Grams of fat lost during cardio

[bosketaru]

OK, so while I was doing my cardio tonight I was thinking how many grams of fat I was burning.

I did 45 mins at 3.0 mph.

1st 15 mins - 9.0 incline
2nd 15 mins - 10.0
3rd 15 mins- 11.0

Total calories used: 365

Say, for the first 15 mins (before my body starting using fat as a energy) I used about 115 calories from carbs. Theoretically speaking, the rest should be fat calories, about 250. So 250/9= 27.7 grams of fat per cardio session.

Is this right?

9 calories per gram of fat - look at fat calories 90 calories from fat would be 10g of fat.


simple math.

3500cal are 1 lb of fat. Go figure

It's not the math that I'm asking about, its the concept of actually losing that much in a cardio session.
