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.

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.

If that weren’t enough to set me off, consider the overall weakness of this study, and the choice of the word “proven” borders on journalistic manslaughter.

That just floored me. Is there a connection between physical and emotional pain tolerance?

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.
