My husband still walks, but falls a LOT. He cannot be understood very well. He cannot do for himself, as he has not much use of his hands/arms. He has gone from a little over 200lbs at 6'3" to 145. I can't emphasize enough, the need to get your husband on a high fat diet. It will be contrary to all you've been told about healthy diet, but for pALS it is a life extender. The sooner you fatten him up, the better, because if it gets to the point he has difficulty eating, he WILL lose weight. You may want to visit the ALSTDI website, if you don't already know about it. They are in Boston. Go to the ALSTDI forums and search ketogenic diet.
