I am 29, 5ft 8" and weigh approximately 12st 10lbs (will weigh in properly tomorrow morning to check). I have struggled with weight a bit, not excessively just a stone or so over my "ideal" weight over the years (losing it, gaining it etc). I weigh the most I have ever weighed at the moment which I think is somewhat due to having an issue with a labral tear in my hip, for which I had to stop all exercise (I previously ran, played competitive hockey, swam and walked our dogs). 6 weeks ago, this was operated on. I have been off my feet more or less since and am looking forward to banishing the extra pounds I put on from comfort eating when bored/in pain and lack of exercise.
Although my physio and surgeon have not cleared me for any weight bearing exercise yet, I hope to start managing my food consumption better and perhaps add in the exercise later down the line when I am off my crutches and in less pain.
The NHS BMI guide suggests that I might want to aim to lose 2st 7lbs as this would put me smack bang in the middle of my healthy BMI range. Which would be 35lbs across the 12 weeks of the plan, so a goal of losing about 3lb a week would help me to reach that target. I think even if I only lost 2st or 1st 7lbs, I would be much happier as my clothes would fit and I would be back to my pre-hip weight.
I guess my main goal is to reset my eating habits for the long term. I eat quite a lot of "packet" or "pre-prepared" food such as pizza (which is a favourite of my husbands) and bread/cake/wheat type stuff. Although, I do make our own chips using potatoes, sweet potatoes and frylight in our halogen oven, and we eat a lot of veg although not a wide variety (sweetcorn, peas, peppers, mushrooms, tomatoes are pretty much it - and its taken me a long time to get my husband to eat those!).
