Any AME that sends a bunch of his customers to get 'screened' for this needs to be put out of business. If you've read anything from Dr Tilton, you'll see that they're expecting ~90% of pilots to have sleep apnea. And that includes the pilots that look like they've just been liberated from Auschwitz. So just because you're skinny doesn't mean that you won't eventually be a target of this silliness.

'Specialists' such as the OP will likely find 100% of 'fatties' have OSA. The FAA's going to take that information and continue to tighten the standards until 'specialists' like the OP have lined their pockets with every pilot's money. Because they're going to find that every single pilot has OSA, based on their screening criteria.
