you eat out two times per week, or more, you are 50% more likely to be obese. According to obesity doctor David S. Ludwig, there is a strong correlation between eating fast food and being obese.
Fast Food Causes of Obesity
Fast food has a lot of calories. The average person will eat almost 200 more calories per day when eating fast food. Over the span of a year, the individual may gain over six pounds from eating out a couple times a week.
People eat more calories because they often have sugary drinks with their meals, chips, and often more sugary or higher fat foods.
Economically, you can buy a lot more food by simply supersizing your meal. For a mere 15% of the cost of the meal, you can double the calories eaten. Those looking for good deals will also get larger waistlines.
The sugar content and the type of carbohydrates in the foods make up the glycemic index. Fast food meals most often have increased sugar calories and badly refined carbohydrates. The end result of fast food meals is skyrocketing insulin.
Effects of High Glycemic Loads
According to doctor Ludwig, a high glycemic load will lead to a blood sugar crash a few hours later. Here is the interesting fact.
The glycemic crash is basically the same thing as having low blood sugar. The body will then induce hunger to get the person to eat and restore the blood sugar levels. In effect, the person will have an increased hunger a few hours after eating high glycemic load foods.
It is much better to eat low glycemic foods because the sugar is released slowly and the blood sugar stays stable. This helps to control hunger because the body doesn't have to induce hunger pains to stay stable.
Fast Food History
Fast food really got started in the 1960s. In the period between 1950-1960, around 33% of Americans were obese. Today that number is a lot higher. Today, around 67% of Americans are obese.
The trend line of fast food and junk food success certainly coexists with the obesity trend. We are eating about 20% more calories than we used to and the calories consumed continue to go higher despite all the dietary foods.
Fast food is now on every corner imaginable. The fast pace of every day life sure does make fast food a convenient choice.
Chemicals and Additives
To make money in the fast food industry, the food has to taste good. The food should also last a long time and still taste fresh. The only way to do this is to add chemicals.
The food is scientifically engineered to be addictive. It is also engineered to be produced the least costly way. The end result of market competition is that we eat a lot of things that taste great, but have little nutritional value.
Many of the chemicals are also considered, by scientists, to be cancer causing agents. For example, french fries come with the sweetener dextrose and the antioxidant butylated hydroxyanisole, which the World Health Organisation, has linked with cancer.
