After my husband had his stroke he had times when he just did not seem interested in eating even though he had no trouble swallowing. I later found out that at times he was biting his tongue or cheek so chewed more slowly making it more difficult to eat "tougher" foods like steak vs hamburger. I also discovered that, at least for a time, his sense of taste was apparently not what it had been (even today he tastes some foods differently than he did before or than the rest of us do). If I made sure to have a colorful plate of food (not all foods in the same color category say all orange or yellow) he could more easily see they were different foods and it seemed his brain then worked to identify the foods properly rather than blending the tastes together. We never used the food supplements--I didn't think of that at the time since we normally eat more natural. I did find it has been even more important for me to spend a little extra and purchase fresh fruits and veggies as the taste is much stronger without the extra processing. We also grow a lot of our own produce and I put up the extra for the winter months. He is 5'8" and lost about 10-12 lbs before stabilizing at around 150-155 so I think God led me to the right solution for him. It is frustrating when the loved one cannot seemingly tell you what has changed from their side, but patiently loving them and not giving up on finding something that works for them will help you get to a point--a new "normal"--where they and you can thrive even if differently than you did prior to this life changing event. My prayers are for your success.
