does anyone know the breakdown of calories burned at rest? Fat/Carb/Protein? I'm sure it varies for the individual and diet, but is there kind of a "rule of thumb"? Thanks.

Resting Metabolic Rate is what I think you are referring to. This would be the amount of calories your body's metabolism requires for daily function. This does not include any additional activity. The quick method for determing RMR is to take your body weight and multiply by 10. To calculate your TDEE (Total Daily Energy Expenditure) you take your RMR and multiply by the following factors:
sedentary RMRx1.3
lightly active RMRx1.4
moderately active RMRx1.5
highly active RMRx1.65
super athlete RMRx1.75
these are pretty close estimations.

at rest, the body prefers to burn almost exclusively fat, as you heart rate and intensity of whatever you are doing speeds up, you body begins to favor carbs, and once you are anaerobic, you body is using exclusively carbohydrates and your ATP-PC system.

Luke, I never knew that. Wierd. I always thought that your body burns carbs as their primary source of energy regardless of what you are doing, then resorts to fats if you are out of carbohydrate energy. Why is that then? That's definately better though, burning fat at rest. Also, what part of Chicago are you from? Peace.

Oh sure yeh same with low intensity exercise if you aint supplying oxygen to your mitocondria you will burn fat thats why alot of ppl choose to do there cardio at a slow walk for a longer period of time because they burn nothing but fat.

Anyway... that's just s simple explanation. it's a bit more compleicated. low intensity exercise does burn primarily fat, but if you do have carbs in your system, you will not be in a state of liposis if your intensity is too low. this is why I like HIIT, since the carbohydrates you consume around it do not supress liposis, and in the end, you lose a greater amount of fat because your metabolism is elevated for up to 6-12 hours after your workout, where as low intesity exercise does nothing to raise RMR, and therefore, at rest, less fat is burned.
insulin completely supresses liposis during low intensity exercise.
