Some people really dont feel an appetite increase. Eq can help though! It's known to make some eat their own arms off!
Keep in mind that each individual is different also, some may require fewer calories and some more. I see a lot of guys just shoot for 5000 cals or more and they havent stopped to think about their body and what calorie range works best for them.
Personally, I know my range from what's not enough to what's too much. I try to keep it at midrange.
Anyway, keep stuffing yourself! Mind over matter...
