🚨The #SPC debate is HERE
YouTube: youtu.be
Podcast: peak-human.com
In this 🧵 I want to highlight of 5 arguments, which I’ll call the:
1. validity problem
2. tire and wheel paradigm
3. value add proposition
4. potential to harm
5. not about the carbs
(1) Validity Problem
Satiety is a good abstraction. But when we translate abstractions into concrete paradigms we must acknowledge the gap bw the two
We came to quick consensus that SPC tool is not validated and part of its components and weighting are "completely made up"
(2) Tire and wheel
The argument has been pose several times that the components of SPC are directionally, correct, ie %protein and fiber positively associate with satiety. Therefore, it’s claimed, their combination should be valid a Satiety calculator.  To explain why that’s…

(4) Potential to harm.
If you want to know why I’ve been so animated on this topic of late, here is why: DD served an enormous patient population with whom they’ve built trust over the years. In rolling out an unvalidated and non-scientific tool to “test and iterate” on this…
(5) Not about the carbs.

I encourage you to listen to the whole podcast all the way through (~0:40-1:20 is the main emphasis). Leave you thoughts and questions & hope you are entertained and intellectually provoked
Thanks 🙏🏻
PS - Pulled some SPC values from current patient-facing scoring system,…
