Jacky, I've heard that too. Some people indeed say ACV is useful when you have problems with digesting raw food, especially when you just started and your stomach doesn't produce enough acid yet to digest all the fibers. The acid in ACV can help then. Another thing that can help in that case is sauerkraut. It seems to make digestion easier, so this could mean that it also makes losing weight easier as it regulates?
Mel, there are enough people who swear by ACV for losing weight (or not gaining) and other ailments, you could probably google that up. They drink like 2 ts of ACV in one glass of water, maybe a couple of times a day. Certainly not every one here is into Doug Graham, we are all just trying to help and give you different information on the topic. Some of us swear by using ACV, but others just don't.
