Hi,I had a week or so where I was permanantley hungry,I kept drinking and drinking in the hope it would fill me up,my stomach was rumbling like a good un,my cdc said the rumbling is a sign of a healthy gut,we never came up with an explanation though!Dont know if you have had chewing gum that does it with me about 2 hrs after ive chewed it.some people say the bars can make you hungry,I dont get that,just to let you know though youre not alone,sometimes I get hungry for no reason atall!
