I already saw that movie way back in like 2015. Juicing is not an ideal way of life, but for many people who do it, the do it as a temporary measure for a few months and go back to the lifestyle they had, or they become more animal-based after realizing that raw plant dietary ways of eating are not offering complete nutrition and even damaging their health.
I didn't say fruit is bad, I literally wrote out a whole-ass mini essay on WHO fruit is FOR, and who it is NOT for.
You are correct that everyone is different, but the bottom line is not every adult is at the same baseline. I cannot eat fruit, and neither can many people (again, it's only about 11% of the population are metabolically healthy and have the ability to tolerate it).
I only talk about things I am knowledgeable about and have experience with. This topic (diabetes, nutrition) is literally something I do as if it were my job, even though I do it for free.
