I can't see how that belt'd work in one hour. I started a new job on the 20th Jan this year, and coz of the location, inclusive of the 20th, to 2 March, I went from 15.5st. to 14st. (And counting, hopefully). That's lighter than when I was in my last job. I calculated I must walk around 25 - 30 miles a week, excluding weekends. Why did I tell you this? Well, it's proof you don't need gadgets or whatever to loose weight. Nor even 'proper' exercise

(PS, I put on all that weight coz I was between jobs for 11 months.)
