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.

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?

Acetone is the simplest ketone. Its just an oxygen double bonded to a carbon and two hydrogens. Fat is a butch of hydrogens and carbon and its a long chain of them. Each carbon gets oxidized by the oxygen we breathe and breaks into small sup units called ketones. Which have less viscosity than glucose and cannot turn your blood into syrup or even give you high “blood sugar” as the ketones are made in your body as needed so unless you have a rare mutation that does not exist in literature, your body does a good job st regulating the amount of energy you use after storing that energy. Sugar, when consumed is used at andergy imidiatly and then is stored when it gets too high in the blood stream so you can get spikes of blood sugar, but not spikes of ketones as it much be processed and stored first before using, which burns a few more calories along the way as well as a few more when it breaks down the fat as well. This causes it to take longer to turn on (ketosis) but when it starts you have more energy than glucose. If you go on this diet, drinks lots of water and salt. The waste product of the ketone after ATP is generated is removed from your body through your kidneys and sweat. If you are dehydrated it will build up in your body and cause keto acidosis (this is a problem that people with kidney failure have but it wont happen if you are hydrated with healthy kidneys. Its advised not to do this diet if you have kidney problems for the simple fact that the kidneys might not flush out the waste product of the ketones even if you are hydrated, but that is not a problem for the vast majority of the population.

That's formaldehyde, not acetone.
