High intensity training or HIT, often referred to as HIIT which actually stands for High Intensity Interval Training has been presented as some kind of magic bullet for fat loss in recent years. I mean, I was even taught this when I first did my level 3 personal trainer diploma. The main reason we are told that HIIT burns more fat than other forms of exercise is because of something called Excess Post-Exercise Oxygen Consumption or EPOC for short. This is often referred to in more simple terms as ‘the afterburn effect’. The theory being that after a bout of very high intensity exercise you burn more Calories while you recover. Some sourced have claimed that you could burn an extra 1,000kcals over 24-hours. This is completely false. Let me explain more.
It seems like every day the newspapers print some rubbish about fitness or nutrition. The headline is more often than not scary and sensationalist. No surprises there then.

I have also done numerous videos on this topic, one of which you can see lower down this article. So, to help you stop pissing in the wind here is a brief introduction to how Calories work and how to estimate and track your Calories.
