Answer:
"My nutritionist measures energy content of food by using a bomb calorimeter."
Explanation
Animals humans included eat food in order to get chemical energy through cellular respiration either aerobically or anaerobically.
Therefore, food energy is the amount of chemical energy that can be derived from food.
Food energy can be measured using a bomb calorimeter and the unit of measurement is calories.
So when the client made the statement and mentioned energy content in food being measured by a calorimeter, it shows the client had an understanding on how energy in food is measured.
