Why FitPros find the Energy balance hard to understand
The Energy Balance equation is often seen a s a tricky module within Level 3 Nutrition exam syllabus, so you are not alone if you find this area difficult to understand.
Most fitpros understand the concept of weight maintenance, weight loss, and weight gain through manipulating Energy input and Energy output
However, confusion often occurs when learners believe that the only energy expenditure we have is exercise
7 mins Video Tutorial: The Energy Balance Equation
What’s the difference between Energy Input and Energy output
The term Energy Input makes reference to anything we consume that has calories associated to it:
- Food from all three Macronutrients
- Drink that has a caloric value (incl alcoholic drinks)
The term Energy output makes reference to anything that we do that requires energy. This is not just exercise but also our metabolic rate and thermic effect of food.
- Basal Metabolic Rate (aka BMR): This is the energy required to keep all vital organs and processes working whilst at rest. This makes up most of the Energy Output Volume
- Thermic Effect of Food: This is the energy required to break down and absorb the foods we eat.
- Activity Levels: This includes structured exercise, also called EAT (exercise activity thermogenesis). It also includes NEAT (non-exercise activity thermogenesis) which is all unstructured exercise, like walking around the house, fidgeting etc.
Understanding Weight management with the energy balance equation
The Energy Balance Equation simply states that if the energy Input is 2,000 kcal per day, and the combined energy Output is also 2,000 kcals then there will be weight maintenance.
Weight loss occurs if the energy Output exceeds the energy input
Weight gain occurs if the energy input exceeds the energy output
- The energy balance equation shows the relationship between energy input and energy output.
- Energy output is not just structured activity, it also includes NEAT, BMR and Thermic effect of food
- Knowing the energy balance equation will be key as you can expect 4 to 6 exam questions in your L3 Nutrition exam
