Drop all starchy carbs and replace with meat, eggs and vegetables. It’s not rocket science.

You need to add some butter, oil and heavy cream, or chances are you are not in ketosis: 80% of you calories intake should come from fat to guarantee ketosis.

Pecans and other high-fat nuts are great for snacking, too.

The title is terrible, it should read ketosis/ketones may prevent, reverse age-related effects within the brain. "Low carb" as the title currently reads does not necessarily result in ketosis and your body/brain running on ketones, which appears to be the scope of this study. There is more to dietary ketosis than low carb, just as an example carnivore or paleo diets are low carb, but those will generally not result i…

I always thought it wasn't recommended to stay in ketosis for more than 2 weeks at a time?

I cannot say that it isn't recommended, because recommendations are quite diverse. But I haven't seen that recommendation before.

Orthodox nutritionists would definitely advice against ketosis, potentially they may be fine with fasting-induced ketosis every once in a while (depends a bit on how they were trained).

People who embrace a low-carb ketosis-inducing diet (aka "Keto diet") or embrace multi-day fasting don't consider it harmful really. For fasting there are of course certain limits but not due to ketosis but for other effects of not eating (refeed effect, general weight-considerations, etc. but there have been overweight people successfully fasting for months under supervision).

Sugar, not fat is the killer. Incredible how for decades bad research and the likes of Ancel Keys and Phil Sokolof put the health of millions at risk.

Healthy diets (low carb, moderate fat/protein/fiber) don't generate outsized profits for the agriculture and processed food industry.

This kind of conspiratorial thinking blows my mind. The claim is: big ag, with all their grain production, wants Americans to eat lots of grains, and corrupts government agencies to recommend such diets. The real healthy diets include lots of “protein” (meat), but “they don’t want you to know”...

What’s incredibly absurd about this is: where do you think the vast majority of the farmed grain goes? Feeding the cows, chickens, and pigs providing your “high protein” diets. If these “big ag” businesses did have any sway or disinformation campaigns, they’d absolutely be pushing the “eat more meat” narrative.

There’s no conspiracy. There aren’t any u-turns in nutritional science. The USDA guides are almost completely identical to WHO nutritional guides, and the guides for virtually every other modern country. Lots of whole grains, fruits, vegetables. Limit sugars, salt, and fats. As Michael Pollan says: Eat food. Not too much. Mostly plants. That’s pretty much it. We complicate things so much with fear mongering and conspiracy thinking.

I am having trouble agreeing with the statement that "...your body will convert the protein to glucose..." Could you elaborate on that logic?

While several people refer to gluconeogenesis, to the best of my knowledge we _can_ make glucose from protein, but rarely do in practice. I have yet to see anyone convincingly show that we do.

Also check out diet doctors take on it which refers to actual studies. "Does protein adversely affect blood sugar?" https://www.dietdoctor.com/low-carb/protein

This is a pithy statement belies the complexity of nutrition. Besides, researchers that linked heart disease to dietary fat didn't recommend that sugar be substituted in. And the diet heart hypothesis seems alive and well today; lowering blood cholesterol and saturated fat consumption is what health practitioners still recommend today.

Unless one has too much lean meat. The body will convert excess protien into carbs. It's better to stick with fatty cuts only.

This also depends on eating frequency. If someone has a very low eating frequency, like a single meal every 72 hours, even a meal of lean meat may not knock a person out of ketosis, at least for very long. I've fasted that long and eaten a huge meal of lean meat, multiple times, and my keto testing strips always remain dark purple. As much as I think keto and carnivore are lightyears past the average American's diet,…

I lack the energy to be effective when working out

I found that I cramped, also. Eating 1/2 apple immediately before working out seemed to do the trick.

For my understanding this is mostly attributed to insuline resistance vs sensitivity. As you get older and overexposed to sugar, your resistance raises and in order to reverse a lot of the internal inflammations your body has produced from over-intake of sugar you need to force ketosis and burn calories with a low-carb diet. This in turn helps reduce internal fat and repair organ functions, fundamentally restoring hormone production and refreshing your brain as well.

It does not mean that carbs in general are toxic, nor that this diet is recommended for everybody! Diets are very personal, it just becomes more and more common because sugar is added everywhere, people are getting older and older and obesity is a global problem. As such, most people are very insulin resistant and work better with low-carb/high-fat diets.

This headline is one of the reasons there is so much misinformation in food and diets

I have but in my case it is not caused by continued low carbon diet and should be avoided and is not so nice due all the side effects it has. Everyone who takes any form of diabetic medication should ask their physician about the consequences as it might interfere with the medication or require adjustment and can cause acidosis even if you have normal glucose levels. On the other hand, especially for type 2 diabetics…

Ketoacidosis is of course a medical condition and not something one seeks out.

Ketosis is fundamentally different, your bodies mode of metabolizing (body) fat in the state of fasting, which can also be provoked when eating a high-fat moderate protein and And yes, asking a physician may be a good idea if you suffer under certain conditions. Sometimes it may be valuable to find a physician that has knowledge on keto-diets, because that's not really something every physician learns about as a dietary choice.

“The bad news is that we see the first signs of brain aging much earlier than was previously thought. However, the good news is that we may be able to prevent or reverse these effects with diet, mitigating the impact of encroaching hypometabolism by exchanging glucose for ketones as fuel for neurons.”

The alternation with ketosis as source of energy is key as it seems...

The brain’s response to diet was tested in two ways. The first was holistic, comparing brain network stability after participants had spent one week on a standard (unrestricted) vs. low carb (for example: meat or fish with salad, but no sugar, grains, rice, starchy vegetables) diet. In a standard diet, the primary fuel metabolized is glucose, whereas in a low-carb diet, the primary fuel metabolized is ketones. However, there might have been other differences between diets driving the observed effects. Therefore, to isolate glucose vs. ketones as the crucial difference between the diets, an independent set of participants was scanned before and after drinking a small dose of glucose on one day, and ketones on the other, where the two fuels were individually weight-dosed and calorically matched. The results replicated, showing that the differences between the diets could be attributed to the type of fuel they provide to the brain.

isn't ketosis very subtle to maintain otherwise it can harmful effects ?

No, like other people have said that's ketoacidosis. Both involve some ketones, but one is healthy and natural(ketosis) the other is very bad and you should talk to your doctor about it (or he is most likely the one to find it) that is ketoacidosis.
