There are correlation between eating fast food and obesity. Several study has already shown the correlation.

Researchers at the University of Minnesota Medical School, have found that :
  • Families whose meals frequently consist of fast food have unhealthy eating habit and a higher risk for obesity.
  • Food environment of families who ate fast food for dinner more than three times a week consisted chips and soda pop and less fruits and vegetables than families who ate fast food less than three times a week.
  • A higher frequency of fast food dinners was also associated with obesity and a higher body mass index (BMI) in adults.
The researchers compared the study participants' consumption of fast foods and restaurant foods during year 7 and year 10 of the study with their BMIs at both time points.

For each additional fast food meal eaten per week during year 7, BMI increased by 0.13 points, while each additional fast food meal per week at year 10 was tied to a 0.24 rise in BMI. This translates to 0.9 pounds and 1.7 pounds, respectively, for a person 5 foot 10 inches tall. People whose fast food intake rose between year 7 and year 10 showed a 0.20 increase in BMI.

Fast Food Makes You One-Third Fatter

Cheeseburger and fries is so damn nyummy!!! But, watch out for the trans-fats! It’s really bad for you!
Another recent study showing the high trans-fat content of fast food is :
  • leading to higher rates of obesity (1-3 fatter than other fats at the same caloric content)
  • Insulin resistance leading to diabetes
A six years study, set of monkeys were fed a meal consisting of 8% partially hydrogenated soybean oil (trans-fats), which is the same as a human eating a cheeseburger with fries, every single day. The monkey had a distinct belly on them that measured a full 7% increase in body weight compared with a mere 2% weight gain in the other group. In fact, the monkeys had 30% more fat around their stomach, which means they stored more fat despite the fact they ate the same number of fat calories as the other group. The monkeys also developed insulin resistance, a precursor to the onset of Type 2 diabetes.

While the trans-fats can stimulate the pancreas to create more insulin for the body, this makes the body more resistant to control the extra amount of this hormone, which can wreak havoc on blood sugar levels. Some have even surmised that trans-fats change the actual composition of cell membranes so they don't react to insulin as they normally would.

This study is another black eye for trans-fats, which have already been linked to increases in heart disease and cholesterol. However, despite the common belief that all fats are bad (except saturated fat can be good for you), that erroneous assumption has now been put to rest. Trans-fat consumption can lead to higher instances of weight gain and the onset of diabetes.

Most fast food restaurants offer food that is very low in fiber content. It is wise to supplement your diet with extra fiber.
