I thought I'd start this thread for those who have reached their goal and want some support for a sensible, sustainable way of eating. It may also be useful for those who are thinking about what they'll do when they get there.
Confession: I'm a yo-yo dieter and so don't claim any expertise in this at all, but I am doing things differently this time.
As the thread title says, I'm going to try some fasting (both 16:8 and 5:2), keeping to a low(ish) carb diet, and putting in some exercise.
