What's interesting about this post isn't the actual diet advice, but the guidance to track and see what works for you. Different people react to fasting differently - some continue to burn calories and drop weight, some just go into starvation mode, have their BMR crash through the floor, and end up exhausted all the time because their body is fighting like crazy to conserve energy. Likewise - some people, when they…

>Everybody is somewhat different in how they'll react to various diet and exercise regimes. Understanding that, and taking a bit of time to watch how your body responds, is the important insight here. This exactly. I did the same thing to lose a bit of extra weight, except the machine learning part was just using my noodle. I found it interesting that the author didn't notice sleep reducing weight right away. He only…

"Bulletproof Coffee"(TM) is snake oil stuff. It's based on the assumption that all other coffee on the market has mycotoxins, yet literally none of the brands in first world countries have them anyway. This was confirmed by tests.

The mycotoxins stuff is yet to be determined, but from what I seen so far there doesn't seem to be a lot of truth in that part.

The ketosis and positive effects on the brain thereof is backed by a lot of solid science.

As a counter point, I did keto for several months last year and found that my concentration and mental clarity were significantly worse while on the diet. My mind operated at about the capacity as it would have, had I slept only 5 hours the night before.

Did you measure ketone levels in any way?

Your symptoms is very common during the ketosis adaptation phase which shouldn't last more than two weeks at most.

If they persist any longer than that you are probably not in ketosis.

The best way to measure ketone levels are through blood ketones (beta-hydroxybutyrate) with a blood tester such as the precision extra or similar.

There are some breath analyzers such as the ketonix that measures acetone levels in your breath - and they are alos pretty good.

Urine sticks don't generally don't work very well after the first month.

Most people find that their alertness and focus improve significantly on keto. The trick is that a) it takes quite a while for your body to get adjusted to ketosis. 6 months to fully adjust, but the primary adjustment will take at 2-4 weeks for most people b) during this adjustment period, you'll usually feel like shit. since you're running empty on the fuel your body is used to. but many people cheat, or accidentall…

I wonder if anybody on Ketosis has ever done an endurance event and not ended up feeling absolutely miserable/exhausted. I was on a fairly low carb regime ( The research that I've read says that the ideal training regime is to work-out in a carb-exhausted state, so as to encourage your body to develop the low-carb metabolic pathway, but for actual endurance events, definitely carb load as your primary fuel.

50 stories? Or 50 steps? Because 50 stories sounds like a lot, not something you should be able to do without a lot of endurance training beforehand. At my best I could climb maybe 15 stories without running out of breath.

Why not both?

Two possible ways: Being underweight is dangerous, just as being overweight is dangerous. Instead of heart disease and joint damage, you end up with osteoporosis, anemia, etc. Losing weight without paying attention to nutrient intake and balance can have similar effects, even if you'd be at or above healthy weight losing 50lbs.

Erhm, yeah, good luck losing that amount of weight easily and ending up underweight...

Stop eating carbs and see what happens. It's surprisingly easy to end up underweight when sugar isn't present.

What I was trying to say, perhaps poorly, that is if you were heavy because you were working out a lot, and eating a lot, and then decided to lose weight by reducing the eating/working out, you can end up being skinny/fat/weak. At the very least, doing regular body-weight resistance training (pushups, situps, pullups, air-squats), helps to reduce the amount of muscle you are losing while you are losing weight.

>doing regular body-weight resistance training (pushups, situps, pullups, air-squats), helps to reduce the amount of muscle you are losing while you are losing weight Can you explain why archaeologists, astronomers and professors have the highest life expectancy and athletes and body builders have that among the lowest?

Do you have a link to data saying that is the case? I've always figured that would be the case, but I have never seen a study/meta-study about it. A quick Google didn't yield much either.

There are also dozens of studies showing exactly the opposite (I've googled up just two): http://www.nejm.org/doi/full/10.1056/NEJMoa022207 , http://www.nejm.org/doi/full/10.1056/NEJMoa022637 . It's pretty safe to assume that currently science is not overly conclusive about this subject. From the point of biochemistry that claim doesn't make much sense either, as calories measured in the food (which is done by measur…

See, studies like these are the problem. They aren't calorie matched making them fully, completely invalid for debunking the point I'm trying to make. The first study says "[the low carb diet] involves limiting carbohydrate intake without restricting consumption of fat and protein", which means calories aren't controlled for at all. Only carbs are counted. The second study has the same problem, read the methodology s…

The other problem is they do it wrong.

One of the ones he linked limited to 20g per day, which is OK, but then increased the amount gradually to be "manageable." Uh, that's not true keto, that's Atkins half-assed keto, which is the exact book they used.

The other one limited to 30g a day, which people over at /r/keto would consider too high, as would most low-carb dieters.

Additionally, they both encourage (or, at best, don't prohibit) consumption of things which can be eaten in small amounts but still have a high GI, such as fruits and other things. It's not just about keeping the carb count below a certain number, it's about avoiding sources of glucose spikes as much as possible, too. They ignored that, and even flew in its face, which, in my opinion, invalidates the testing methodology.

You say much more about youself and you're implicit excuse-system why you are overweight, than any kind of factual information. Been there, lost weight, normal now. The brain is the biggest hurdle.
