Fat is stored energy. It’s not evil and it’s not wrong – it is there by design and you will always have some unless you are no longer interested in living. We consume food to live, some of it is used up right away so we can continue thinking and breathing and some of it, whatever is left over, gets stored in the fat cells for later.
Once we hit adulthood the number of fat cells in our bodies remains the same – think of it as “pockets”. We can fill them up or empty them, but we can’t get rid of the pockets themselves – the cells always stay there, they just get bigger or smaller.
Fat is essentially the fuel we use to keep on going when we most need it. Think of the human body as an organic machine that runs on energy, it runs on the food we consume and once there is a shortage, it dives into the reserves in the micro vaults – the fat cells. As you burn it and use it up turning it into energy there is nothing left but the byproduct – carbon dioxide. Yes, you breathe it out.
To force and speed up the process and make our bodies dig into the reserves we have two options: diet and exercise, that’s where “eat less and exercise more” comes from.
