I know how you feel. I think what has helped me most is being on a thread on here, and listing my food intake each day, and also signing up to myfitnesspal.com which tells me the calorific worth of everything. I was shocked at some things, I really had no idea what was calorific or not.
2 stone is not a great deal to lose, you can totally do it
I love baking I love eating what I bake I love cake and biscuits
Afternoons are my weakness, I deal with mornings by going out so I can only eat what I've taken with me (I'm a cheapskate so rarely buy anything from the shops) Afternoons I seem to eat from lunch til bedtime and I find it very hard not to. I've lost all concept of stopping when I'm full.
If you like veg could you chop up a load of it and keep it in the fridge so there's always something there? Make some salads up and not put any dressing on so they last longer and then they're there when you need something. When you say you don't really like fruit - there is a huge variety of fruit around, is there really nothing that tempts you? I keep a bowl of apples/pears/bananas/nectarines/oranges/grapes around so I can have them if I have the Irresistible Munchies. Could you get rid of anything (crisps/nuts) that you get carried away with and just not have any in the house? I've stopped buying biscuits so if I want one I have to make them myself and I usually don't have time.
I understand about the self-esteem, I feel crap about my body at the moment and have no motivation.
Definitely agree that if it's not in the house, you wont eat it. Shop when you feel particularly motivated to get in healthier choices. It's fine to snack if your meals are smaller too. 6 small portions a day is ideal, I usually only do 4-ish. You can fix this because you have done the hardest bit - working out why/how you came to be overweight. So many people just 'have no idea' how it happened. Chopped up raw veg in the fridge to dip in hummus is a salty snack that can replace crisps in terms of that savoury craving that usually ends in crisps. But if it isn't pre-prepared, you wont want to bother. Also, hardboiled eggs in the fridge - the white makes a great snack. If I pre-prepare food, I don't want to waste it, so I feel I have to have it which leaves no space for crisps etc.
Oh I second myfitnesspal. It's fantastic and you can link up with friends for some accountability. My sister and I love it (not so much when we get messages from each other laughing at each others food diaries...)
Why would you be attacked? First step is recognising you need to do something. But if you have a weakness for crisps and pizza, well don't buy any, they are hardly essential foods! If you know you'll grab what you see, make sure lots of healthy snacks around.
If you are looking for something to improve self esteem and willpower than I suggest "Adore Yourself Slim" by Lisa Jackson.
