In this solo episode, I unpack the controversial new KETO-CTA study and why its conclusions about cholesterol, ApoB, and ketogenic diets aren’t as clear as they seem.
We break down what the study really found, how it was communicated, and what it means if you (or someone you care about) is following a high-fat, low-carb diet with elevated LDL-C.
With expert commentary from Dr. Alan Flanagan, we explore:
- Who Lean Mass Hyper-Responders (LMHRs) are
- Why the study isn’t actually a “trial”
- The missing data on plaque progression and what was left out
- What non-calcified plaque volume (NCPV) tells us
- Whether this study really challenges ApoB’s role in heart disease
- Why communication matters and how headlines can mislead
- What this means for keto diets, cardiovascular risk, and informed decisions
If you found this valuable, please share it or leave a review. Every share helps the truth cut through the noise.
