I am doing the research paper on obesity in America and the several factors that contribute to obesity such as; temptation or proximity to fast-food restaurants, low-income, shortage of time lack of education and perhaps even genetics depending on the amount of information i have. Another question can my research paper be cause and effect because I could use some effects of obesity such as low self-esteem, health problems and so on. if yes what else could i use?
Thank you

I am sure everyone here knows of the health risks of obesity: heart disease, joint problems, etc.

Just looking for some explanations:
-If obesity is genetic, why are so many more Americans obese today than the previous generation? Shouldn’t the rates be the same if obesity is genetic?

-In this case do you think that obesity would better be controlled by lifestyle changes or by gene therapy? (or surgery)?

-Do you think that obese people will use "genetics" as an excuse to stay at an unhealthy weight because they can’t help it?

In your opinion, how would you rank the importance of these 4 factors in causing obesity?

1. Excessive intake of empty calories.

2. Lack of physical activity.

3. Genetics

4. Stress
