I started my new healthy diet and exercise regime after the May half term. I weighed in at a rather whopping 105kg and I'm only 5'3" tall. This is a BMI of between 40 and 41.
15 weeks on, I now weigh 80kg which means I've lost 25kg. My BMI is just over 30 so I'm nearly out of the 'obese' category. 
I have a very old (1989) Rosemary Conley book and have been using her diet from that. I've been swimming every day for 15 weeks (except on the day of my DD's 3rd birthday party) and now swim 3/4-1mile every day.
I saw my GP last week and she has set a target of 60kg. I last weighed that in 1999.
I'm losing the will to carry on. The change in the weather has me craving cheese and butter. I need a kick up the bum to keep going.
I've worked out that I've been losing approximately 1.5kg a week so it should be just about possible to reach my target by Christmas but not if I start munching on the huge block of cheese that's sitting in my fridge
