They probably aren't actually eating this, and it wouldn't work any better than using heavy whipping cream, and would probably be worse, frankly.
Most effective way to gain weight I've found is to drink half a pint of heavy whipping cream 4 times a day after meals. I mix it with chocolate syrup. If you do that for about four or five days and then take a day off and then do it again for four or five days, that should make a noticable difference. Also if you get lots of fattening snacks and, if 420 is legal where you are, use it to give yourself the munchies. Eat dessert after every meal. I gained 50 pounds in about 6 months doing this.
Bombing your stomach with 10000 calories mostly in the form of oil isn't going to actually make you fat. Adding a thousand calories to each of your meals is
That'll do it.
Another way is to just stuff yourself at breakfast and then have a huge snack every two hours or so, between meals, to maintain that stuffedness through the day.
If you don't want to go through the hassle of counting calories.
