Revisiting the Bulletproof Coffee Experiment Once More --What went wrong?

The experiment:

Drink Bulletproof Coffee for breakfast - nothing else.  Eat a regular lunch and dinner.

Bulletproof Coffee contains fats (butter and MCT oils) that are purportedly healthy and help you improve your metabolism.

The theory (in brief):

By consuming fats and not eating carbohydrates or proteins, your body will utilize stored energy from fat for fuel.

According to what I've read about Medium Chain Triglycerides, the MCT oils cause the pancreas to produce insulin, lowering blood glucose.  The liver then should respond by breaking down stored glycogen to glucose, maintaining the blood glucose levels within a normal range.

So, what went wrong?  Why didn't my body compensate for the lack of nutrition by creating glucose?

I've done some research, and the answer I've come up with is:  I don't know.

Possible answers:

1)  My body, although healthier now that it has been in the past, is still suffering the effects of years of the SAD (Standard American Diet) and my hormones may be imbalanced and not working altogether the way they should.

2)  Everyone is different genetically, and what works for one person may not work for another.

3)  Women are biologically less likely to benefit from fasting.  (Mixed results in the searches I've done here).

4)  I have been essentially caffeine-free for several months.  The addition of significant amounts of caffeine caused a signal to my adrenal glands that I needed adrenaline (a stress response).  If my adrenal glands are lacking, due to adrenal fatigue and stress, they were unable to produce sufficient amounts of adrenaline to raise the blood sugar, resulting in hypoglycemia.


I suspect is may be a combination of health and heredity.  In any case, it will be a long time before I want to try this experiment again.

My husband, on the other hand, seems to be doing okay with the plan, although he does still get hungry by lunch time.  He has been drinking coffee after I quit coffee, though, so there may be some differences there.
