Nutrients
Food broken down into glucose to use for energy

Measures heat from food
Direct calorimetry-/ bomb calorimeter
Not a reliable indicator of micronutrient and macronutrient adequacy

Calories are based on this system
Atwater
Can affect how calories are absorbed differently

Not as efficient at extracting energy from foods
Bacteroidetes

Indirect calorimetry
Reasons why some may be people successful at counting calories
Look at other health factors
Not counting every day
Ask what is their relationship with food like
