Attempting to gain weight

I have no idea about specific groups for people trying to gain weight, but here’s some advice I was given by my son’s dietitian when he used to have trouble gaining weight. He’s a teenager now and eats non stop, so it’s not an issue at the moment. His dietitian told me to add calories to his meals by adding a tablespoon of olive oil or butter to his meals, depending on what we were having. An extra tablespoon of butter in his serve of mashed potato. A tablespoon of oil mixed through his pasta then add whatever sauce we were having. A tablespoon as butter in the pan when making his scrambled eggs. A tablespoon of butter per slice of bread/toast. At the time he hadn’t long transitioned from being fully tube fed to a fully oral diet, so he had a lot of milk drinks at every meal. So for every cup of full cream milk I added 2 tablespoons of full cream milk powder plus whatever flavouring he wanted - sustagen, milo, toppings for ice cream. Sometimes I also added a couple of scoops of ice cream for even more calories.

When he was fully tube fed as a baby/toddler, the dietitian told me to add polyjoule (I think that’s the spelling) to his formula to increase the calories he got at each feed. I added what the dietitian told me to add, but I’m pretty sure it said on the tin that it could be added to food as well as drinks. You get it at the chemist and used to to be in the aisle with the sustagen and other protein powders. I don’t think it had a flavour to it, so it shouldn’t alter the taste of what you add it to. It adds calories without increasing your portion size.
