Gaining

Nightly heavy cream shakes

It might be best to ease into drinking that much fat and calories. Your digestive tract needs time to adjust to it. Or you could end up with all sorts of digestive issues. Straight oil not only taste horrid and has horrid mouth feel, but it's likely it will pass right thru you. Personally I've found heavy cream alone to be perfect to add hella calories while tasting good. Some don't like the taste and texture, but I find I like it lol. Also, your body can only digest so many calories at any given time too. I think 1000 calories is the cut off for heavy cream every 4 or so hours. So having about 1000 calories worth after each meal and before bed would be a great balance. Granted, I'm no doctor or nutritionist. Just from personal experience and what I've read here of other people's experience. Best of luck and happy gaining!

Nightly heavy cream shakes

Just be careful and don't overdo the oil/heavy cream. High triglycerides in the blood can cause a bevy of health issues. Also, too much fat can have a laxative effect.

If you go too hard for too long, you may not absorb things properly. This includes nutrients and medications.
