using slin would be great for a CKD diet.
get into ketosis WITHOUT using insulin...then when you have the weekend carb up, use the slin so that you get maximum glycogen storage to get your muscles full and pumped.
i've heard of guys using slin to get INTO ketosis, but thats so dangerous you could die from it.
other than that i dont see why anybody would use slin for dieting with any other kind of diet.
