Google tells me that 1lb of fat is 3500 calories. That's pretty much a lax 5 hours of the elliptical every week. Give it a year of persistence and regular hydration you should be able to lose 52 lbs a year if you maintain the same caloric intake which I wouldn't recommend because you'd probably want to be eating what your body needs to recoup. But realistically you could probably lose 20 lbs over a year. Maybe more depending on your basal metabolic rate. I lost 10 lbs by moving more. Much more... It's been a lifestyle change but atleast I don't feel bad about sitting around
