Fat Loss Success Series: How Do We Actually Lose Fat?

This time of year can trigger immense pressure to "get fit" or "lose weight", so we want to help you do it right and understand what you're doing! Starting with part 1 (of 5) of our Fat Loss Success Series - how do we actually lose fat?

Simply put, your body requires energy to actually work – just like a car requires fuel. We talk about energy in the form of calories or kilojules – both are the same, calories is the American measurement and kilojules is the Australian measurement. You can convert calories into kilokules by multiplying it by 4.2.

The amount of energy that our body requires day to day changes based on a number of factors. These include:

  • Our BMR

  • NEAT – non-exercise activity thermogenesis

  • Exercise activity

  • The thermic effect of food

BMR is the number of calories you’d expend if you were to do nothing – no eating or moving – just breathing.

NEAT – this is all your little movements and incidental activity that you wouldn’t class as exercise. Its sitting, standing, waving your hand.

Exercise activity – you know what this is, this is your hard work at the gym or general exercise.

Thermic effect of food – to digest and metabolise food it actually takes energy!

When you add up the effect of all of these factors, you find your daily energy expenditure.

So if we actually think about this for a second, how many of you would say that your daily energy expenditure would be consistent every day? Do you eat exactly the same, train exactly the same and are all your incidental movements the same?

For most of us, our daily requirements can vary quite significantly and that is why you may be more hungry on some days than others.

To maintain weight, you need to consume the same amount of calories from food as you are burning.

If you consume more calories, your body will put that energy into storage, and you may gain muscle or fat.

If you are consuming less calories, your body will tap into those energy reserves and you will lose weight.
