A 22-year old man who consumes 1900 kcal/day and is losing weight. C. A 23-year-old man who lifts weights every other day and has a BMI of 24. D. A 5-year-old girl who is healthy and physically active.

Answer 1

The correct answer is B. A 22-year old man who consumes 1900 kcal/day and is losing weight.

Explanation;

In health, negative energy balance occurs if the number of calories consumed is lower than the energy spent. This leads to weight loss as the body will need to use the fat or even content muscle in the body to supply the missing calories. This is shown in "22-year old man who consumes 1900 kcal/day and is losing weight" because the loss of weight indicates the 1900 kcal/day the man consumes are not enough to supply all the energy and metabolism.
