    Study: Low-carb diet linked to increased cortisol & inflammation

    Primal Fuel
    Although participants burned the most energy on the low-carb diet, researchers found that it came at a cost of "increases in cortisol, a stress hormone, and a measure of inflammation called CRP, which can raise the risk of developing heart disease and diabetes.

    The majority of the confidence intervals cross. That means that this study is meaningless due to being underpowered (too few participiants) and should never have been published. The study can't tell you anything about anything. It is the same as knowing nothing.

    This is a good analysis of that particular study:

    Peter does a good job breaking it down (not debunking it mind you).

    There is some truth to this, Low Carb dieting does increase cortisol levels in some people. It happened to Robb Wolf he developed adrenal fatigue at least twice before he figured it out.
    My book Fix Your Gut is available on Amazon http://www.amazon.com/Fix-Your-Gut-D...s=fix+your+gut. The book price is $9.99.

    Also, I have a fundraiser for my new book Fix Your Mitochondria: https://www.indiegogo.com/projects/f...ergy/x/3599154. Please donate if you can.

    Is Robb someone on these boards? Can you tell me how he figured that out, or point me to some links?

    I'm low carb - but not all the time. And my cortisol AFAIK is great. No symptoms. If you're afraid of VLC, or just like to mimick seasonal variety, or fruit and chocolate, etc, just cycle carbs in once in awhile.

    Come on fellas. We all know that low carb done the wrong way (high protein, no carb refeeds) will raise cortisol and adrenalin.

    I don't know that. Never had my cortisol checked. So, technically I don't know it's not true, either way. But I am asymptomatic, even after weeks and weeks of VLC.

    I'm pretty happy on VLC. Had a few cheats but very small in carb terms. Probably 20g a day or less. Don't feel any issues with cortisol and I can work for 10 hours at a stretch without fatigue. Sleeping very well as always. Just have so much more endurance, mentally and physically.
