Feeling full
YOu will not strtetch your pouch this early on. Fluids flow out of your stomach faster than regualr food. Try to follow your centres guidelines and hopefully you will find you are full. Also try waiting 1/2 hour and distract yourself. It may be you are thirsty. Your body sometimes will make you think you are hungry when you actually need water.
Head hungry can rear it's ugly head as well
