What is the density of the stored energy in adipose tissue (body fat)?

  1. Jul 14, 2011 #1
    I think the title is self-descriptive. This question stuck in my mind. I want to learn how much energy is stored in human fat.

    Does this amount of energy density change in every human?
    If so what is the variance of this distribution?

    According to this wikipedia page on Adipose Tissue, it is 80% fat. Assuming this value is a percentage by mass, and using energy density values from this site, energy density of adipose is 0.8*37.7= 30.16 kJ/g

    I don't know how this varies among different people, nor could I find any studies regarding this question.
