Keto Diet Effects on Mental Performance

New / Engb42ba837-

Thinking to try out Keto diet, but I heard it makes your mind foggy. Those who tried Keto, how did it affect your mental performance and job productivity? Also, how did it affect your excercise ability and sexual performance?

    I did keto (intermittent fasting and strict diet) and lost 50 lbs in 6 months. I started slow and skipped breakfast at first then modified my daily staples. I drank apple cider vinegar every morning and had a neurohack regimen including small things like making my bed first thing every morning and brushing my teeth opposite my dominant arm and I believe that neuroplasticity and ketone fuel allowed for me to learn things real fast and focus on getting things done more than before. I’m attributing it to keto (plus neurohacks like brain exercises, supplements (bee pollen, lithium orotate, magnesium, etc), and walking everywhere.

    I also consciously changed the way I walk (chin up, wide strides) and talk (less words, more boom). All of that kept my keto diet and brain function solid.

      Can you talk more about your neurohacks and supplements? Are those suppliments considered nootropics?

      I don’t know enough about nootropics to say but the supplements I used were naturopathic. I always add bee pollen which have chromium, magnesium, and all kinds of other minerals deplete in our modern diet. I also used 5-htp to regulate my mood and sleep. I took lithium orotate in micro doses to stabilize my frantic mind and I was able to focus a little more. I didn’t take it for long though. All this while I transitioned into keto. After a while, I would just be super alert and had control over my mind and mood without any supplements. I simply did keto and exercise to maintain.

      As for neurohacks, they are small but conscious actions that break habits with new ones. It forces the brain to clean up old synaptic threads and create new ones. It makes the brain grow in other words.

      Because as soon as you get sick of it and fall out of ketosis, you get fat again. Nothing replaces proper nutrition and a balanced diet. Keto is for lazy people who want temporary weight loss.

      Falling out of ketosis doesn’t make you fat- being in a constant caloric surplus does. I don’t see anything wrong or “lazy” about people taking advantage of a natural metabolic state that simply causes your body to utilize fat as an energy source as opposed to glucose. The people you are referring to who end up gaining it all back are undoubtably consuming more calories than they are burning on a consistent basis and this would make them fat on any diet- it has nothing to do with Keto. Not being in Keto doesn’t just magically put you in a surplus

      I mean I never said there was anything wrong with it. More so variety is the spice of life, and when you inevitably get bored of being on such a restrictive diet, you may fall back into your old ways (essentially what happens with every fad diet) and start flying blind because you have so many more options available to you when keto isn’t simplifying everything. I’ve watched several friends do this first hand and they’ve all come to me asking how I stay consistently fit, and the answer is very boring: proper balanced nutrition and exercise allows me to eat the foods I love and keeps things interesting.

      Go out for dinner dates, team lunch, brunch with friends and half of the things on the menu will not be "keto-friendly". You will eventually get bored by this and would completely stop the "keto" diet. Plus there are lot of people who lost weight and look amazing now without keto. So eat healthy, exercise and stay happy. Don't fall for such hoax diet.

      Correct. Keto is a scam and probably unhealthy long term. Eat healthy grains, balanced diet, correct # calories, and excersise. Be healthy for life.

      There is so much healthy food that tastes so good. Learn how to use spices, vinegars, citrus, hot peppers, etc. Work less, learn to cook, make time for healthy meals. My healthy meals taste so much better than the quick shit I used to eat. win win

    On keto, you lose everything but energy. It’s like a constant flow since there’s no energy crash because you’re not depending on glucose. Eat healthy fat as much as you can.
    There’s no brain fog but the opposite can be harder to get sleepy. If you notice after eating a big plate of carb you tend to get sleepy.

    - Mental performance and productivity ⬆️
    - Energy levels (besides week 1 on Keto) ⬆️
    - Sleep quality ⬆️
    - Physical exercise intensity ⬆️
    - Sexual performance ⬆️⬆️⬆️🍆
    - Need for post-meal naps ⬇️
    - Sugar cravings and hunger levels ⬇️

    - Breath 😷🤐🤮

    Also, I don’t know where you heard it makes your brain foggy (maybe you are talking about “Keto flu”, which is your body adapting to using your body fat as energy for the first week or so). Most people say quite the opposite long term. What personally makes my brain foggy is a huge insulin spike shortly followed by a blood sugar crash...haven’t had one of those since quitting refined carbs

    The thing I noticed was that I slept less on Keto. Had same amount of energy in the day.

    No. What happens is your body is switching from using carbs for fuel to fat. This shift is when the fogginess will happen and it may last as long as 3-5 depending on your body. Once your switch is complete, you’ll experience the goodness.

    Before that, foggy, tired, sleepy, emotionally messed up, anxious, etc.

    My energy level had improved a lot since Keto. I used to get sleepy and low energy after 12pm, now it’s at night. I feel my emotional state is more stable. But I didn’t lose weight though, which wasn’t my intent from the beginning.

    Why don't we eat just real foods instead of all this shit?

    • Amazon / OtherFroogle
      Could you give some examples of “real food” and what exactly about Keto foods you think makes them “shit”?
      Feb 2
    • Nutanix hcXr87
      Cut down all white food. White Rice, white bread, sugar etc. Eat lot of veggies , moderate fruits , no white sugar. Reduce quantity to 70% of current amount. Do Intermittent fasting sometimes. Switch to more plant based diet. I feel keto is towards one extreme. None of my grand parents did keto. They lived happily till 90+ . Why all of a sudden this shit came up? I don't understand.

