Eating is a stress on the body period. LC is a stress, high fat is a stress, high protein is a stress, no food is a stress, too much food is a stress, normal food is a stress.
Tho normally this stress is fairly insignificant, it can become significant if the body has to deal with the same stress over prolonged periods (chronic).
Here's the caveat; this stress can vary greatly. Eating C's or F's or P's might hold different levels of stress which could vary per person. Eg if paleobird finds eating carbs more stressful then eating fat and protein (even tho these can be stressful long term) then it is logical that a high fat and protein diet is the suitable option for her.
If derpamix finds that going keto (high F & P) is a major stress than going high carb, eating alot of carbs might be a valid option even tho high carb is going to cause trouble long term if he over does it.
It is my belief the default least stressful mode of eating is gentle cycling of macro's and cal's of nutrient rich food so that your diet averages out. As I alluded to in my first post tho, tweaking your diet outside of these parameters might be necessary (eg LC because of keto needs).
OP eat however you like, with lots of experimenting, just understand that LC is not necessarily (for you at least) the least stress full way of eating, wich can be a common misconception on these boards.
I am most definitely not, a Peat loving LC basher tho.
