Calories Burned: Muscle vs Fat?


How many kcal does one kg( or pound) of lean body mass burn compared to fat?



I've heard that just existing every pound of muscle uses 50 kcal/day.
I don't think fat burns any calories.


a pound of muscle uses about 8 kcal per day

contrary to popular belief, fat (like everything our body is made of) is a metabolically active tissue and uses about 3 kcal per day and pound

even though those numbers seem small, consider the cumulative effect over long periods of time
