Recognising you have a problem is a very good start!
Try to decide why you're overeating, you know, the usual things like boredom, stress, anxiety, poor self-esteem, self-control issues (can you 'stop at one' when it comes to biscuits, for instance?). Do you graze all day? What sort of foods do you have to hand at home? Do you do any exercise, and if not, are there reasons for it? Each time you reach for food, ask yourself 'Why?'. Can you stop eating when you're full or do you need to clear the plate?
Decide on a strategy, be it 'proprietary' like WW, SW; or a system like 5:2, or calorie counting. Different personality types find different styles suit them.
DO you have family around you? Get them onside; like say to DH/P 'Please don't offer me snacks', to the DCs 'Please scrape uneaten food into the bin'. Practice always leaving a bit of food on your plate. Examine how you eat- is it always sitting down at a table? Put your utensils down between each bite. Make yourself chew everything and focus exclusively on the food. Try and hear your body's 'full' signal.
Recognise the feeling of hunger as your body saying 'OK, now I will have to burn fat, not the contents of the last meal as it's gone!'
Learn as much as you can about it; obvs on MN is a good place to start!
Set a 'start date'. In the interim, either chuck out or, if you can't bear to, eat the stuff that won't be useful to you in a weight loss diet; remove temptation at least at first.
I am no poster-girl for dieting! I weigh 11/11 and am 5 foot 6 (BMI of about 27). I weighed 13 stone at my heaviest, was stable at 11/10 for a while, crept up to 12/1 ('planned' as I had a stressful fortnight with the in-laws and I knew I couldn't keep my weight loss programme going through that) but I restarted my weight loss a week ago. I am aiming for 11 stone initially.
I am a "boredom/ 'because it's there'/ treat myself" eater. I also rather like the pinot grigio (
). I don't like getting hot and sweaty.
I decided 'fads' weren't for me. I know they are for some people and the term 'fad' might offend but I feel that what you do to lose weight has to be sustainable forever otherwise it won't work. I don't think I could count WW 'points' forever, for instance. I started with Paul McKenna ('I can make you thin') which I recommend; I learned about GI and GL foods; about the role of exercise in permanent weight loss, the use of soups and protein. I also examined my portion sizes!
I have also looked with interest at 5:2 but I think the elephant in that room is the fact that for us to get overweight, it's because we eat way more than the 2000-2200 a day we're supposed to be eating, so on our 'non-fast' days, we'd still be hoofing down 3000+ cals which, to me wipes out the 'gain' (and pain!) of the fast days. I think 5:2 would work better for me once I am lighter via keeping to 2000 cals a day. There are also a stack of other health benefits to intermittent fasting, too.
Exercise. Yes, one must. Allow yourself to hate it, if you do. I do! It's OK because I can see it as a thing I have to do, like brushing my teeth or getting a smear done (sorry!). I have an electric treadmill and I aim to walk fast on it (3.8mph) for half an hour 4 times a week, watching the telly. I know I will get all prickly and sweaty but I have a shower straight afterwards, and I know I have burned 150 odd cals, the effect of which stays with my metabolism for up to 24 hours.
I am currently calorie counting because I am on a 49 day diet (til the DCs summer hols) where I aim to lose 2 lbs a week. I am being strict with myself and know this isn't sustainable in the long term but once I hit 11 stone, I shall consider 5:2. I record my calories on MFP.
Final advice is to find a board on here that you like and to get support on it. There are lots of people here in the same place as you!
Best of luck.
