I am struggling with the same thing. I am around 100 and want to be at 115.
I eat every 2-3 hours and stop eating at 7 pm just popsicles and water after that to avoid issues at night. I have tried eating tons of fat and protein
Like burgers and chicken salmon. I eat 2 eggs every morning on either a bagel or enriched bread with Mayo and cheese. I then will have cottage cheese 2-3 hours later and chicken breast. I just keeping eating all day long like that. I have tried ice cream and shakes, I drink protein drinks but probably not enough because they taste terrible to me and I’ve tried all different ones. I eat protein bars. I am trying to find that right combination of drinking liquids so I am not thirsty all the time( I am not diabetic) I just can’t drink with any food or it causes gas and stomach issues. I have to stick with small meals which I am just starting to do a better job at. I take my one 24000 creon with a 12000 creon amd that amount seems to be good for bigger meals . I take one 12000 with snacks. I had normal looking stools for this first time this week still a bit light colored lol so not perfect. I think I was eating tooo much fat. So thinking I stick to high protein lots of small meals take my creon and I also take Imodium AD or it just goes right out the other end. I am taking lots of vitamins multi vitamin iron and b 12 and glucosamine and turmeric
But eating the bigger meals I’ve discovered is huge for me causes lots of issues

Thank you for your hug!!! A lovely surprise!
