Most on keto find that being high fat .......they actually feel fuller longer. Unlike carbs (particularly moderate to high Gi carbs) whereas the convert to glucose faster and end up leaving you hungry quicker.
5-7 meals a day of high fat, and fiberous green veggies for the majority of your carbs (excluding PW, of course) and you shouldn't be hungry.
Did you just come off a bulk bro ?........maybe you just so damn used to eating like a horse. LOL
