Why is blood glucose elevated when fasting?
It is a normal phenomenon that occur due to the falling of inslin and the rising counter-regulatory hormones including increased sympathetic tone, noradrenaline, cortisol and growth hormone, in addition to glucagon. These hormones are then respnsible for releasing of glucose from liver into the bloodstream that is why your blood glucose is high during fasting.
When combining keto and 5:2 intermittent fasting on fasting days, do you still follow the macro guidelines for keto?
On the two days of fasting, should the 500 calories consumed be of the same macro proportions as followed on the normal keto days? Or can you consume 500 calories of any food without going out of ketosis?
There is no need to count calories as you are on fasting!!
Veggies or fat or protein
I think you should eat the salad first. There is some data to suggest that eating the veggies first reduces insulin.
Will fasting for long periods of time activate the famine/fat protocols in the body?
Yes, the psychological part of fasting is hard. Fasting is supposed to be a part of everyday life – that is why we have the word ‘break-fast’. Most people think they can’t do it, but the truth is that people have fasted throughout history. We only think we can’t. As with anything else, it is about getting the right education and the right support group. From a physiological standpoint, fasting allows you to burn body fat, which is a storage form of food for your body when no food is available. This is what most people want.
