Ever wondered where the fat goes when somebody loses weight?

You might be surprised by the answer....

When somebody loses weight, where does the fat go?

Re: Ever wondered where the fat goes when somebody loses weight?

Im confused.

I thought CO2 combustion only happens with "glucose" oxidation and not with beta oxidation?

To monitor ones CO2 output vs O2 input we can calculate how much of his energy comes from carbs and how much from fats, this suppose to be a well established method?

So if they (in the video) are saying that fat goes into water+CO2 that would mean it were carbs used for that energy?

So fat is first converted into carbs via gluconeogenesis?
