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…

there was that one dude who went on a year plus water fast and lost like 300 lbs

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…

How does working out at a high intensity work when in a state of Ketosis? I lift weights and/or do HIIT 5x per week and occasionally add running on top of that. I've always been weary of going low carb or trying a keto diet because I feel like I just won't have the energy to continue my training regimen at its current intensity. The typical advice is to eat your allocated carbs 1-2 hours prior to your workout, however I feel like by not getting the right amount of carbs post-workout I'm basically wasting my time in the gym at best, and at worst asking for an injury due to not being able to recover completely in time for the next workout.

Thoughts?

People confuse it with ketoacidosis, which is very dangerous. Ketosis is benign.

The biggest issue with ketogenic diets is elevated level of cholesterol, which is generally considered harmful, though there are different views on this topic.

I have always had very normal cholesterol numbers. It gives you a better HDL (good chol) to LDL(bad chol, maybe) ratio and is good for lowering triglycerides (definitely bad chol) which is the worst type of cholesterol. Your information is not true and is a common misconception about the diet.

Any specific reading on how to get into ketosis that you would suggest? Something that you find scientifically sound?

The causality of elevated cholesterol and coronary heart disease isn't entirely proven. What we see in studies is mostly correlations. Cholesterol-reducing drugs have been shown to not lower the risks associated with high cholesterol levels, so I do think this is an area where we may not have the complete picture yet.

Dr. Jason Fung has a few interesting figures in his book, citing studies where the consumption of eggs for example decreases risks, kind of fascinating.

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

This[0] is a good starting point. Dietary protein can readily be converted to glucose in the body and either stored as fat or used as energy. [0] https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3636610/

The article says in multiple places that in practice, little of the protein was converted to glucose.

Low carb is generally considered to be under 100g carbs/day. Ketosis requires under 20g carbs/day.

Closer to 50g/day, not 20....but the lower you go the more ketones your body produces.

This is a net/gross carb confusion. Less than 50g including fiber, or 20g excluding fiber.

Noted that the underlying cause for the improvement comes from ketones. This should indicate that intermittent fasting would also show similar results. Low carb diet, keto diet, intermittent fasting, they're all just different ways to switch the fuel source from glucose to ketones.

This also lends support to "bonk training", which is an exercise fad designed to exhaust glycogen stores and then continue working out, just as a distance runner that hits the wall continues beyond to finish the marathon, or a cyclist that bonks keeps pedaling to finish the leg.

I think the point is to get your body to make the glycogen to ketone switch more smoothly, and after the bonk every calorie you burn comes directly from fat stores. For most people, exercising in ketone-mode is absolute misery, you physically can't perform at more than about 80% of what you could do with glycogen, and you can't pass your lactate threshold. So bonk trainers do that. On purpose.

Wouldn't just plain calorie restricting also result in ketosis at night? The way I read the headline is "Not overeating might make you healthier"

Not the author, but I have experience with this. For me it takes about a week of slugishness before my body adjusts. Once I'm adapted, my performance is actually better. This goes for heavy weights, low weight/high rep weights, and cardio.
