Dr Caryn Zinn
A Damascus Moment
Zinn says she was “very loyal” to mainstream low-fat, high-carb dietary guidelines.
Schofield came across some old high-fat related research, five years ago, and asked her opinion.
She almost said. “Take your low-carb diet and go somewhere else. I am the dietitian and I know."
Instead, Zinn scrutinised the research. She was soon “flabbergasted” to realise that everything she had learned and thought she knew about diet and nutrition was wrong.
“The evidence that led to mainstream dietary guidelines was largely observational, correlation-based research,” Zinn said. “From a quality viewpoint, it did not compare to the solid, randomised controlled trials (RCTs) that were available to support low-carb, high-fat diets.”
Zinn in her practice worked with many who weren't able to maintain the weight loss. She began to realise that there was good reason: They were constantly hungry because they were eating too many carbohydrates and too little fat.
Part of that realisation involved understanding why carbohydrate really isn't an essential nutrient.
Zinn also realised that fears about low-carbohydrate and ketogenic diets, that worried her, were “just scare mongering”.
As a consequence, Zinn said: “I'm embarrassed to say that I used to teach my students that low-carbohydrate diets were bad because ketosis was bad.”
Zinn and co-author Grant Schofield, wrote a book called “What the Fat: Fat's IN: Sugar's OUT,” 2015
and a new one called “What the Fat: Sports Performance,” 2016
