I have also dropped 40lb, gone from 20/22 to a 16. Have kept it off for 2 years. I might up things a bit to lose some more, I might not...
What worked for me was the "why the fuck am I eating now?" plan, to begin things... beginning things is the hardest bit.
We know that we eat breakfast/lunch/dinner to get nutrients, keep up energy levels etc...
Get up, have breakfast... any breakfast... cereal, toast, eggs, yoghurt with fruit, whatever. Then don't eat til lunchtime.
If you reach for food before then, ask Why? Hungry? Thirsty? Bored?... do something mind consuming... and have a better breakfast tomorrow.
Then for lunch have a sandwich and a bit of fruit. Something "everyday" and boring. Familiarity stops craving, my big problem was not having the sandwich and fruit, it was the HABIT of having them AND the grab bag of crisps, and the chocolate bar, and the biscuits mid afternoon...
Again in the afternoon ask why if you need something else. Add more stuff that is good for you in lunch if actually hungry.
Then have a standard tea , something you usually eat but less of it, not a lot less, you want to lose weight slowly but surely and not be hungry... as you lower carbs/meat increase veg and you soon feel the benefit.
In the evening I don't eat after 7... acid reflux gone. No longer need an acid suppressant, I digest what food I do eat better, my gut is healthier, many benefits.
I am not a qualified nutritionist. I cannot abide counting or replacement foodstuffs, but have found what works for me.
