I've never dieted but I think what I eat would be considered "a diet" to many of my heavier friends.
I eat 3 meals a day, comprising of home cooked food with a lot of veg. I don't aim to eat low calorie, just honest good quality, satisfying meals but if you cook real food, even extravagant, savoury meals are unlikely to be more than 700 cals.
I very rarely have anything with refined sugar, I gave it up years ago and it's made a huge difference to my PMS.
I don't snack. I exercise most days, my sport is very important to me.
I love food, but good food, I genuinely don't want junk, although I suppose that has been a gradual process that came about with giving up sugar.
This is just the way I live. I don't do it to be slim, if there is a reason, it's to be fit and strong for my sport, but mostly it's just normal to me.
