> I am able to reduce my daily meals to 2 by having a bulletproof coffee in the morning.

For whatever it's worth, two tablespoons of butter on your coffee is 204 kcal according to Wolfram Alpha. Even Bulletproof says things like "Bulletproof Coffee is breakfast" and "curbing your hunger with food that keeps you full for hours. Bulletproof Coffee checks those boxes." which I read as saying that they think of it as (liquid) food. https://www.bulletproof.com/recipes/bulletproof-diet-recipes...

You're replacing a potentially less structured breakfast (I eat different breakfasts every day) with a single standardised one. If you buy Bulletproof's analysis, you might be doing something ketogenic which might be beneficial in some way. But you're not skipping a meal. Though there is a blurb on that page that says something like "you're having a meal without breaking your fast because [arbitrary definition we made up on the spot]".

For whatever it's worth, I wouldn't take health advice from a product sold with an origin story of "the founder was dangerously overweight and at acute risk of stroke or heart attack at the age of 30, so the biohacker in them decided it would be smart to go on a difficult mountain trek in Nepal".

True, I don't believe anything that is marketed/advertised as "miraculous". While bullet coffee doesn't give me superpowers, it does however helped me to "replace" (skip is a superstitious word, I agreed with you) breakfasts that would otherwise be full of sugars and such. The hunger disappeared from 6am (when I wake up) until around noon.

I think diet is not just about the food and nutrients but also the lifestyle. You can't expect someone to always be taking meticulous steps in measuring their intake, most will slip away. Start trying out small adjustments to see whether you can make it a habit, else it is not a good idea.

For me, the coffee helps me stay full (physiological or physically) and don't make me grumpy the whole morning, yet still having the energy to crush it.

I am actually looking for more replacements/practices that would allow me to eat just enough and suits my lifestyle, instead of following a specific regime that is coupled with courses that they sell you.
