So many things wrong with Bach's statements and many flaws in the study result in gross misinformation. Testing keto response in a crossover study is automatically flawed if subjects aren't given the time to be fully fat adapted. Anything less than 4 to 6 weeks is inadequate and prone to skewed information. And . . . there's the nagging thing about what constitutes low carb. Sad that many who aren't able to perform a critical review will report on this touting the distortions as fact.
