Personal Trainer Michael Cañas took a weight loss challenge to the extreme when he lost a full stone in a day.

But it was not because he felt the need to shed the pounds - it was all in a bid to challenge the many weight loss myths he has heard over the years.

He says one of his main motivations for getting into fitness was to help people, and part of this includes educating them about how their bodies work, and how to manage their weight realistically and safely.

What he hopes to prove is how dangerous many weight loss crazes can be, and that they are not sustainable in the long-run.

I think unfortunately weight has been used as if not the only metric one of the main metrics to describe physical appearance when really it should be much further down the list. Numbers on a set of bathroom scales aren't going to tell me how good the food I'm eating is or how much exercise that I'm doing - it's essentially telling me my relationship with gravity.
