If you want to calculate the energy of 3kg of fat it's much more simple, 1 gram of fat is 9 calories. 9 x 3000 = 27000 calories (111000kJ)
Just a few reasons your calculations are soooo wrong:
Firstly, that equation has no connection to energy stored in fat
You assume all energy is being released at once
Your not accounting outside influence
Other than the equation not making sense in regards to what we're discussing, your also calculating the wrong the factor. Fine you got some energy number, but what would you use that to? We're discussing heat, which is a form of energy. What you need to find out is how much energy it requires to sustain our body temperature, this includes outside variables such as wind speed and outside temperature.
The fact of the matter is, any metabolic process in our body produces some kind of end product. Mostly one sort of energy is being converted to another. If we're in a caloric surplus, our body stores energy in fat cells, this energy is then released when we're in a caloric deficit, it is being released to serve a purpose and the fact is that whatever this purpose might be the end product generates some kind of heat.
Of course, it's not a one-sided story, some ends being exhaled (in oxygen to carbon dioxide process), some gets urinated (through fat cells being used in the liver and metabolic processes), but these are a small part of a major system constantly in the works. Even when we exhale, urinate, excrete the process to make us able to do these things produce some kind of heat, all that work adds up to much more heat than the energy used in each seperate variable.
Another edit: Assume your calculations were true, imagine how much a person would have to eat to gain 3kg in a week or two. With that thought, its absurd to assume what your saying has any truth.
Just on a side note to people saying you shit out fat. That is so wrong. Your body burns fat cause it's needed, not just to get rid of it. That would be like throwing out leftover food supplies when people are starving on a cruise. You feed it, don't throw it out.
