"What's the first thing you Notice? "
"You're NOT hungry.
Indeed, how could you be? Ketosis, just like a fast, always induces appetite supression once the body's two-day supply of glycogen is burnt off.
Two days are past. Your glycogen is gone. You're solidly into Ketosis/Lipolysis. At this point, you're finding out that this appetite suppression if the MOST STRIKING THING that has ever happened to your appetite in your life!.
Suddenly you find yourself eating quite moderate quantities of food and feeling no hunger pangs.
You certainly know you're in ketosis, when you find yourself saying: ""You mean lunchtime was an hour ago?"" "
This is ketosis!
