Your Heart Works Fine on a Low-Carb Diet

Amber Wilcox-O’Hearn explains why.

This cabbage soup only has 9 grams of digestible carbohydrate per 2-cup serving

Your heart beats 100,000 times a day, every day, without rest. You’d think it needs a reliable energy source, and you’d be right. One of Amber’s references (#4) reminds me that, “Fatty acids are the heart’s main source of fuel, although ketone bodies as well as lactate can serve as fuel for heart muscle. In fact, heart muscle consumes acetoacetate in preference to glucose.”

    One of the studies the article links to

    http://www.ncbi.nlm.nih.gov/pmc/articles/PMC292907/pdf/jcinvest00272-0077.pdf

    “Catheterization of cerebral vessels in three obese patients under going 5-6 wk of starvation demonstrated that /8 hydroxybutyrate and acetoacetate replaced glucose as the predominant fuel for brain metabolism.”

    The other studies are either rat studies or cell culture experiments.

    Also – the blog authors state that “Neither of us have medical credentials.” They also state ” Among the works that we have studied, there are many which contradict our thesis, but which we find to be doubtful. If we were to include each of these and our reasons for doubting them, this website would be vastly larger and less readable.

    What are your thoughts on that?

    IMHO – this post of your is inane

    • Hey, Charles.
      You won’t find many people willing to voluntarily undergo cerebral artery catheterization when there’s no immediate benefit to them. If your point is that it’s a tiny study and may not be widely applicable, I agree.
      I don’t see any reason for most people to eat a zero carb diet.
