Hi everyone, checking back in. It sounds as if you're all doing really well 
I'm on week 3 of slimming world and after a tough first few days (the sugar withdrawal!) I'm getting the hang of it and feeling good about it. The main rules are low sugar, low fat, very little bread (you can have a small amount of wholemeal bread or other high-fibre carbs each day, the rest has to be counted). Unlimited fruit and veg, lean protein and carbs like pasta, rice and potatoes. So I'm actually feeling really full which makes it totally manageable. For the first time in my whole life I'm managing to limit my intake of treats like chocolate, ice cream etc - I can still have them but obviously can't overindulge. So it feels sustainable. Obviously it's really early days but I'm feeling confident about sticking with it.
I'm 5'8 and my starting weight was 17st10.5, BMI 37.8. I found it difficult to set a target weight because I don't know how I'll look/feel as I get closer to a healthy weight, but my main target is to have a BMI in the healthy range so I decided to aim for BMI 23.5 which would be 11st0.5.
I lost 2 lbs in the first week and 3.5 lbs in the second, so 5.5lbs so far. (Current weight 17st5.) I understand you usually lose more at the beginning so I'm not expecting that every week! I'll be happy with 1.5lbs a week on average. I have a family wedding in August followed by a holiday so I'm hoping to have lost a stone or more by then and to feel a bit more confident and comfortable in my wedding outfit and swimsuit etc.
My blood test results show that I have high cholesterol, which was not a surprise and is extra motivation to keep up with the healthy eating and weight loss. The nurse advised me to book another blood test in 6 months so that's another mini goal and I'm hoping to have reduced my bad cholesterol by then.
Life is busy, I have two young kids, we ate out for Father's Day and we're going to a theme park this weekend, but I'm feeling able to make reasonably sensible choices and not feel as if the whole plan is out the window if I end up having a small dessert or one or two less healthy meals.
