I would suggest it is better to look at what actually happens.
Person on 100gm carbs is getting his most of the energy from fat in ketone form. So there is no need for gluconeogenesis of fat. My point was that if the person is not eating sufficient fat then he might experience weakness. Or if his body can not process fat efficiently (rare possibility).
Whatever calculations you are doing are theoretical and may be useful for some but practically not applicable for all.
This weight reduction theory is not for all is my practical experience. Even after unintended reduction of weight by 8kg and so called balanced diet (prior to adopting LCHF diet) there was no control of BS. (I was never overweight contrary always underweight).
Still some questions remain unanswered.
It the test for ketone in urine is negative (on LCHF), are you going to still claim the same thing?
Quote from my last reply to you
"These people try to manage their diabetes with the help of their doctors but fail. I myself initially was doing what conventional medical practice recommends. But to no avail.(For diet none of the doctors suggested me anything)."
You said you have successfully controlled you diabetes by weight reduction then you should post your BS and lipid nos. here.
