Yeah it’s a grey area. If you are one of these guys who really struggles to eat more, it could be a temporary solution for a few weeks whilst you get used to the extra calories. I wouldn’t recommend it long term though.

So if all else fails, yes eat some junk. But you need to always be gradually pushing it in terms of other “cleaner” food sources i.e milk, almonds, cheese whatever goes down easily (and still has nutritional value).
