Subject: RE: Bike Gurus: Bike power and weight loss/gain The powermeter will allow you to compute actual kcal burned per workout, with software like GoldenCheetah, and I think, Garmin Connect. The same principles of calories in < calories expended still apply. IMO, the powermeter doesn't make it any easier to lose weight; even if you know you burned exactly 1800 calories in your last bike workout, you still have to control what you eat relative to hunger, so you'd likely have the same weight reduction by just tracking time spent on the bike even without power and trying to bump up bike time. You can actually get close to powermeter estimates of calorie burn in running by just using online calculators where you plug in your body weight and distance run, since in running, it's pretty stable calories/mile regardless of pace. If doing something like that doesn't make a big difference in your weight loss, it's unlikely that having the powermeter calories burned number will. |
