We know now that the traditional explanation - that of overeating - is wrong. People eat when they're hungry, and they stop when they're full. The problem lies in hormonal imbalance inside our bodies, an imbalance that deprives us of the energy to live life to the full, and instead stores the energy as fat.
So what influences human hormonal balance? And, more to the point, can you control your hormonal balance?
The three biggest factors are:
There are no prizes for guessing which one of those three is the easiest to control. There is nothing you can do about your genetics (except envy those who can eat anything they like because they chose their parents well...) It is very hard to control the stress in our modern lives.

But you keep pouring in thirty litres every week.
As time goes by, your tank swells more and more, until eventually it starts dragging itself behind the car, impairing its movement. You have to do something.
You have four options. You can:
These are basically the three approaches to weight and/or fat loss:
