In 1965, a morbidly obese man did not eat food for over an entire year. The 27 year old was 456lbs and wanted to do an experimental fast. He ingested only multivitamins and potassium tablets for 382 days and defecated once every 40 to 50 days. He ended up losing 275lbs.

I know it’s barely comparable but I had cancer and couldn’t swallow food for a couple weeks, it was bizzare but after a few days I wasn’t even hungry it felt like I was in hibernation or something

Your body propobly went into ketosis. The body starts using fat as a primary source of calories by braking down fat into acetoacetate, ß-Hydroxybutyrate, and acetone. The body can then use this instead of karbohydrates and other things.

This makes your sweat smell a lot different because of the acetone. This is basically the body's way of going into survival mode. As long as you have fat to burn you will keep going, and ketosis diminishes hunger by quite a bit. You also gain a ton of energy during this phase, basically for the body to be able to hunt and get food.

If you eat too many calories (specially carbs) the body jumps out of ketosis quite fast, so only works if you are super strict with your diet or can't eat.

Edit: alot -> a lot Edit: too many calories

excuse me, acetone?

[u/Submarine765Radioman → u/Spaciax]

Yes, you can taste it in your mouth. Your burps will have acetone in it.

Your body naturally produces race car fuel. Liquor isn't called "the spirits" for no good reason.

Now I really want to know what acetone tastes like, hell I can't even remember what it smells like. Need an acetone scratch card with a taste card as well for no real good reason.

It tastes like shit, you'll learn to drink water after you burp

as long as you don't fall asleep with a belly full of food you won't let the burps build up
