Let us take a look at this cause and effect relationship between junk food and obesity. Fast food restaurants offer convenience. tween fast food restaurants and obesity on a state-wide basis. Design. A one-time These results indicate a correlational relationship between both the number.

A total of three studies [ 252650 ] characterized the fast food environment based on both density and proximity measures. Several studies further described the food environment by incorporating measures of food outlets other than fast food restaurants. The most commonly included food outlets were full-service restaurants, convenience stores, grocery stores, supermarkets, outdoor food stalls, and cafes.

High densities of fast food restaurants are not associated with high levels of obesity

Several studies [ 164950525455 ] also examined the built environment beyond solely food, studying factors like street connectivity, number of bicycle paths, and the number of subway stations. Associations found between the fast food environment and obesity: The associations found were varied in nature. Once again, the conclusions presented by the studies that found no significant association were varied in nature; for example, Hickson et al.

Finally, although some of the studies found no significant relationship between fast food availability and BMI, they found significant relationships between the availability of other food outlets and BMI; for example, Koleilat et al. Also, similar to the studies within the US, the associations found were varied in nature.

For example, Fraser and Edwards [ 25 ], found that within the UK, a significant positive association between fast food availability and obesity rates only when using density measures no significant association found while using proximity measures.

Interestingly in the final study performed in rural China [ 21 ], a significant negative relationship was found between the fast food environment and BMI. No such relationship was found elsewhere.

The relationship between obesity and the prevalence of fast food restaurants: state-level analysis.

Similar to the US studies, although some of the studies found no significant relationship between fast food availability and BMI, they found significant relationships between the availability of other food outlets and BMI. For example, Larsen et al. Du et al [ 21 ], a longitudinal study performed in rural China, found no significant association between the fast food environment and BMI for men, and found a significant negative association between the fast food environment and BMI for women not found elsewhere.

Associations found between the fast food environment and SES: All of these studies demonstrated similar findings: Examples of such studies include 24,54, For example, although Laxy et al. Studies performed outside the US Similarly, a majority of included studies conducted outside the US incorporated various measures of SES, primarily as a controlled variable.

Fast Food and Obesity – The Cause and Effect Relationship

The findings were similar to the findings of the studies performed in the US: Higher SES was associated with lower obesity rates and lower concentrations of fast food restaurants.

Similar to US studies, these findings were present across all the studies that included SES, even those that found no direct associations between the fast food environment and obesity; for example, Fraser et al. This review sought to specifically compare the relationship between the fast food environment and obesity in the US and other countries throughout the world. The studies performed in the US and countries outside the US both demonstrated largely mixed results in terms of the relationship between the fast food environment and obesity.

Thus, the fast food environment may be associated with higher rates of obesity in areas with lower SES and higher concentrations of ethnic minorities in both the US and countries other than the US. However, as a whole, similar to a review performed by Fleischhacker et al.

High densities of fast food restaurants are not associated with high levels of obesity

There are several limitations to our approach. Let us take a look at this cause and effect relationship between junk food and obesity.

Obesity and Calorie Intake Increase in calorie intake and inadequate physical activity are the leading factors of obesity.

According to the National Health and Nutrition Examination Survey, the intake of calories in the US population is increasing every passing year. The numbers have risen alarmingly in the past decade. There are four basic reasons why fast food is linked to obesity.

Unhealthy Ingredients Most of the fast food contains a large amount of sugar, fats and carbs and less minerals and vitamins. This means that you are taking in large amount of unhealthy calories in the shape of fast food which leads to weight gain and ultimately obesity. Most of the fast foods have exceeding levels of sugar and fats which are directly associated with increasing weight.

Larger Portions The unhealthy ingredients of the fast food are further aggravated with increased portion sizes which have grown parallel with the average body weight of a person from the 70s to date. While the portions have become large, the person will still eat the complete meal regardless of feeling full or not.

This means that people are eating bigger portions of junk food leading to abnormal weight gain.
