I still don't understand the tech bro fascination with disordered eating.
Given the current state of health in western countries, I would claim the stasus-quo is actually disordered eating.

#182The 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.

Anything that requires me to radically change my diet to experiment with myself "just to see", that takes a minimum of 2-3 months, is a hard pass. It's just not that interesting to most of us for a vaguely hand-wavey possibly useful experiment.
I think that's fine; not everybody has to be an early adopter of everything. If what you're doing is working for you, keep doing it!
But for people who feel vaguely but persistently like things aren't working anymore, I really recommend experimenting with diet. I've tried a variety of things over the years, and have ended up with a combination that has made my life hugely better: better mood, more even-tempered, much more energetic, and physical exercise has gotten a lot more fun. I recently went back to my old diet for a week and felt like warmed-over garbage.
But yes, expect it will take 1-3 months for your body and habits to really adapt. E.g., when I quit refined carbs, I experience 1-3 weeks of withdrawal symptoms. Headaches, low energy, enormously cranky. And it's even longer for the habits to really get established, so I stop feeling like I'm missing out on the old things.

> If you have never entered ketosis and experienced your brain running on ketones, I would suggest you experiment for yourself. I would say a minimum 2-3 months which should be enough time for your microbiome to change and your body/brain to adapt primarily running on ketones. I've been on Keto for about 8 months (before giving up), measuring my blood ketones and being in deep ketosis between meals (over 2 mmol/L). I…
>Also most people are in ketosis before eating breakfast in the morning, because the liver's glycogen is partially depleted overnight This is true...but it gets to my point, just because your body begins breaking down fat and producing ketones (as shown in your tests) does not mean your cells have adapted to using ketones as fuel, that requires the body to adapt. Based on your numbers you were clearly breaking down f…
Yes, everything you're saying is a complete myth. Define what it means for the cells to adapt for "running on ketones".
There's no such thing.
> "I would be surprised to learn you engage in lets say an hour of cardio 4-5 times a week"
I ride my bike or walk to/from work about 10 Km every day and I do weight training 3 times per week, which puts me in the moderately active category.

Afaik there is no top athlete on keto when performing: they are all on high-carb. Keto is the "burn your body fat" mode. Staying in keto by eating high fat low carb is a trick. Humans never had such easy access to fats as today. Before we made settlements we got a large part of our calories from fruits (which contain short carbs), not unlike the other primates.

This can't possibly be true. Agriculture is only 12,000 years old or so, but people have been living in Europe for much longer than that. I'm in North America, and there are no fruits available locally for six months out of the year. Before agriculture people must have been living mostly from hunting.

So anecdote extrapolated to everyone and anyone who disagrees is just imagining it.
Not being hungry until meal time? Placebo effect caused me to not want a nap in the afternoon? Did I imagine the 60 pounds weight loss, too?

> How does working out at a high intensity work when in a state of Ketosis? I've done this. You get tired much faster, you will not be able to sprint for nearly as long, your maximum lift significantly decreases, you hit the muscle fatigue point (can't lift again unless you lower the weight) very quickly. The usual solution among keto lifters is to have a carbload cheat day once per week _or_ to carb spike with I thi…
Agreed. The difference was noticeable and as soon as I started eating carbs again, my strength increased in a matter of day or two.
How long were you in ketosis before you stared eating carbs again?

Is this definite and scientific consensus? Nutrition research seems to change as often as JavaScript framework of the month. I saw one Ted talk that essentially said "everyone is different and no rules apply to everyone".
> Nutrition research seems to change as often as JavaScript framework of the month. Nutrition “science”, like most health-related “sciences”, has approximately zero predictive power. A pretty reasonable strategy is to completely ignore whatever helpful advice the FDA or whomever is currently spouting (food pyramid!) and come up with some plausible first-principles model that matches available anecdata, like trying to…
Agreed. The problem is that doing actual controlled studies is really hard. You have to take a group of people and randomly assign them the diets you want to study, essentially locking them up for the duration. It could possibly be done, if one of our billionaires took an interest in this problem.

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, howeve…
I confess I don't measure ketosis, and it sounds like we do different sorts of workout. But I do the intermittent fasting variant known as eTRF; I generally eat 7 am - 1 pm. I was worried about how that would interact with my runs, which I usually do in the morning before eating. Enough people online were positive about it that I tried it out and it has been great. On recent Sundays I've done 2-hour runs with little or no food. My times improved and I felt amazing. And the meal after running? Fantastic!

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

Can you take vitamins like B complex with electrolytes and sugar free, no carb protein shakes with caffeine to get some energy back?
The problem isn't lack of energy. The problem is muscle and cardio exhaustion. You feel great, not tired, just your muscles stop working and you run out breath. So I don't think that vitamin, electrolytes, or more calories will help. If you're lifting seriously, you're already consuming plenty of those things.
