Michael Cañas: Why I lost a stone in a day
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.
