I don’t know where to post this, so I’m posting it here.
I need to gain some weight because I’m borderline anorexic. But I can’t afford much more than bread, potatoes, eggs and cheese, That is my diet. And I hate eating it. It’s the only thing I can stomach that is cheap, but I hate it. I don’t want to eat eggs and potatoes for the rest of my life. I would rather die of malnutrition, like I am currently doing.
I have no appetite, but that is a symptom of something else. Ideally, there is a way to gain weight while eating less mass. Something calorie dense.
I might be slightly exaggerating. But for the last couple of years I’ve been eating potatoes and eggs for almost every single meal of the day. And yes, I eat one warm meal a day. Sometimes I suppliment with some bread to stop the hunger pains. Sometimes I also eat a piece of vegetable.


On a calories per dollar-ratio, oil is probably at least one quarter of the price of potatoes.
The difference in electricity costs is not going to be significant in the context since you’ll make back the money on the calories you ingest from the oil instead of more potatoes.
Cooking potatoes in oil is also very significantly less miserable than eating boiled potatoes, and this is coming from someone that actually likes boiled potatoes quite a bit