      Keto it's an extreme reaction to the horrible sugar and corn laden diet. It's in almost everything so unless you go extreme it's hard to avoid it creeping in. :(

      I was planning to start by fasting for one or two days and then go full Keto. I read it's a good way to start.

      Don’t start by fasting. You’ll collapse. IF works best for keto adapted people when you don’t feel hungry going long time without food and have a metabolism fully adapted to using fat as a source of energy. You need at least a few months of keto to pull that off successfully.
      If you start off by fasting you’re almost guaranteed nonstop headaches and hunger pangs. Keto is not a good short time diet, as beat up as it sounds, it only works if you’re committed to it long term.

    If I interested in starting with keto where can I start. I'm really asking for good references that you read and found out pretty good after churning through tons of bad stuff. I'm primarily a vegetarian (eat eggs 15-20 a week and chicken 1-2x a week) - would it be easy doing keto with that.

  • Ketosis will give you sufficient energy, but your blood sugar is still lower. Your brain depends on blood sugar to perform optimally. So I wouldn’t do this diet if you’re a stock broker, prepping for interviews and studying for an important exam when you need to be extra sharp with mundane details.

      Your brain can run on ketones not just glucose...
      Feb 1
    • Yes I know. That’s not the point. The question is around performance. The brain has adapted to consume keytones out of survival when glucose levels are severely low.

      This does not mean the brain is operating optimally. It will be slower and foggier.

      You can’t be a competitive athlete consuming keytones just like you can’t perform mentally rigorous activities as well on keytones. You can function adequately at best for both but excel at neither. That’s the point.

      Not dissing the diet. I think it’s good to swap out normal diet with keytosis diets from time to time. But there is no free lunch.

      Show me some studies that say using ketones is less efficient than glucose or that fat adapted individuals have foggy cognition.

      I would suggest you look at some research on Alzheimer’s and the usage of glucose/ketones in the brain. As you progress in AD, the brain’s ability to use glucose decreases. However, the ability to leverage ketones does not (in fact the AD’s brain uptakes ketones better than control’s which is interesting. Croteau et al experimental gerontology).

      You of course always require some glucose. Ketones can’t replace glucose entirely (only something like 60% or so iirc?), but my argument is that current evidence shows improved cognition with elevated ketones.
      Feb 2
    • The brain can only run on ketones for 70% of its fuel. Glucose is the main fuel. Your body can produce extra glucose to help the starved brain if you don’t consume enough sugar. But it’s not immediate and instant.

      There’s lots of studies of keto diets for brain injuries and brain diseases. But that’s completely orthogonal to the question of will be able to leetcode better, worse, or the same on a keto diet. We’re talking normal brains here and not damaged brains.

      I’m saying it will be worse. In short focused increments you might not notice any difference. But sustained focus will be impacted. You will lose the ability to stay focused on mundane details. I watched a documentary where they had two identical twin doctors on a high sugar diet vs a fat diet and low sugar diet. When it came to physical endurance and mental endurance trials, the sugar diet won. For the same reason I mentioned in my first paragraph. Your body can function just fine in a normal state. But when your demands are increased, it’s clear you body needs glucose.

      That is why no serious athlete is on the keto diet when it counts and they’re chugging Gatorade, and why stock brokers aren’t on keto diets when they have to strain to focus.

      Just don’t try and interview on a Keto diet. That is all I’m saying. You’ll do just fine with the rest of the stuff.
      Feb 2
    • Google / EngPfjhebs
      Any real studies instead of the iffy twin doctor documentary you mentioned? There are plenty in regards to exogenous ketones, mct oils, etc increasing cognitive performance. I just thought the Alzheimer’s one was interesting.

      I’m not arguing about athletic performance when it comes to high intensity. It’s known that your body utilized glucose better for that.

      Also saying gluconeogensis is not instant/immediate is misleading when you phrase it like that. It’s on demand driven and when your blood glucose starts to lower gluconeogensis ramps up. There isn’t a need for it to be “instant” as your blood glucose doesn’t get lowered instantly.

    • Sure. There are studies into this primary around memory recall. I’ve just read the summary and not the full abstract.

      https://www.webmd.com/diet/news/20081212/no-carb-diets-may-impair-memory

      Naturally these studies measured the effects after the diet is in full swing (a few weeks I think). This is a common effect.

      And since diets like Atkins and other keto diets are not meant to be sustained long term diets and you are intended to start and stop them, you will hit this brain fog period multiple times. There are negative health benefits to sustained high fat low carb diets.

      So I rest my case. Use these appropriately. Don’t use them if you want your brain and body to be functioning on all thrusters. Day to day routine is fine. But studying for the bar exam or prepping for FANG loops...not advised.

      You should’ve read the study more thoroughly. They base most of their results on week 1 where they assume glycogen stores are utilized. If these test subjects aren’t far adapted, it is very likely they will experience the so called brain fog. To also draw that conclusion from the visiospatial map tasks is also dubious in my opinion.

      You can rest your case because it’s clear you never read any actual literature and I’d rather not waste time.

    • Lol. Okay grumpy gills. If it’s so important for you, why don’t you take a victory lap and accept your participant award. I presented my evidence with facts to back up my premise statement. That’s all I’m required to do. This isn’t the academic octagon FFS.
