2 I suspect you're trying to simply cut out "bad" foods and not replacing them with anything - that's a mistake you'll get hungry and resort to old habits.
You need to replace what you're omitting with something of a similar flavour profile
So if it's sweet something sweet (cereal bars, fruit, yogurt, lower cal biscuits depending on your preference and fewer of them IF you have the willpower - which is HARD especially at the start)
If it's salty (crisps for me are a particular weakness) then something lower cal but also salty (popcorn, I also like carrot batons which I pop in a wee food bag and season with garlic grinder or paprika or black pepper or just salt - then hold the bag closed and shake - like salt and shake crisps except veggies! Also works with celery, peppers, cucumber etc and very tasty, lower cal "crisps" type snacks I'm partial to Twiglets and frazzles myself)
If it's spicy then something lower cal but still with a lot of spice, (the aforementioned seasoned veggies with some chilli flakes or with a spicy dip like a salsa or lime chilli type thing, pickled chillies, cauliflower rice spiced up)
There's a theory that we eat the same VOLUME of food according to our height but that those of us who are heavier make that volume up with more calorie dense foods
That perhaps sounds more complicated than it is - it's easier to eat 300 cals worth of chocolate than 300 cals of lettuce! The lettuce is less dense calorie wise so you'll feel full eating a lot of lettuce but be consuming fewer cals than with the choc.
I'm not professing to be an expert I've a long way to go myself just sharing some stuff that has helped me in the past I lost a couple stone with ww some years back still have around 4 stone to lose. With the support of the above mentioned thread (which has "members" who have reached and maintained a healthy weight) last year I managed to lose 1.5 stone ish from June to December - then I had some personal issues and it went to hell BUT I didn't regain all of it and through that journey I know now what works for me. We all use different techniques and methods, the posters are lovely and kind and funny people who never judge.
