Actually, you're well off, but not for the reason you think. Let me explain.
Fasting invokes all your counter-regulatory hormones: cortisol, adrenaline, others but they are the big players - because not having easy access to sugar leads to a stress response.
So it isn't gut rest, it's physiological phase change that is causing the stress response
- agumonkey 10y agoHow long is the stress response ? is it only transient before switching to a "fasting" regime or is it long lasting ?
- robbiep 10y agoI guess depends on your definition of a stress response; most people would consider it to be a 'stress response' whilst you have high adrenergic/sympathetic activity. Upon activation of the parasympathetic nervous system there will be a gradual decrease in cortisol and a rapid decrease in adrenaline. Thyroid hormone is also going to be implicated somewhere along with a host of other hormones so I have simplified but suffice to say it's shades of grey on the way in and out
