What is the logic behind putting butter in your coffee? If your goal is to lose weight, wouldn't not eating that butter still be better than eating it?
The butter in the coffee supplies fat for fuel / energy, suppresses appetite, and does not contribute to weight gain or more specifically an increase in adipose fat tissue.
Simply cutting all calories is futile. Your body needs energy to sustain itself. The point of keto diet is replacing carbs with a significant increase in fat (~70% give or take) as a percentage of calories consumed.
But it is crucial to actually consume a lot of fat, not just try to cut overall calories.
Edit: I get the point that it stops hunger, but my point still stands, and the parent posters still doesn't make a great deal of sense.
The reason you put butter in your coffee instead of a spoonful of say, sugar, is that fat takes a long time to digest and even a fairly small amount of it (a table spoon of butter in your coffee) takes a while to digest. During that time period your hunger sensation is suppressed.
Coffee also promotes weight loss because it speeds up your metabolism. The idea behind buttered coffee is fairly simple. Put enough fat in your coffee so that you don't get hungry and eat a meal and you help extend your natural faste - and your morning coffee helps speed up your metabolism.

There are good reasons for drinking buttered coffee even if you're deliberately trying to avoid weight loss i.e you are following a net neutral or net positive caloric intake diet. When you're fasting your body isn't spending energy digesting food which means less of your body's immediately available resources aren't spent digesting food.
Even if you're getting calories from your coffee it doesn't impact your weight loss because you're still eating less calories than your body needs to maintain the weight.

I guess it might seem specifically OK for people on Keto diets only, but still, it seems worrisome longterm.
This is completely dependent on other factors. Weight loss is dependent on a hell of a lot of things in tandem. It is mathematically strictly better to say, drink only black coffee or sugar-free energy drinks in the morning. Caffeine is an appetite suppressant. The difference is that most people don't have the personal willpower to stick to the fasting without a few calories to help them along.
Weight loss in general is precisely mathematical in pacing and it will absolutely make you lose weight faster if you consume less calories.
You are ignoring an important factor: If you don't have enough calories the body will switch to starvation mode, you'll have low energy, be cold, etc.
The net result is that, unless you are actually starving (which is bad for you), you'll actually lose less weight that way!
This is a myth which has been proved to be absolutely false. You are simply wrong if you are basing any conclusions at all of of this.
I'm perfectly willing to be shown that I'm wrong, but I'll need more than just a sentence from you saying so.
You said "proved" - can you show me the proof?
Probably the best and most researched article on this.
Bullet point 4 here: http://www.leangains.com/2010/10/top-ten-fasting-myths-debun... has an article reference.
Basically, you can certainly go into starvation mode, but not in any reasonable amount of time. Skipping meals or even fasting for a whole day will not cause "starvation mode". Prolonged calorie restriction can affect hormones like Leptin and affect energy expenditure.
Gary Taubes was the person who I learned from the most, many years ago about high fat, low carb diet, and I have been following his advice ever since, to great success.
He has MANY videos on the internet, here is a recent one:

His book "Why we get fat" is also a great, clearly written explanation of all this, and I highly advise you to look into the subject, with an open mind. You may be surprised.
Moral is, diet responsibly and pay for the metabolic panels when dieting.
The other Keto adage is "calories count, but don't count calories". Meaning, if you eat a high fat diet, you naturally will feel full.
I kinda want to try and start again, it definitely had some benefits, as long as I managed to get enough calories and vegetables/nutrients (sorry I'm one of those persons that needs to take care they eat enough).
The big problem, however, is that in the mean time I've greatly reduced the amount of animal products from my diet--for environmental and ethical reasons, not health. And I'm not really sure how to do both.
I would need to spend a lot of money on almonds and other foods that may not seem that expensive until you need to consume them in bulk to replace the cheap, cheap carbs :) Being nearly-vegetarian is very cheap.
And even though I could probably hack the costs (or figure out something clever to do so), I'm not at all sure if it's even possible to live on a healthy keto diet while keeping my environmental impact footprint to a reasonable size that I can consider myself a responsible inhabitant of this planet. I don't think I can bring myself to eat very large amounts of meat again, even if they're organic certifiably happy cows. Tempeh has slightly more proteins anyway :p (also tastier than tofu, which is not a very high bar, I know)
Let me know if you make any headway! /r/veganketo helps.
p.s. I recently found that dumpster diving asian supermarkets I can get infinite supply of still-fresh packaged tofu, that has sure been helping!
