For men this amount is roughly 5% of body weight, for women it’s closer to 13%.
Admittedly I have not explored the science behind these numbers, but for the purpose of this blog post, let’s assume they are correct.
(I also find basing the essential amount as a percentage of total body weight as opposed to a percentage of leanbody mass to be odd…but I digress.)

Then as a ’safety cushion’ let’s assume enough fat to provide 2 weeks worth of energy should I need it.
