Question 1

What caloric deficit is generally recommended to produce approximately 1 pound (0.45 kg) of fat loss per week?

Accepted Answer

3,500 kcal/week

Answer

One pound of body fat contains approximately 3,500 kcal, so a deficit of 500 kcal/day (3,500 kcal/week) theoretically produces 1 lb of fat loss per week.

Question 2

Which of the following is a limitation of Body Mass Index (BMI) as a measure of health risk?

Accepted Answer

It does not differentiate between fat mass and lean mass

Answer

BMI uses only height and weight, so it cannot distinguish between body fat and muscle mass, potentially misclassifying muscular individuals as overweight.

Question 3

What is the minimum daily caloric intake generally recommended for women to avoid nutrient deficiencies during a weight-loss program?

Accepted Answer

1,200 kcal

Answer

Most guidelines recommend women consume no fewer than 1,200 kcal/day to obtain adequate micronutrients; lower intakes risk deficiencies and metabolic adaptation.

Question 4

Which hormone, produced by adipose tissue, signals satiety to the hypothalamus and helps regulate long-term energy balance?

Accepted Answer

Leptin

Answer

Leptin is released by fat cells and acts on the hypothalamus to suppress appetite and increase energy expenditure, regulating long-term energy balance.

Question 5

Accepted Answer

Elevated fasting blood glucose

Answer

The five criteria for metabolic syndrome include elevated fasting blood glucose (≥100 mg/dL), abdominal obesity, high triglycerides, low HDL, and high blood pressure.
