I remember once many years ago watching a great video that properly illustrated the problem. In the video was two guys. One was on a treadmill, and the other had a slice of pizza.
Just one large one, this wasn’t man vs food or anything, but that slice of pizza was about 500-600 calories. Pretty standard.
The task at hand was pretty straight forward. The guy on the treadmill was going to run for the same amount of time the other guy ate his pizza slice.
So one was burning calories, the other ingesting them.
So off they went. One guy started chowing down on the pizza – Not fast, but not slow either, and the other guy went for it on the treadmill.
This was proper hell for leather too! He was sprinting, and if it was a cartoon, smoke would have been coming out of the treadmill belt.
It took the one guy about 2 minutes to get through the 500 odd calorie slice of pizza.
On the other hand, by sprinting for 2 minutes, the other guy had burned around 33 calories.
So the point was pretty obvious! You can take in 500 odd calories in about 2 minutes, but to burn that off, that 1 single slice of pizza, you would have to sprint for over 30 minutes. (And yes, it’s impossible to sprint for 30 minutes, but you get the point!)
In short, trying to burn off what you eat through exercise is a false economy.
Unless you’re an extreme endurance athlete, you’re never going to burn enough calories during exercise to make a dent.
However, there is a way to burn more, and that’s using a concept we call Afterburn.…
