No, you probably suffered from nutrient deficiencies, symptoms that went away once you diversified.

A total guess of what happened to you, but what's not a guess is about the adaptation taking months and being about anything more than dehydration or nutrient deficiency being total bullshit.

Cutting out high-GI foods doesn't produce nutrient deficiencies, since they're generally calorie-dense but low in vitamins etc. If anything, the fact that you're getting more meat and veggies to make up for it increases your nutrient diversity, from day one. So again, you're completely wrong.

As for adaptation taking merely days, what's your source for that? The common wisdom and community consensus that you'll read anywhere is that it takes roughly 2 weeks to 2 months to adjust. You're the one claiming this is wrong. So what exactly is your proof here?

Look, I'm glad it wasn't a problem for you. But claiming that therefore it isn't for others, just doesn't hold water.
