I have about 21 lbs to lose to get back to the size 10/12 I have been my whole adult life, but last 3 years I've got into some real bad habits...at night only! I eat well throughout the day, generally cook a healthy dinner (I love cooking and love healthy food) and I'll even go for a swim after. Then I come home, plonk on the couch and turn into a potato! I just want to nibble all night till bedtime and I have no idea why. I don't have the urge to snack throughout the day. I go swimming to try and 'fill' the evening and for exercise, but I can start snacking after from 9.30pm onwards. I do actually get hungry though, whether I swim or not. I can't go to bed before midnight as I can't fall asleep otherwise I would go at 10!. My age is maybe against me now (at 56) as I've read your body does change and you do store more fat when you get into the 50's age group? When I look around I would say more than 50% of over 50 year olds are quite overweight. I would like to know is this nibbling just a habitual thing with me or could it be a chemical change in the body after menopause?
