One big difference why ex150 worked for me, but not you, and potato vice versa, could be adapting to GI issues.

I had been on lowish-fiber keto for about 7 years when I tried the potato diet, and I didn't peel for the first 1-2 weeks because I was told "all the nutrients are in the skin."

I was barely able to eat more than 600kcal of potatoes a day, and was bloated beyond belief and starving at the same time due to this.

In reverse, ex150 is EXTREMELY ketogenic and relies on pretty strong dairy/fat tolerance. Some people might not do well on that without ramping up slowly, or maybe never in some genetic sense.

GI wise the diet was great actually, probably the best I had. I had zero bloating and good bowel movements. With this potato diet I have minor amounts of gas, but at least it’s not stinky like lactose.

The lactose is also pretty minisucule in cream to not trigger my lactose intolerance, which is a recent development. Also my default diet was pretty low carb and high meat and fat for quite a while, so I’m used to fat a bit more than usual I think.

I also got sick with potato-with-skin too, which made me stop my first potato attempt relatively quickly a few years ago. Once I figured out solanine has a 26hr clear out cycle, I realized I was building up too much with the skin and tried again with peeling with much greater success.

I think that individual variation is actually a key factor why diet advice is not universal, and after my genetic testing I’m not very surprised that carb heavy potato works much better for me. I’m working on a prototype web app to help people figure this out right now actually.

Interesting, what sort of heuristics are you using?

I was going to make it a blog series at first, but then realized making it a survey web app would not be much more work and less time to spend to absorb it for people. I have a lot of detail in my head so its hard to summarize quickly and I’m on my phone but for v0:

- health blocker checklist (hypothyroid, gi, etc)

- previous attempts ( what did you try, how did you feel doing X, etc)

- goals

V1 :

- genetics and bloodwork

Questions will add tags and then recommendations would be calculated based on tag. Kind of based on text adventure games somewhat

Nice, would be interesting! The thing with genetics/blood work/thyroid is, I'm not sure we know anything from those. Unless you actually test hypothyroid, and even then, what does that tell us in terms of diet recs?

It's mostly a 'flight launch checklist'. Or testing if your ethernet cable / power cable is actually working properly before going crazy with more obscure things. Sometimes, you just need something like a new power cable and thinking your power supply or CPU is bad (more obscure things) is a counterproductive rabbit hole.

For example if you have a hypothyroid issue, then I tell you to go fix that vs. focusing your energy on diet first. Then once you get started on fixing your 'obvious' medical issues, then focusing on diet can help. GI and diet is very linked, so I wouldn't tell you to go only fix the GI issues and then try to lose weight, but it might modify the diet there.

Genetics will bring up micro-nutrition issues you might have unique issues with, and many micronutrients are involved in insulin / glucose metabolism. If you end up needing way more of a nutrient, or genetically don't process a form of nutrient that well (ex converting beta-cartotine in plants to retinol (vitamin A), or have a biotinase polymorphism that causes you to not recycle biotin as efficiently, leading to you needing more of it), then that will also change diet considerations.

Like when I did a genefood analysis, they came up with https://www.mygenefood.com/custom-nutrition-plan/villager/ (plus a bunch of other details)

Which is against a lot of low carb orthodoxy, but after seeing my results with the potato diet, it might be true for me? My heart rate goes down, my mental energy is better, I'm loosing weight with less issues than keto with less muscle loss and so on.

Yea I use it similarly, to rule out things. E.g. if your RMR comes back normal, we know you probably don't have a massively down-regulated metabolism.

I'm more skeptical of GI and genetic testing because I get the impression the proponents of those like to read tea leaves, there's often just no there there and they make up all sorts of shit.
