I just started doing IF (20 hour fast with 4 hour eating window). I just had a pint of 2% milk, a tuna sandwich on ciabatta, a cup of oatmeal, and a bag of Erin's Natural Popcorn, and a Columbia Gorge Sueperfoods smoothie. That's around 1200 calories. I ate all of that over the past hour and a half and I feel like my stomach is going to rupture. I've never felt so uncomfortably full in my life. Anybody else have this experience while starting IF?

First couple days I had the same problem. Not anymore... I can eat 3,308 calories in about 3 hours. It is even easier after resistance training. What is the benefit to it over a normal diet routine? A lot, go read about it if you're curious and want to understand it.
20/4 eating schedule IMO is extreme but few people talk about how it addresses one subject that no other diet touches and that is the 'fight or flight' mode vs the 'rest and digest' mode. Digestion takes a lot of energy, this is why a lot of people get tired after huge meals. The body supposedly pulls blood from other areas of the body and focuses it to the digestive tract. During the day your sympathetic nervous system which is responsible for 'fight or flight' is most active. At night, your parasymphetic nervous system is mostly active. Think of it as yin and yang.

If IF is really that uncomfortable for you, there's no need to do it. The only real benefits are satiety and for some people energy levels/performance, so if it's not giving you those benefits - and in fact is doing the opposite to you - then following it makes no sense at all. Alternatively, if you're really set on IF, you could extend your eating window.

yes
Magical? Of course not man...
I have some studies that I've gone through, and many more saved that I haven't gone through yet. Benefits might included but not limited to the following.

Stop trying to advocate something with the wrong support. IF is a different approach for people to deal with there will power vs hunger struggle. You get tired from eating a huge meal because of insulin shock, thats it.
Don't matter anything about parasympathetic ffs.. Calories are calories no matter the time or amount taken in at one shot.****s

While I agree with you that insulin can be the cause, you also can find the same result with ingesting high-fat. Fat doesn't promote insulin release, yet a high-fat meal can yield the same result.
"Paul Li, lecturer of cognitive science at the University of California, Berkeley, offers an explanation: Falling asleep at your desk after that heaping bowl of pasta? You may be experiencing what people commonly refer to as a “food coma.” Medically known as postprandial somnolence, a food coma isn’t an actual coma but rather a lack of mental energy that people often experience after eating a large meal. Symptoms include drowsiness, lethargy and a lack of motivation. But not to worry—this postmeal phenomenon is harmless and can strike anyone who pigs out on foods loaded with carbohydrates, fats or sugars.
What is the link between eating a big meal and feeling sleepy? The process begins as food hits the stomach and small intestine. Eating stimulates activity in the parasympathetic nervous system, which tells your body to slow down and digest. The more food you consume, the more the parasympathetic nervous system revs up, causing your body to focus the bulk of its energy on digestion."
"The two organs in your body that require the most energy to work properly are the brain and the intestines. When you eat, your brain diverts energy towards digestion, sending a bunch of red blood cells over to help break down the food and carry the nutrients all over your body! Because so many blood cells are helping out the intestines, the rest of your body takes this time to slow down and relax. As a result, you might feel tired, since your brain doesn't have as many blood cells to help it out at the moment more energy used for digesting food means less energy can be used for running around!"
I'm just going by what I have read man.
