David Sameiro, 31 was suffering from joint aches which meant he couldn't lose any weight, but that was then and this is now. He simply changed his insoles in his shoes and walked off 20 stone to get to a more desirable weight. He started walking everywhere and made it his mission to lose weight by being more active and not just sitting around. The retail manager now weighs 13 stone and looks great, well done David, excellent job!!
