A similar ( but not cancer) event with my mom. She's lost 30 pounds in a month at a rehab center. She's just lost interest in eating. They are giving her a small shake that's only about 4- 6 Oz and 200 calories a pop. I'll have to get an empty carton so I can advise.

A long time ago, I had a tiny auntie who couldn't gain weight. An old school doctor told her to drink one juice glass (small glass) of red wine one hour before dinner every night. It actually worked, although I have no idea why. She gained 10 pounds in the first month, and never had trouble keeping weight on after trying it.

A personal story...eating raw carrot sticks seems to increase my appetite. Again, no idea.why, but if I eat them before dinner, I seem much hungrier.

I was very sick a few years ago and couldn't really eat.

I was told by the hospital to get some ENSURE it is called to get some weight on and to provide vitamins, etc. It helped and was not bad taste wise. They had chocolate and vanilla flavors and you can buy it at COSTCO, etc. as it comes in cases. You can also find it at CVS pharmacy, Rite-Aid, etc. Check around as it is not cheap.

I had a craving for tapioca of all things. I was eating stacks of it and found out it is a root commonly used in So. America for stomach problems. You might try that too as it is easy to digest. I also had serious cravings for ... vanilla ice cream!

Wish I had better ideas. Its difficult when you are sick and can't get out much and shop around as you are so very exhausted.

He might try some CBD cannabis edibles if you are in a place where you can obtain such items.

I hope he gets better soon! Take care yourself!

Made for those needing to gain or maintain weight. Walmart can get them for you. Comes in several flavors. Has supplements in it too.

My husband drank it. It's very thick, but it does the trick.
You have to order it.
Also try putting chocolate syrup or strawberry syrup in it to add variety

If he can tolerate it, see if you can get a script for it. It's high calorie Ensure.

I've lived on it for over a year. I take it through a feeding tube. It's too rich for me.

Nuts, oils, peanut butter, Nutella, etc. Add them anywhere you can. Mix them in drinks if necessary.

Two tablespoons of neutral salad oil mixed with Ensure will instantly turn a 200 calorie drink into a 400 calorie one.

Take him to a Buffet and let him take a little bit of everything to see what is tolerable.

TKS to this support group for the buffet and idea.

I made power shakes for my husband: powdered whey protein, whole milk, Ensure, raspberries, vanilla ice cream. I got his 12 oz shakes up to about 800 calories and 40 or more grams of protein.

He had a feeding tube for 9 months and when he was taken off that, he had some extra Jevity,which is a food product for the feeding tube. I mixed a 1/2 can of that into shakes and got more calories and less bulk.

I hope things are better for you.

He fought hard, but in the end, it wasn't enough. He had wonderful in home hospice care and the kids got to spend some time with him before the end. He was aware until the last couple of days so he knew they were there for him.

Although we couldn't make marriage work, he was a decent man and I'm glad his suffering is over.

My husband passed away in Jan. It isn't easy to say good bye.

Nuts, if tolerated can be a good source of calories. 1/3 cup of Pecans have 220 calories.

two tablespoons of peanut butter contains 188 calories
