1. Obese individuals have more (neurons/osteocytes/myofibrils/adipocytes)  than normal weight individuals.

2. After growth ceases, the number of fat cells may continue to increase if energy balance is (positive/reverse/negative/consistent)

3. Obese individuals generally have more (protein/pyruvate/lipoprotein hydrase/lipoprotein lipase) activity in their fat cells than normal weight individuals. This is an enzyme responsible for removing triglycerides from the blood stream and placing them in fat storage.

4. One theory as to why some individuals are more prone to weight gain, and thus obesity, than others, is the (set point/genetic/fixed/inherit) theory which states that a person’s body has its own inherent controls that tend to keep the body within a fixed weight range.

5. Genetic factors determine how susceptible a person is to developing obesity, but (genomic/endogenous/epigenetic/modulation) factors such as a consistently healthy lifestyle and healthy diet can play a significant role as well.

6. The hormone (testosterone/ghrelin/cortisol/leptin) regulates appetite in response to body fat.

7. As a means of controlling appetite and cueing satiety, the (norepinephrine/ghrelin/norleptin/estogren) hormone is regulated by intake.

Bolded words are the options to choose for each question.

1Option d.Adipocytes-tissues Specialzed to Store energy as fat.Since Obese person---More Fat-More Adipocytes

2.Option a Positive-

Energy Balance- relation between intake of food and output of work

Energy Balance positive ------ body stores extra food as fats

Energy Balance negative ------ body use stored fat to make energy for work.

3.Option d-Lipoprotein lipase

Lipoprotein Lipase is concerned with fat storage.

Lipoprotein lipase catalyses the partial hydrolysis of triglycerides and fatty acids--- fatty acids are taken up by the tissue ---re-esterified and stored in adipose tissue.

4.Option a -Set point Theory

Set point-weight range in which body is programmed to function better.

According to Set point theory - one’s body will fight to maintain that weight range. Your body is biologically &genetically determined to weigh within that weight range.

5.Option D-Modulation

Diseases linked to genetic & epigenetic modifications can be influenced by modulation factors like environmental and dietary factors.

6.Option D-Leptin

Leptin is produced by fat cells-that suppresses appetite

7.Option B-Ghrelin

Ghrelin is called hunger hormone as it stimulates appetite, increases food intake and promotes fat storage.

Billie wishes to test the hypothesis that overweight individuals tend to eat faster than normal weight individuals. To test this hypothesis, she has two assistance sit in a McDonalds restaurant and identify individuals who order the Big Mac Special (Big Mac, fries, and Coke) for lunch. The Big Mackers, as they are affectionately called by the assistants, are classified as overweight, normal weight or neither overweight nor normal weight. The assistants identify 10 overweight and 20 normal weight Big Mackers....

2. Calls for primary care providers (PCP’s) to offer obese patients behavioral weight-loss counseling have not been accompanied by adequate guidance on how such care could be delivered. A randomized trial was conducted to compare weight loss during a 2-year period in response to two lifestyle interventions, both delivered by PCP’s in collaboration with auxiliary health professionals (lifestyle coaches) in their practices. The investigators randomly assigned 259 obese adults to one of two types of intervention: usual care or enhanced...

Medical researchers have noted that adolescent females are much more likely to deliver low-birth-weight babies than are adult females. Because low-birth-weight babies have a higher mortality rate, a number of studies have examined the relationship between birth weight and mother's age. One such study is described in the article "Body Size and Intelligence in 6-Year-Olds: Are Offspring of Teenage Mothers at Risk?"† The following data on maternal age (in years) and birth weight of baby (in grams) are consistent with...
