Reta is the goat. Glp slows down digestion. GIP improves insulin sensitivity. And hitting glucagon receptor to mobilize fatty acids and maintain glucose levels.You actually need glucose on Reta. Reta tricks your body into thinking you are starving, by depleting liver glycogen stores, essentially making your body start burning fat. You need to get glucose in your system else your brain may quit on you (dunno if it's metabolic) and make exercise more laborious.
