I started intermittent fasting around 12 years ago, I started off with quite an extreme calorie intake (around 600 cals per day) for a couple of weeks, which was brutal, but after that I just didn't feel hungry, so while I was hungry just before my two mealtimes, I didn't feel hungry after. I lost 7 stone over the space of a year, and to be honest the weight just fell off, but after a while I knew exactly how much to eat and when, I portioned my meals and didn't snack at all.. if anyone offered me anything, I would check if I was hungry or not, and if not I wouldn't have it, no exceptions. If I didn't pre-portion my meals, I always stopped before I had finished and got attuned to the 'full' feeling that meant I'd had enough. I always went to bed early and slept about 9-10 hours.
I put about 1 stone back on over a couple of years, when I met my DH but was still happy with how things were and stayed around that weight, I had stopped fasting but still restricted my portion sizes, still didn't really feel hungry.
Then I had my daughter, who is three now, and never really lost the baby weight, my portion sizes increased over time, I started eating chocolate and sweet stuff again and I've struggled with it ever since, eating her leftovers and DH eating a lot and snacking a lot (he burns it off at work) has given me bad habits, and now I only have around 5-6 hours sleep, that's a lot of awake time to feel hungry!
I've been back fasting since last sunday, but weirdly lost no weight the first week, I feel different though, clothes are feeling a bit looser, if I can stick to it I KNOW it works, but the cravings in the evenings are getting to me a bit and when I feel tired I want to reach for the snacks, I'm determined this time though, we go away in Mid May and I want to not cheat at all with the fasting before then if I can do it!
