Lifestyle change really - no faddy diets, just treat your body kindly and put good stuff in it 80% of the time. If you eat a lot of veg and fibre the sugar cravings go. And move a bit more.
I've lost a stone and a half in a year - slowly, by making sure I eat lots of veg, some protein and some sensible carbs. So rice with some extra veg in, sourdough bread, or noodles. Very little pasta or potatoes compared to what I used to eat.
I rarely eat takeaways (twice a year), eat out about 3 times a week. Rarely have ready meals.
I don't drink any sugary drinks.
Massively cut down on alcohol as it led me to stodgy eating the next day.
Cut down on eating after tea as snacking after having my evening meal was a big issue.
Breakfast - poached egg on sourdough toast with cooked tomatoes or avocado. Or omelette or fruit and full fat yoghurt with nuts and seeds.
Lunch - usually a salad - so beetroot, feta, walnuts, red cabbage, tomatoes and some lentils from a pouch. Or a home made soup.
Dinner - salmon stirfry, grilled chicken, with some carbs and salad.
I make a few big salads then mix them up in the week.
It's an 80/20 thing. Most of the time I cook from scratch. But if we want a Coop pizza we'll have one - but usually add some veg to the top and with a salad.
it's a change, but honestly the first stone and a half has been pretty easy. I'm more concerned about the next stone and a half!
