most of us do sedentry work, sitting and working on a computer, light walking, driving etc... which does not require many carbs, when does the body use fat for energy? Like wise carbs?

Good question Id like to know this too, but I think the answer may be when you overload your ATP requirement so your body starts using fats/carbs/proteins to make up for the deficit. Hopefully someone can clarify this.
bump, anyone?
Morning cardio on an empty stomach?

I'm no expert, but I'll post what I do know. The body starts out breaking down ATP (tri-phosphate) into ADP (di-phosphate). The body can use creatine phosphate to recycle the di-phosphate back into tri-phosphate so that it can be used again. This is why creatine can let you work out longer without suffering from lactic acid induced cramps. Latic acid is a natural by-product of burning glucose.
After the ATP cycle is used up the body starts burning up glucose stores for energy (carbs).
From what I understand the body cannot use Fat to perform annarobic functions like weight lighting, sprinting, ect. It will either burn glucose stores, or break down protien into glucose & then burn it (you DONT want this, so be careful on a low car/low fat diet) But the body can utilize fat for aerobic functions like jogging. So if I remember correctly you want to keep your heart rate from getting so high that your burning sugars, but high enough that your burning fat. I think the sweet spot was like 165 bpm, but I'm not sure, so you might wanna check that.

there is a pre phase to the energy cycle? I thought the body uses carbs, fat, then protein. Basic sedentry work does not even use carbs?
