Total Energy Expenditure correct answers This is the sum of your Basal Energy expenditure,
your Basal Metabolism when you're not moving, thermic effect of food, how the food is
absorbed and digested, and how much physical activity you expend throughout the day.
This also includes the regulation of your body temperature, deposition of new tissues, and
production of milk.
Your T.E.E is based off 3 components, your Basal Metabolic Rate, or BMR, which takes up 60-
75%, your physical activity which takes up 15-35%, and your Thermic Effect of Food which
takes up 5-10%.
Factors that Affect BMR correct answers These factors are fairly simple; consisting of Height^,
Age, and Overall Growth^.
It also includes your lean tissues^ and the event you have a fever and/or stress ^.
A low calories Diet and Malnutrition decreases your BMR if under <1200cals.
BMR (basal metabolic rate) correct answers Your BMR is the rate at which your body burns
energy when you're at rest or expending minimum energy. This is 60-70% of your total energy
which includes your heartbeat, respiration, and body temperature regulation. Digestion and
"voluntary activities" are not included within this rate.
Characteristics of Successful Diet Plans correct answers Good diet plans are very easy to point
out, consisting of a slow and gradual weight loss, change in behavior (including exercise),
including all food groups and food variety, and aiming to permanently change one's lifestyle.
This permanent change could also include choosing an activity you like that you included into
your daily life. (EX. Basketball)
This plan could also include logging food and physical activity.
Characteristics of Unsuccessful Diet Plans (FAD Diets) correct answers FAD Diets main
characteristic is it's clear lack of being realistic. These diets promote rapid weight loss through
anecdotal or overly promoted testimonials.
These diets are the complete opposite of a successful diet, requiring little to no exercise or
changed behavior. More importantly, they exclude whole food groups, requiring the participant
to intake supplements.
MERIDIA (SIBUTRAMINE) correct answers This is a weight loss drug that acts as an appetite
suppressant. It blocks your serotonin reuptake (preventing it from breaking down) thus
decreasing your appetite.
, With it's side effect including increased blood pressure, this drug was removed from the market
due to the increased risk of heart disease.
PHEN-FEN correct answers This weight loss drug also suppresses appetite through serotonin.
This drug caused heart valve defects and was removed from the market by the FDA.
XENICAL correct answers This weight loss drug inhibits the production of fat-digesting
enzymes. This causes the fat you consume to not become digested, but rather excreted. This will
result in a loss of fat-soluble vitamins.
While taking this drug, you must follow a low fat diet in order to avoid symptoms such as GI
Pain (gastrointestinal) and oily stools.
Gastric Bypass Surgery correct answers This is a type of Bariatric Surgery that limits food intake
by reducing the capacity of the stomach
Gastric Bypass Surgery Risks correct answers Complications follow this surgery including
infections, nutrient deficiency, bleeding, decreased CA2+ absorption (which increases the risk of
osteoporosis), and decreases B12 absorption. This surgery is also very expensive, costing
between $20,000-$40,000.

with 75% of patients losing 50% of their weight. This weight loss is due to the limited amout of
food consumed and malabsorption.
