In 2019, a young Bayonne Walgreen pharmacist told me that for the regular healthy adult, there’s a limit to how much one can safely cut starch intake. He said if you cut below that limit, your body will not get enough energy, leading to hunger.

My practical target is 0 to 500 calories of starch. I don’t aim at zero, but if you can “stay at zero” then it’s probably safe. In my experience, it is really tough [1] but actually possible to reduce starch to zero on a long-term basis.

[1] It’s tough because I avoid fat and need alternatives to replace my traditional main source of energy. Protein is promoted as the best source of energy but I doubt it.
