Hi Toni,
My doctors surgery was also very unhelpful. The head receptionist kept finding excuses not to give me an appointment, until I nearly missed joining my current group. I had to pay £24 to get the form signed, and she tried to scare me by saying it might cost the same as a full medical (£100+). You must remember that you are not asking your doctor for an endorsement - they might not like Lighterlife but they do not have the right to tell you what you can or can't do. They CAN advise on how a VLCD might impact on any medical condition you have or medication you take, so you need to listen carefully to that advice. I didn't have any medical problems or take medication, but I WAS morbidly obese! My doctor said she was concerned about my keeping the weight off afterwards, which is fair enough. I just wanted the chance to be slim in the first place! Four months & five stone later, I'm truly getting there. Stick to your guns, insist on an appointment, be firm in saying you don't need an endorsement, you just need your doctor to sign the form to show that there's no reason you can't follow the diet.
As I don't have any medical issues or take medication, I get my monthly blood pressure & pulse checkups done at my local Lloyds Chemist, which is free, and a lot more friendly!
I can't wait to see that same (fat) head receptionist again when I've reached my goal.
Good luck,
