Sadly this is a definate problem with this disease. People believe they have eaten when they haven't and food no longer is as enjoyable as it used to be, very little in life is as the disease progresses.
My husband has not lost weight yet but he is losing his enjoyment of food. He used to love to eat and was so crazy about my cooking he would often take pictures of the meals I'd fixed. Now he rarely knows when he's hungry and forgets what foods he likes and says food just doesn't taste good anymore.
It is real important to keep them eating as much as you can even if it means feeding them things that are not necessairly the best for nutrition.
With my husband he would not drink the shakes, said they tasted like crap and he'd rather starve. I make him fruit smoothies and he likes them well enough to drink them, thinks they are fruit shakes but I use things like fruit juice, fresh or frozen fruit, rice milk, yogert for thickener and honey for sweetness.
Good luck but realize your mom will continue to lose weight, lose interst in food and eventualy forget how to eat. Hugs, Georgia

Hello... I just joined. I have noticed my dad has lost a great deal of weight. I think is due his stuborness, more than forgetting to eat. He and mom are now in a facility, and dad is always complaining about the food. He has become angry with the cook staff, demanding they cook better meals! At first when they moved to the home, he would call us and ask if we would get them some extra food. We did not mind doing that, we were just wondering why they needed so much since they had a dining hall. We began asking questions and found out that they were not going to meals regularly. Dad would go on the outings and pick up snacks for their room, and they would only eat them.
We finally got them to the point they eat the designated meals which are healthier than any snacks. From time to time we carry them a burger as a treat, but not that often.
Mom eats her breakfast but very little lunch or dinner.
