It can definetly be a challenge living with multiple blood types in the house, but there are recipes that will help alleviate this, it is certainly not the easiest thing in the world though. Spelt bread is much like wheat but it doesn't usually cause the same reaction so most people can tollerate it fine, i would personally recommend that you shoot for ezekiel or another sprouted grain because these are considered "live" gains and are much better for you.

In regards to your weight, the Blood Type Diet really isn't a diet in the conventional sense because it's purpose is not for you to lose weight but to NORMALIZE weight, you should see your body gradually gain weight until it reaches a healthy level, just make sure you are eating enough. You may have some condition that imbalances you and causes you to be underweight but i don't know enough to say what that may be? I would just try the btd for a awhile and see how that goes, there are also certain protocols for aiding in the the recovery from a particular problem, thos can be found on the http://www.dadamo.com
