Gaining

Milkshakeandfries:
A carton is only like $3

Bigger Cheese:
$3 every day, that might be a bit much long term. Especially since I use heavy cream for other things.

Milkshakeandfries:
Nothing will get you extra calories without costing some money. This is by far the most cost efficient source of calories. If you're not interested in drinking it, that's fine, but if it's too expensive than anything suggested here is going to be too expensive. Calories come from food. Food costs money. Cream is $3. You can get 1200-1400 calories of cream or about 800-900 calories in value menu fast food for about the same price. You don't have to drink a carton a day, have 4 cartons a week for 3 weeks, that should make you gain a couple pounds and cost $36. That's the price of getting Five Guys twice. Are you actually trying to get advice on packing in more calories?

Munchies:
Hun, this not helpful advise. I am glad that you are fiscally secure, but not everyone is. You need to meet people where they are. There is no reason to shame OP.

Milkshakeandfries:
I'm not fiscally secure! I'm extremely poor. That's part of why I chose to try using cream to gain. It's much, much cheaper than any other option I could figure out to increase calories.

Milkshakeandfries:
Anything you do to get more calories in will cost money, cream is the cheapest option for the most calories by far. I don't understand how anything I've said could be construed as unhelpful

Munchies:
I want to be clear. I have no issues with you recommending heavy cream to OP. Even better if it works for you. My one and only issue is that you stated that since OP was worried about the cost, they weren't actually interested in seeking advice on gaining.

Milkshakeandfries:
I kind of assumed that anyone asking advice about how to consume more calories understood that consuming more calories is going to be more expensive than consuming less calories. Also when I was a member of the site years ago, it seemed full of people who just wanted to talk about it, not actually do it, so I'm just trying to understand why if someone is earnestly seeking advice, they'd flatly reject the most economical as being too expensive. My apologies.
