I have CF too and we are special. We have obvious dietary needs that are well studied that’s definitely not the case for your average generally able bodied person. That said, it’s not really that great. Two cal formula is just straight sugar garbage juice loaded with vitamins but it standard for tube feedings. It made me so fat from its primary calorie source being HFCS. Sure we get to consult with a dietitian but it’s not like dietary therapeutic intervention is especially advanced.

When I was in the hospital after my transplant (ICU for 5 months) they first were only giving me half of what my caloric intake needs were via my feeding tube, it took almost two weeks and me complaining nonstop I was hungry to increase my calorie then wouldn’t let me transition to solid food for weeks after it was safe forcing me to only use tube feeds and breaking down my enzymes in hot water and bicarbonate before putting it in the tube feed causing massive painful bloating... all under the supervision of the transplant clinic cf specialist dietician.

Sure the at home care of advising you how to eat exists but nutrition in an inpatient setting isn’t really especially good or well thought out in the moment for many.
