Don't know where you are from, but for me it doesn't seem stupid asking about losing weight in forums. Asking it from doctor seems more stupid, 'cos I think you can get much more help from internet (from right forums), than from normal doctor... But you're right, this really isn't the right forum to ask about that subject.
Anyway we can try to help OP if he would give some more information about him/herself...
Asking questions about health or anything like that on internet
is stupid.
If you want to buy a gun, you won't go to KFC, do you?
Doctors are paid, trained, and experienced about those matters. And they know the people they are looking for.
