> The brain runs almost entirely on beta-hydroxybuterate

This is not true.

Quote: The mammalian brain depends upon glucose as its main source of energy, and tight regulation of glucose metabolism is critical for brain physiology.

https://www.ncbi.nlm.nih.gov/pubmed/27826689

Quote: β-Hydroxybutyrate (βOHB), a ketone body, is oxidised as a brain fuel. Although its contribution to energy metabolism in the healthy brain is minimal, it is an interesting metabolite which is not only oxidised but also has other direct and collateral effects which make it a molecule of interest for therapeutic purposes.

> The most efficient diet for humans is one high in fat, moderate in protein, low in carbs;

This is not true.

Scientifically proven best diet: Whole food plant based high carb, low-moderate fat and low protein.

Unless the body is starving, fat and protein are not converted to glucose (the main energy source for cells) to cover energy needs.

Wow the sugar industry is still at it. Read the abstract. The study concludes that mice are incapable of auto-regulating caloric intake because fat stimulates their pleasure pathways causing them to overeat. Kinda like how sugar behaves in humans. See the graphical abstract[0] for a pictorial depiction the authors have helpfully provided.

You are right to question this study and the conclusion of the article. Still, the study shows some important points:

- Professor John Speakman, who led the study, said: “The result of this enormous study was unequivocal – the only thing that made the mice get fat was eating more fat in their diets.

- “Carbohydrates including up to 30% of calories coming from sugar had no effect. Combining sugar with fat had no more impact than fat alone. There was no evidence that low protein (down to 5%) stimulated greater intake, suggesting there is no protein target. These effects of dietary fat seemed to be because uniquely fat in the diet stimulated the reward centres in the brain, stimulating greater intake.

Anyway, one has to wonder why the body has a natural tendency to eat carbs (only in plants like healthy fiber) if they are not part of the natural diet: Sweet fruits. Sweet vegetables. Sugar. Starch products. Processed meat with vegetable spices and not just bloody pure meat like carnivores with the appropriate digestive system.

The Science of Cheese Addiction (2017-03-25) https://www.youtube.com/watch?v=1hE6lhQu7k4

You're wrong about most things but it's definitely cool to see cheese addiction come up in mainstream media. I used to eat whole blocks of the stuff at a time and when I quit I was literally shivering. That stuff might be alright in small doses if you have an eating disorder and need to make food more palatable, but it is not good for adults.

[Robotbeat]

As a Midwesterner, I feel attacked.

EDIT: in all seriousness, I appreciate your anecdote. This thread is convincing me of how little I know.

[rorykoehler]

Don't believe everything you read, even rehashed science journals. You only have to look at what pro cyclists eat to know that fat isn't a cause of weight gain. When I stopped sugar and carbs (but still ate fruit so no ketosis) and started eating high amounts of fat the weight dropped off of me. I was already normal weight (185cm @ 85kg) and I lost 10kg. Fat has absolutely no blame in weight gain.

[JoeAltmaier]

...for some people anyway.

[rorykoehler]

Fat keeps you satiated for much longer and also helps avoid the sugar spikes that accompany carbs.

[ZeroFries]

Protein and carbs are both more satiating. High-fat diet doesn't necessarily improve blood sugar regulation, since insulin resistance can increase.

[rorykoehler]

The study you linked talks about saturated fats.

>A diet very high in fat and saturated fat adversely affects insulin sensitivity and thereby might contribute to the development of type 2 diabetes.

It's well established that sugars are responsible for type 2 diabetes.

>Isoenergetic 1000 kJ (240 kcal) servings of 38 foods separated into six food categories (fruits, bakery products, snack foods, carbohydrate-rich foods, protein-rich foods, breakfast cereals)

This is a badly designed study. It doesn't test the macro level satiety. It says "fat content" which I am going to presume is in the snack foods which are also high in semi-complex sugars.

The thing with all of these studies is that they are easy to try at home on yourself. It's well documented that the sugar industry paid to give fat a bad name but if you eat a high fat, plentiful protein and low carb diet for a month you will now the truth. You can feel it, you can see it.

[ZeroFries]

> The study you linked talks about saturated fats.

True, saturated fat is probably the worst on this front, and unsaturated fat, if it comes packaged with things like vitamin e (to help prevent oxidation) might not be so bad.

> It's well established that sugars are responsible for type 2 diabetes.

No, it's actually not. This is a popular theory, but it's not very well supported. In terms of NAFLD, a strong contributer to insulin resistance, the worst offenders (in the context of a hyper-caloric diet ) are saturated fat and sugar (at 33% of the effect of sat. fat). Sugar only becomes bad when it's converted to fat, which only happens to a significant degree in hyper-caloric diets, when the liver can't dispose of the glucose quickly enough.

Your anecdotal evidence is nice and all, and may work for you, but is no substitute for meta-analysis of controlled studies.
