 Interesting. So your body is always adapting to what is available. How do carbs influence hydration? I think that’s the tricky part for me because I’ve heard insulin spikes affect your electrolyte balance. 
 Glucose helps transport sodium and potassium molecules into cells. 

Btw, a common misconception is carbs = insulin (and insulin = bad). Proteins are insulogenic too, often even with a higher insulin response. Whey for example is VERY insulinogenic but still promotes fat loss.  
 So how do you know how much carbs you should eat? Carbs like fruit don’t seem to have the same satiety signals as fat/protein. 

And I know about protein causing insulin spikes too. They are smaller spikes but I still find it funny that the reasoning against carbs is based on insulin. 
 It's not that easy to answer as it comes down to genetics. Africans for example would need more carbs than northern europeans. However, at least 150-200g should be the minimum for everyone. A good start would be a 33:33:33 approach — one third carbs, one third protein, one third fat. From there you can individually test if your body prefers more fat or more carbs. (That is, however, when you dont have insulin resistance which tricks your body in prefering fat.)  
 What kind of signs would you look for? headaches, fatigue, diarrhea? What would you do in response to those?
