Quick way is wieght gain shakes. Amazon has a couple brands that are 10,000 Cal per serving. Just drink one of those a half hour before bed. It will turn into pure soft blubbery fat. It will also increase your hunger during the day. After a month make the shakes with ice cream to increase the cal. I used this method to put 40 lbs on a woman last year. Only took a lil over a month. Not everyone will gain that fast though. Good luck
Could you link to a couple examples? I have yet to come across any quite like that.
Just some that claim 1,200, 1,250, 2,000, or even 2,500 calories a serving, which sounds like a lot until you realize just how BIG those servings are.
Seems like cream mixed with some kind of flavoring (like Torani syrups) may be the best for something drinkable that's calorie dense. Add half and half as needed if the cream seems too thick.
Some folks are able eventually upgrade to just cream, which is pretty much the densest liquid dairy fat there is that you can still drink.
