Allgoingtopot I find intermittent fasting combined with generally avoiding processed carbohydrates very simple and freeing. My only strict rules are that I always have a minimum 16 hour fast in every 24 hours - times are flexible but whenever I stop eating (whether 6pm or, rarely, 11pm) I know I won't start again until 16 hours have passed, and that I only eat processed carbohydrates if they're worth it and only in company. That means I might have an ice-cream or pizza with my kids/ family but will never eat a bar of chocolate on my own again. If I really want one I guess I'll share/ buy one for everyone/ someone else and we'll eat them together
In all honesty it just removes the vacant/ purposeless/ binge/ emotional eating.
I cannot be doing with calorie counting or avoiding vegetables which contain carbs, anything requiring counting or anything too inflexible is something that I'd rebel against.
You have to find out what suits your body and your temperament and also your lifestyle.
I've lost 7 stone and am maintaining by basically just carrying on with the same thing, but doing mainly 16 hour fasts rather than mostly 18-23 hours, and playing the flexibility by ear. I still do 23 hour fasts sometimes if I know I'm having a big family meal/ restaurant meal.
It suits me because nothing is forbidden, it's very flexible and I don't have to over think or obsess, nor do I ever have any need to make a song and dance about what I eat in company - important to me.
I'm maintaining near the top of my healthy BMI because that's where I want to be and where I feel good. I feel very strong and healthy and have very defined leg and oblique muscles from a lot of walking/ hiking; I still have a slightly wobbly tummy, but having had 3 caesarean sections I am very much at peace with that!
Good luck! Hope you find your way!
