So many questions...
Like: when you say "ketone" you mean what kind of ketone/ketone ester...? My first thought when they complained about it tasting like nail polish remover was that if it involves acetone, it is nail polish remover.
Second, I wonder what this would be doing to metabolism of other carbs... I've read that using these ketone esters without decreasing carb intake might actually make things worse from a certain perspective, metabolically speaking...
Not a criticism, just kinda thinkin out loud.
