I don't ever watch television (we have no digital decoding box, the TV is for DVDs) and I can't waste the time to watch this performance on the internet.
There are two truisms I love.
First: How can you tell when a politician is lying? You see their lips move.
Equally good: Any semblance of television documentaries to real life is purely accidental.
For a lesson in how to stack a real study against low carb this Oxford group beats any television entertainment hands down. Also, if you ignore the crap from the researchers, there are lots of interesting (pro LC) data in this study, especially the myocardial energetics and body composition.
What they found, and which made the tittle of the paper, was the gem that LCHF eating "impairs cardiac high-energy phosphate metabolism". Baaaad?
What I really liked was that despite "9% lower cardiac PCr/ATP (P< 0.01)" there was "no change in cardiac function".
Ketones. Ketones allow normal cardiac function at reduced PCr/ATP levels. Ketones (from Veech's work) bypass insulin resistance, be that pathological as in Alzheimers or physiological as in very LCHF eating. Cardiac muscle functions well at reduced ATP levels, provided ketones are available.
Feeling like crap in the early stages of ketosis (Atkins Flu™) is common, it's usually at its absolute worst at about a week in to ketogenic eating. This group clearly knew how to time their cognitive testing! They have more of an agenda than I do.
Both the study and the TV drama have the potential to injure people who need ketogenic eating, I guess the TV show more so than the Oxford study, because it is more likely to stop grass roots level defections from Weight Watchers to genuinely healthy fat-based eating.
