Fasting

Learn more about fasting, including types of fasting, fasting metabolism, health effects, and mechanisms of fasting.

My nutritional framework

Nutrition is such a loaded topic—almost a religious or political one—so I’m always looking for ways to explain it that are as free from that baggage as possible.

#84 – AMA #10: Low testosterone, hypothyroidism, building muscle (and preserving it while fasting)

“Milk is for babies. When you grow up you have to drink beer.” —Arnold Schwarzenegger

Can fasting help athletes hold their breath longer?

This was basically the question posed to me by my friend, Justin Lee, a world-class freediver and spearfisherman who is already hard at work training for the 2020 World Championships next Fall.

#80 – Celebrity AMA with Apolo Ohno and Sasha Cohen: Fasting, rapamycin, performance vs. longevity, and more

“I am obsessed with knowing stuff. There’s just no denying it.” — Peter Attia

Qualy #43 – What are Peter’s thoughts on fasting and ketosis for females?

Today’s episode of The Qualys is from podcast #26 – AMA #3: supplements, women’s health, patient care, and more.

Alternate Day Fasting

I’m left bewildered: there are more questions than answers in most scientific pursuits, but I want to stress the point here that these aren’t rhetorical questions.

Can you maintain muscle during fasting?

But in the short-term (at least up to a week for most people), I believe you can maintain muscle mass while fasting, particularly if you’re resistance training.

Can you preserve lean body mass during “semi-starvation?”

All of this is very interesting, but what I find much more interesting in this study is that the placebo group did not lose any substantive LBM, while losing about the same amount of fat (10 lb) as the testosterone group, despite the severe CR/energy-deficit.

Fasting and cancer

The purpose of the study was to find out if fasting could protect the intestines from high-dose radiation, which could allow for higher doses of radiation treatment in killing pancreatic tumor cells.

Fast-breaking without glucose spiking

As I’m coming off of a week of fasting and heading into a week of a ketogenic diet, the timing seems right to address the question of how I break a longer-term fast and the responses that some people get.
