Somebody with a TDEE of 2000 and a MFP calorie goal of 1800 can possibly eat 3000 calories of meat and net their 1800. Cool, huh? Add a very few well-selected veggies for essential nutrients and rock on.
And I'll note that I did not say you could eat double your TDEE. 133%. That's what I said.
The Thermal Effect of Food for protein is more like 20-25%. So for every 1g of protein you eat, above what you are already eating, is about 1 extra calorie burned. It's minimal at best in the grand scheme of things. But you can equally see that increase in TEF even on a moderate to high carb diet.1 -
OP, the only way Keto would help you lose at a faster rate (outside of glycogen depletion) would be if you are full faster and consume less calories. Some feel full with fat, and others (like myself and others in this thread) do not get full off of fat.

What I wonder is is maintainable? How long can you do this. Are there any side effects of long term Ketosis?1

I agree with @psulemon here. In short, there's nothing magical about Keto or low carb for weight loss. Even though many here will claim otherwise.1 -
Ketosis is real of course. It also suits some people and not others.
Losing weight (long term) in a calorie surplus would mean you have to be excreting any excess calories eaten without absorbing them (sounds messy!).
Low carb diets would typically result in a faster initial weight loss (glycogen & water weight) but over time weight loss evens out between different types of diet and is in relation to your calorie deficit.
@sijomial oh it is. I have Crohn's and became very underweight even on Prednisone and eating at around my old maintenance. Malabsorption and the speed of passage is not fun and very very messy0 -

Ketosis is real....as are the side-effects if you maintain a ketotgenic diet long term. By its nature it isn't sustainable long term because of that and so I tend to discourage that approach to weight loss. You should find a way to lose weight that you can naturally transition into maintenance without changing too much or anything with how you have been eating. You want to learn how to maintain through your diet and if you have to completely change your diet at your goal in order to maintain its not going to work out very well.1

I don't think is entirely true. The carnivores I know (eating animal products only) find their digestion better and their waste is less (protein is digested more fully).
It does appear that some in ketosis can eat somewhat more than their TDEE calculator would have predicted, but I don't think it is due to animal protein. Ketosis is not high in protein, and I know of some vegetarian keto'ers.0 -

It is maintainable although few do it for life unless it really is enjoyable. I've been doing it for over a year. In the low carb group we have a few members who have been doing it for a few years, and there are a few out there with a medical background who have been eating keto for some time, like Phinney and Volek. Others tend t cycle into low carb after a while if health issues have been resolved (like Peter Attia).
Long term side effects are often improved cholesterol and triglycerides.... People will develop short term insulin resistance but after a few days at a higher carb level, this disappears. Some develop poor breath (but for some it is due to higher than needed protein intake) and some get stinkier sweat. Fewer cavities?0 -

Ketosis does my taxes and mows my lawn.1 -
If you really want to know about ketosis, I would go read and/or listen to what experts have to say on the topic. Ben Greenfield, Abel James, Mark Sisson, Chris Masterjohn (PHD in nutritional science), and Dave Aspery are fantastic people to start with.
It is real, and many people have had tons of success on it. It is definitely not as simple as eating all the bacon in the world.1 -
