You're claiming that a human can viably survive their whole life by consuming a daily diet of:
1. Olive Oil
2. Multi-Vitimin
3. Water

My point was that the type of food your calories consist of does matter. If you do nothing but drink olive oil and multivitamins, you will lose a lot of weight and eventually starve to death, no matter how many calories you consume. The point is that the type of food you eat does matter to weight gain/loss (not only the calorie count), because the type of food affects how many of those calories you actually retain.
As far as I can see, this study provides no evidence (nor attempts to) that a diet consisting of nothing but olive oil can sustain your weight. I think it's quite well accepted that different kinds of food will be retained to differing degrees in your body (or put another way, different types of food will end up being passed through your system in differing percentages -- as well as with differing degrees of nutritional satisfaction per calorie ingested).
The oddest thing about reading the comments here is that people are dismissing the words of someone who has spent the better part of a decade in formal education in medicine, and a large part of his professional career focusing on weight management.
I'm not sure how you think this corroborates your claim that you can sustain your weight by drinking olive oil and water (+ multivitamin). In fact, I don't see anything remotely relevant to this in the study.
> If he were to eat that well calculated amount of olive oil everyday his weight would stay constant.
A source for this is needed. The study you provided, as far as I can see, says nothing of this. You're just assuming it's true, and I don't understand how/why.
As per your other reply to the same link
differing degrees of nutritional satisfaction per calorie ingested
Replying here because I can't reply to where you posted this ^^
Everyone's posting it because you are wrong. A calorie is a calorie. If I eat 500 calories surplus a day, i'll gain ~1 pound a week.
Not if you expel an excess 500 calories per day on the toilet. This is what would happen if you chug a glass of olive oil, for example -- your body won't digest it all, and the vast majority of it will pass straight through.
This is an extreme example, but I make it to demonstrate a point 'calorie couters' always seem to forget: You keep assuming that you retain 100% of the calories you ingest, minus what you burn. This is demonstrably incorrect.
Like, "calorie count is the primary determinant of weight gain, given nearly all typical human eating habits"?
Or "calorie count is the primary determinant of weight gain assuming you don't deliberately bypass your digestive system (likely inflicting discomfort and/or harm on yourself in the process) by consuming diuretics or indigestible food combinations"?
Even in both of those cases, it seems like the general point is still pretty much intact.
Bullshit. A calorie is an incredibly crude metric of energy when it comes to human metabolisms. Our stomachs are not furnaces.
Try eating 500 calories surplus of gasoline or wood.
