The article "A limit on the energy transfer rate from the human fat store in hypophagia" states that subjects with moderate activity levels are found to have a limit on maximum energy transfer rate from human fat stores of 290 kJ / kgd. This results in 31 kcal / lbs.
Does anyone know (possibly with access to full article) if above numbers are kJ/(kg body fat) or kJ/(kg body weight)? Optional, the article mentions moderate activity, what happens in the case of high activity?
I asked because if its kJ/(body fat), then this limits a 185 lbs male with 27 lbs body fat to 837 kcal/day metabolized from fat adipose tissue into energy, limiting his weight loss to about 2 lbs/week. If it's kJ/(body weight), then a 185 lbs male can transfer 5723 kcal/day from fat adipose to energy and lose about 13 lbs / week. Rough calculations made where 3500 kcal deficit = 1 lbs weight loss.
I personally fasted without any food, only water, moderate exercise of about 6 miles walking per day, for three weeks and lost about 4.3 lbs/wk (accounting for the loss of 11 lbs material in colon). My own fasting data suggests:
1. I used energy from breaking down muscle tissue over the 837 kcal/day limit (fat store max) suggesting this article calculates using kJ/(body fat weight).
2. I used energy over 837 kcal/day which was 2344 kcal/day from my fat store, not muscle tissue, suggesting that this article calculates using kJ/(body weight).
