If you did Tae-bo for one hour a day and you weighed 127 pounds how long would it take you to lose a pound?

If your ate exactly the amount of energy your body uses (not including Tae-Bo) then it would take around 7 hours of Tae-bo to lose one pound of fat. However during this time it may be likely you gain 100 grams of muscle, so the scales will never reflect fat loss 100%. The formula is: 1 pound of fat loss requires a calorie deficit of 3500 Calories. 7 hours of tae-bo at approx 500 Kcal per hour equates to 3500 Kcal in energy spent and 1 pound of fat lost, while muscle density increasing. IF your heart rate was above 80% Max heart rate fro this whole hour, then you Kcal use will be higher. If you were active all the time and could hold a conversation the whole time (under 70% Max heart rate the Kcal uses will be a little lower. The good thing however is that tae- Bo will increase flexability and muscle tone.
