Calorie Equation – Energy Equation
The calorie/energy equation goes like this:
Change in stored energy = energy intake less energy expenditure
Simpler Calorie/Energy Equation
A much simpler equation is:
“if calories-in = calories-out, your weight stays the same!!”
- So if energy (calorie) intake equals energy expenditure (physical activity), there is no change in stored energy (body weight): i.e. you neither gain nor lose weight.
- But if energy intake exceeds energy expenditure, there is an increase in stored energy and you gain weight. (Positive energy balance)
- If energy intake is less than energy expenditure, there will be a decrease in stored energy and you lose weight. (Negative energy balance)
