Just for what it's worth, there are several Soylent-like meal replacement products that are explicitly formulated for ketogenesis. This could be an aid for a person who wants to try a keto diet without having to research a lot of new recipes.

Biolent has a keto variant: http://biolent.ca/

Keto Chow: https://www.thebairs.net/product-category/ketochow/

Keto Fuel: http://superbodyfuel.com/shop/keto-fuel/

KetoSoy: https://www.ketosoy.com/

PrimalKind is "paleo": http://primalkind.com/

Edit: added Keto Chow, which I forgot on first pass!

I'd really like to see this kind of analysis applied to a larger sample.

If someone were to put together a little app to make this sort of data collection trivial and upload it to a central (preferably cheap) repository, would people be interested in contributing their data in exchange for analysis?

Also, since this is HN, is anyone interested in building something like this? I've got an hour or two a week of spare time to chip in.

Unrelated question, mostly for OP: do you know of any publicly available databases of GI/GL info? It's really important for people with type 1 diabetes (a subject rather dear to my heart), and could also be useful for OpenAPS stuff (https://github.com/openaps).

In my experience KetoSoy is incredibly bland and grainy and KetoChow is much better with varied tastes.

I might have missed it, but doesn't look like ketone levels was one of the factors being measured. You can actually buy ketone pee strips at any drugstore for cheap. Would have been an interesting thing to track, since conventional wisdom says that ketosis is binary, you're in it or your not, and the actual ketone level doesn't affect the weight loss. I'm sure this has been put to the test in some experiments already…

I don't contest that ketone level affects weightloss, but just to be clear, ketone pee strips don't tell you anything about your "ketone levels". They tell you the concentration of ketones expelled in your urine, which varies by a lot of things, like time of day and hydration levels. Precision Xtra test strips will give you a far more precise and accurate measure of ketones in your blood and if you wanted to do anyth…

Hmm I don't think you're right. I'm looking at an old bottle of ketostix brand, and it specifies Acetoacetic Acid, which seems to be some kind of ketone. Or maybe it's another byproduct?

Edit - Also, presumably the other factors like hydration and time of day could be tracked as well used to apply learning

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.

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…

Plus you have to up your electrolytes of sodium, magnesium, and potassium. If you don't you tend to have a foggy head.

A keto checking strip[1] would help to be in the know of whether the body is really doing keto.

1. Its available online

100%. i take pills for the sodium and magnesium (they usually have potassium too but usually not enough). and avocados are a staple when it comes to potassium

What do you mean about insulin?

I am very interested as well and hope there is a response. Since he was working with an MD, my guess is as follows: insulin is the devil. Whereas if you look at the old FDA food pyramid and the new food plate, carbs/sugars/fruits take up a significant percentage of the recommended daily diet. Take fruit for example, prevailing norm would be fruit is healthy (especially in its natural state where it is accompanied by…

Interesting. But I thought there's always some insulin after every meal so it's not something that can be avoided. Maybe you mean insulin spikes are the devil?

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 start to eat carbs, see their BMR ramp up, are full of energy, and end up running 5-10 miles a day to burn that energy off, and are pumped the rest of the day.

Also, focussing on weight to the exclusion of everything else is really horrible. It's pretty easy to lose 40-50 pounds and end up being much less healthier than you were before if you aren't careful. Having some sense of your V02 max, your strength, endurance, flexibility, etc.. are sometimes as important, if not more important, than what your weight is to +/- 20 pounds.

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.
