I want to quickly gain ~25 lbs over a few months just for fun, but then lose it. I was thinking the easiest way to do this would be to use heavy cream, but I’m worried about long term effects. If I gain 25 pounds with heavy cream and then lose it, will I be the same as I was before the gain?
You do tend to gain subcutaneous fat with cream, which on average is harder and slower to lose than visceral fat. Any other changes will depend on your genetics, like where your fat accumulates and any changes to your body shape because of it.
How much your body changes will depend on your height too. 25 lbs is going to make a more dramatic change to someone that's 5'6 vs someone that's 6'2.
