Welcome Lorraine.

I'm 4.5 years from my original treatments, plus others, and still recovering. I lost over 110lbs, mostly muscle, in a matter of weeks just from chemo, which was from cachexia aka wasting, which is more than just the lack of nutrition, but is metabolically. Anyway, I gained back 50lbs of the weight I lost. Muscle, fat has memory, and can go back to it's highest highest point more easily than someone else. I found with cancer it's not as quick to regain as before.

I had food aversions for almost a year after chemo. I couldn't eat potatoes, bread and others due to the texture. It took awhile through trial and error to find foods I could tolerate, and then have it change a few months, sometimes for the better.

You're right, fat has taste. There are other fats in healthy oils, butter, foods, which I incorporate often in cooking. Even spraying oil on foods help with swallowing. Last night I made mashed potatoes, and I use a stick of butter, which is the key to make then creamy. Same things with scrambled eggs, like 2 Tbs butter for every egg used, cooked slow, makes them creamy, curd like.

Good luck.
