Yup, I have always suffered from this, and have recently lost 150lbs, and have tried every diet possible over the years, but ultimately, it is just about reducing calories and sticking to it over the long term.
Addiction to food is unfortunate, because you can't cold turkey food
- when you eat you are going to be tempted to binge, even if its not very nice food, because it's still food, but what I can say for sure, is that the delicious foods (chocolate, ice cream, pizza, crisps, peanuts, cakes etc) are going to be seriously problematic for you. Those need to go, imo, completely.
As mentioned by the poster above, when you restrict calories, know that
you won't be as hungry as you feel forever. In my experience it takes a week or two tops at a lower calorie range and your body does adjust and you get used to the lower food intake (hunger wise). You will always have the urge to binge though, at some level, but you just need to accept it and manage it.
For general weight loss, use myfitnesspal and log calories (be as precise as you can for a while, weigh things etc until you can eyeball well). You need to do this because your brain and body will lie to you otherwise (I estimate typically 500-1000 calories less, if I don't log) . You are a woman so calories will be lower than for a man, (this will depend on height as well), but say, 1200-1500 calories (assuming you are 5ft6 ish) should give you a good rate of weight loss (if accurately measured). Measure accurately, set an average calories, and weigh yourself once a week. If you don't lose weight after 3 weeks reduce average calories by 100 (and ensure your weighing is accurate). If you do this you will lose weight,
guaranteed.
So some tips, generally speaking and w.r.t. food addiction:
1. Monitor calories
2. It takes a week or two to adjust to lower calories (but you should adjust and hunger decrease)
3. Remove hyperpalatable foods from your diet (chocolate, ice cream etc).
4. Don't have any delicious foods in the house (important)
5. Don't go food shopping when hungry
6. Do whatever you have to to get through the first few weeks. I would give my car keys to other people overnight so I literally couldn't drive to the shop to binge on junk food. When the first few weeks pass, and you have a string of low calorie days under your belt, and weight is shifting it will be easier to be disciplined.
7. Reduce willpower taxation as much as possible.
Re number 7, you don't want to rely on willpower, you want to put in place things which prevent you relying on it at all. This is especially important when you start out and jump to a lower calorie range.
Good luck
