Q

Moderate weight loss in an obese person can reduce the risk for heart disease or diabetes

24
Q

being underweight can increase the rist for certain health problems

25
Two types of storage fat
Visceral fat, subcutaneous fat
26
Healthy percentages of body fat in young men and woman(20-39)
men 8-19%, women (21-32%)
27
Recommended percentages of body fat in young men and women (20-39)
men 12-15%, 21-25% women
28
Athletes may have body fat percentages in these ranges
men 5-13%, woemn 12-22%
29
T/F: Where you carry body fat matters just as much as body fat percentage
T
30
Which fat storage area of the body leads to a greater risk of heart disease
waist area
31
Percentages of over weight adults and children in the U.S.
adults 34%, children 17%
32
Obesity directly contributes to this percentage of deaths in the U.S.
15-20%
33
Percentage of health care costs associated with obesity, and dollar amount
10%, $147 billion dollars per year
34
Percentage of Americans that are obese or overweight
67%
35
How much weight does the average college student gain in their first year of college
4-15 lbs
36
Obesity increases the risk of developing at least this many diseasese
26
37
Obesity increases the risk of heart attack by this percent
60-80%
38
Number of people effected by diabetes
18 million
39
What percentage of people with type 2 diabetes are obese,
80%
40
When does the ricks increase for getting type 2 diabetes
after age 45
41
decreased insulin sensitivity
common with type 2 diabetes, tied to the bodies reduced ability to transport glucose from the blood to the cells
42
What percentage of weight loss can reduce the risk of heart disease and type 2 diabetes
5-10%
43
T/F: Tables are the best way to predict if someone is overweight
F
44
Healthy BMI for men and women
< 25 kg/m^2 is healthy, > 30 kg/m^2 is unhealthy
45
Is BMI the best way to predict obesity
No, a heavily muscled adult may have a high BMI, but actually have low body fat
46
Key factory that may affect the relationship between BMI and body fat percentage
muscularity
47
This percentage of body fat is subcutaneous
> 50%
48
Most common method of assessing body fat in fitness centers
bioelectrical impedance analysis
49
Advantages of bioelectrical impedance analysis
widely available, low cost, and limited time requirement
50
disadvantages of bioelectrical impedance analysis
may not be accurate for your sex, age, and over all level of fatness
51
Three common assesments of body compossition
BMI, skinfold test, waist to hip ratio
52
Factors that should be used in determining the optimal healthy body weight
level of body fat for your age, height, and sex
53
T/F: Ideal weight can be easily calculated if you know your percentage of body fat
T
54
T/F: You shouldn't get regular body composition assessments when trying to gain or lose weight
F
55
T/F: Assessments should be made with the same procedure as the original assessment
