josie1, I don’t think that our stomachs actually shrink, but it certainly can feel like it does — most of the time this is helpful, although if you have trouble getting enough to eat, maybe drop back to 5:2 for a while?

josie1, I feel similar. I am doing 4:3 and have noticed that:

1. I feel full quicker
2. I don’t need to overeat on non-fast days
3. (most importantly) I don’t feel the need to eat sugary foods (I have a very,very sweet tooth)

I used to always carry some fruit in my handbag to counter any sudden hypoglycemic attack but I have never had one on a fast day (I just get hungry). After a fast day my body just wants to eat good food (fruit, vegetables and protein) to make up for the nutrients lost the previous day – no real craving for sweets and chocolates. I would think that part of my weight loss is this curbing of sweet foods since I don’t eat big portions anyhow. I just love a bar of chocolate or a piece of cake and bread every day.
This in itself is a reason to do intermittent fasting, making you choose better nutrients.

I am in my fourth week of fasting, usually doing 4:3 with consecutive days. I also feel as though my stomach has stunk quite drastically and am a little worried. I can barely eat anything both on my fast days and non-fast days! Last night (fast day) I only managed to each half a bowl of soup and even had to force that down as I felt so full.

I’m noticing that i feel full too on non fast days. I log my cals on My Fitness pal, just as a guide, and i’m always surprised i stay well under what i’m ‘allowed’ to have. I alos rarely feel really hungry on the day after my fast day. I tend to feel hungrier 2 days after, not sure why.
