Plus one here for a positive keto/low carb experience.
After several years of forgoing wheat through necessity and replacing it with other carbs (spuds, pulse, rice etc) I have recently ( for a few weeks) taken up a low carbohydrate diet and had very good initial results.
They are weight loss, better sleep, no hunger spikes/hangry episodes, better mood, no crashing exhaustion. An almost total disappearance of arthritic type pain in various abused joints.
I'm really thrilled with the results thus far and although it seems counter intuitive to all my past learnings on nutrition, I really am now convinced there is something in this.
I will, however, keep a healthy dose of cycnisim going forward, but right now the brilliant results are like some kind of voodoo.
I suspect that diets are not a one size fits all, but I think its very likely that I'm one of the many people out there who do not do well on a shit tonne of carbs. That does make a little bit of me sad!
I haven't reduced my very liberal wine consumption either. That makes me very happy.
