In this solo episode of Vegan Boss Radio, I dive into the narratives of ex-vegans who’ve become outspoken anti-vegans. While I won’t name names, I break down some of the common claims they’re making, why the science doesn’t support them, and how misinformation about plant-based diets continues to spread online.
We’ll look at:
-
The recurring myths about plant based nutrition
-
Why their symptoms likely weren’t caused by a balanced vegan diet
-
How extreme or overly restrictive versions of veganism often lead to burnout
I wrap up with an important reminder: if you're unsure whether you're meeting your nutrient needs, or you're dealing with any lingering health issues, it's essential to work with a qualified plant-based health professional. Don’t let misinformation derail your progress.
