Ruth Is Misdiagnosed With A Food Allergy, Turns Out It’s Keto Rash

[In perhaps one of the most pleasantly detailed e-mail exchanges I’ve had with a reader of this blog, Ruth shares her experience with the Keto Rash and how it was initially misdiagnosed as a food allergy when she saw a doctor.

The rash popped up for her after she began eating a low carb version of the Whole 30 program which is a diet I was also following at the time (If you’d like to know more about the Whole 30, I wrote a summary of the diet here).Read More

Melanie’s Keto Rash Experience

Published in the Dermatology Online Journal December 2011
