Multiple causes and effect
Topic: obesity
Thesis statement:
The causes for obesity are unhealthy food habit, the pressure outcomes and lack of exercises.
Facts:. Recent data indicate that roughly 32% of the U.S. population is obese and an additional 34% is overweight.
Topic sentence 1:
Particular unhealthy food habit such as diet contains misbalanced nutrition, animal oil, saturated sugar and excess carbohydrates prime responsible for obesity.
Supporting details:
1. All age and gender groups display hyper-protein nutrition with pronounced cellulose (fiber) deficit, high daily intake of sodium, and misbalance of mineral salts as well as a relative deficit of vitamin A, B1, and PP. The frequency of overweight individuals is 43.9%, while that of obese individuals is 23.1%.
2. extra-intake of fat (over 30 E %), which is observed for 87.9% of all investigate volunteers, and over 40 E% for almost half of the women examined.
3. the research of Dr. Weston A. Price consistently found that when cultures replaced their native diet with white flour, white sugar, and canned food, their health deteriorated and lead to obesity.
4. Obesity is a disorder of fat accumulation as opposed to a disease of overeating (too many calories).
Topic sentence 2:
Large intestine digestive disorder and leptin yield decrease as the response to the pressure from the stressful situations of daily living also lead to obesity.
Supporting details:
5. Our food digestion system (mouth, esophagus, stomach, small intestine, large intestine) helps us to obtain energy and nutrients from food. Carbohydrate, fats and protein are each digested differently within the gastrointestinal tract, but surplus calories from these three nutrients are ALL converted to body fat.
6. The importance of leptin in energy balance is illustrated by the extreme obese phenotype induced by leptin deficiency, and by the dramatic reduction in food intake and body weight. While leptin levels are closely matched to body adiposity at steady state, negative energy balance produces a fall in leptin levels that is more rapid than the change in body adiposity.
Topic sentence 3:
Obesity is the outcome of the modern life style as there are plentiful entertainments options which make people rarely do exercise.
Supporting details:
7. When I came to US and start to study in UIUC, the average exercise hours per week decreases to less than 2 hours which is 10% of that when I was in China. And in this situation, I gained the “freshman 15 pounds” within 4 weeks.
8. People prefer to spend more time in front of TV, computer and video game, cause them have less time to do exercise. The intake calories excess the fat-burn which lead to obesity after a lone time.

I like your C&E more, and I want you to work on this topic, Donna. For supporting details for the 1st body, you don't have to mention all three things. Instead, just elaborate on the two most important things. Also, for the 2nd body, I cannot see clearly what you want to claim. Please explain the relationship between obesity and pressure(?) in your paper. If you have any difficulties, just let me know. I'm looking forward to reading your paper soon!
