According to Dr. D'Adamo's Typebase 4 database he says this about apple cider vinegar for Type A:
AVOID: Flocculates serum or precipitates serum proteins.
I can tell you from personal experience that Avoids, while they may seem innocent enough can have exactly the opposite effect you may be looking for.
I have no idea why you are immobile, but you can loose weight with ER4YT. For myself, I've been on it since the 6th of July and never looked back. I have a new doctor, one I found on Dr. D'Adamo's doctor database. The improvements I've made in a relatively short period of time have me totally sold and convinced this is the only way for me to eat. My doctor is fine tuning my diet for me and I'm really pleased with the results. I have a long way to go (100 lbs more) but I know I'm going to enjoy the trip.
I've included the link to the Typebase 4 database. Good luck!
