According to Yale University Prevention Research, how long after weight loss do parts of the body still want you to get fat?
12 months
A BMI that is considered healthy is in the range of
18.5-24.9.
According to the body composition reference standards for adults, a fat level above ________ percent for men and ________ percent for women classifies them as "overfat"?
25;30

The basal metabolic rate (BMR) is the minimum amount of energy needed to maintain basic physiologic functions and keep the body alive. However, this rate is different for each person. Consider the following statements regarding the factors that affect the basal metabolic rate.
A person's lean body mass accounts for around 70% of his or her BMR Stress will affect your BMR.
Which of the following statements is true about positive energy balance?
Intake is greater than energy expenditure.
The physical activity factor for a woman who is considered very active is 1.27.
false
When you maintain an energy imbalance over a long period of time, it will have an effect on your body weight. Consider the following statements and indicate which correctly reflect the result of prolonged energy imbalance on the body.
Cutting even 50 kcal from your daily diet will result in weight loss if strictly adhered to over an extended period of time. When you continually eat fewer kilocalories than you use, your body will use its stored energy to compensate.
A person's estimated energy requirement can be a useful tool for estimating an individual's kilocalorie needs for energy balance. Mia is a 20-year-old active female. She is 5 ft, 3 in tall and weighs 125 lb. What is Mia's EER? Choose the equation below that correctly describes how to calculate Mia's EER. Final answers have been rounded to the nearest whole number
EER = [354 − (6.91 × 20)] + 1.27 × [(9.36 × 56.82) + (726 × 1.60)] = 2366
According to the Yale University Prevention Research Center, why is it so hard to maintain weight loss?
Fat cells do not like being starved and signal the brain that you are hungry.
Which agency reports data on the trends in adult obesity in the United States?
The CDC tracks and reports trends in obesity with the Behavioral Risk and Factor Surveillance System (BRFSS).
Which is the correct equation to use when calculating body mass index?
Weight (kg)/Height (m)2
Overweight men tend to have a higher risk of heart disease than women because they tend to have __________, in which extra fat is stored in the abdomen.
android obesity
The ratio of fat tissue to lean body mass is referred to as

What behaviors were demonstrated in the study as a method to lose weight and maintain it?
diet and physical activity
Which of the following is the most accurate method of determining body composition?
