You could start your 6 month doctor supervised diet now, so you are that much ahead once you find a new job. Magee has information sessions which are free to attend. You fill out a form and the doctor looks at it later to see if you are a candidate. At the info session, they give you the forms for the 6 month diet for your doctor to fill out (or you can go to Magee for lifestyle classes). If you don’t have insurance now, it’s only $20 a month for lifestyle classes and they fill out the diet form there.
As far as finding a job goes; I don’t see why a company wouldn’t hire you unless you aren’t able to do the work. I suppose some companies might be trying to maintain a certain image though, but that depends on your line of work I guess.
