I started Lighter life last January weighing over 16 stone with a BMI of 38. All I got was its too drastic, you will put it all back on, you will not be able to do it. I got pity in restaurants even though I sailed through and never cheated once, it seemed more difficult for the people I went out with than for me. Once I lost three stone, everyone kept telling me how good I looked. At 11 stone last year, all my in laws and "friends" convinced me i did not need to lose any more, even though I was a stone short of my target I stopped due to the peer pressure, and because I had done 6 months solid. At Xmas I weighed in at 12 stone 4lb, so had put a bit back on, and when I found Ann (Westhills), all my in laws tried to convince me I was mad, and did not need to lose more weight despite my BMI being 28.
The long and short of it is, that once I decided again that I wanted to lose more, I have not faltered and have now lost almost a stone, and fully intend to keep going until I am happy.
I know with my in laws it was a case of the women in the family always seeing me as "the fat one" so to them I do look slim now, but not as slim as I want, so it has to be what you want to do.
