Causes of obesity?

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

1. excessive intake of empty calories (nutrition accounts for 80% of the way a body looks)
2. lack of physical activity
3. stress (releases hormone cortisol which induces higher rate of fat storage)
4. genetics (this plays a much lesser role in body appearance than people would like to think. often times people feel better about themselves if they can blame this rather than the fact that they're not doing some right in terms of nutrition and fitness.)

well first i would put lack of exercise as most kids nowadays instead of sending time with friends outside " talk" to them online...number 4 and 1 go together all too well as most people tend to overeat when stressed, also that theyare inside lacking exercise, the fridge is close..and genetics...well...that can be beat, but no one bothers as it is too much work....overall these 4 go together like PB and J...but my rank would be
