I lost a a good amount of weight last year in lockdown. It was through a combination of calorie counting and 45 min workouts 3 times a week when I had all the time in the world for it. The weight melted off.
I stopped last Sept and over the past year steadily gained nearly a stone back 
The calorie counting is unsustainable and I don't want to go back to it as I know I will have to change what I do to maintain the loss. I'd rather start as I mean to go on.
I'm not overweight but I know if I leave it much longer I will start creeping that way and it's a long way back.
I have a big sweet tooth and get very tempted with the contents of the cupboard around 4-5pm. I never really know what to cook but I have 2 small DCs and a DH and it needs to be pretty family friendly as I don't have time to cook separate meals.
If you have successfully kept weight off over a long period of time without having to exercise 3-5x a week what did you/ do you do that works?
