To egg or not to egg.. that has been one of nutrition's biggest questions over the last 30 years. Today, we discuss the current state of literature regarding blood cholesterol.

Our BS PS is on the somehow even MORE restrictive version of the carnivo...

Zoe and Oxalates 12.02.2024 44:09
Zoe claims it can send you some extensive home tests, and tell you exactly what to eat based on the results of that test. It's expensive, invasive.. so is it worth it or is it BS? Our (extended) BS PS is on oxalates. These compounds have been demonized in the media as "anti-nutrients" found in plants, with some people going so far as to say its a reason to fully eliminate most plant...
Realfoodology and Salt Substitutes 05.02.2024 44:15

The Zone Diet & 75 Hard 08.01.2024 45:25
The zone diet was originally created to reduce inflammation in athletes. Today, it has morphed into... well, not that. Can the zone diet really stop "decreasing wellness" and "improve aging" and other vague and undefinable claims like that, or is it just a bunch of BS? Our BS PS, presented by dietetic intern Ellen Tingey Doyle, is on 75 hard. Is this a challenge you should try,...

Happy New Year and welcome back! Today we discuss a self-proclaimed "human biologist" who has taken over the media scene in the world of bio-hacking.

Gwen Shamblin and the Weigh Down Workshop 06.11.2023 44:20
