BALANCE AND METABOLISM REVIEW
QUESTIONS ANSWERS STRUCTURED
GUIDE
◉ Obesity is defined as a BMI, or body mass index, greater or equal
to 30.
Answer:
◉ energy excess
Answer: Consuming more energy than is expended. Also called
positive energy balance.
◉ energy deficit
Answer: Expending more energy than is consumed. Also called
negative energy balance.
◉ Your BMR is the minimum amount of energy you need to function
Basal metabolism is the amount of energy expended to meet the
basic physiological needs that enable your organs and cells to
,function. Also referred to as your basal metabolic rate (BMR), it is
the minimum energy needed to keep you alive.
Answer:
◉ Energy balance is the relationship between your energy intake
and your energy expenditure, which are both measured in calories.
Your basal metabolism, the thermic effect of food (TEF), and your
physical activities all determine your daily energy needs. When you
don't eat enough calories to meet your needs, your glycogen and fat
stores, as well as muscle mass, will be broken down for fuel. A
chronic deficit of calories will produce weight loss. When you
chronically consume more calories than you need, the excess will be
stored as fat, and weight gain will occur.
Answer:
◉ Which of the following decreases basal metabolic rate in an
individual?
Fasting for more than 48 hours
Having a larger body size
Increasing lean muscle mass
An increase in thyroid hormone
Answer: (answer: a)
, ◉ Thermic Effect of Food (TEF)
Answer: energy used to digest foods and beverages as well as absorb
and further process the macronutrients
◉ lean body mass
Answer: total body mass minus its fat
◉ 1) Which of the following is considered a "medium" in the scale of
energy dense foods?
Crackers
Cottage cheese
Lean sirloin steak
Fat-free yogurt
Answer: steak
◉ Summarize healthy strategies for achieving and maintaining
healthy body weight.
