... After a heroic research effort that took 2.5 years and 500,000 euros, he and his colleagues had managed to shepherd a large group of frail, elderly subjects through a six-month strength-training program. Those who had taken a daily protein supplement managed to pack on an impressive 2.9 pounds of new muscle. Success! Old people could be strong!
... On his phone was a photo one of his students had just sent him of a large plate stacked high with bulging cubes of raw beef. In total, there were 3.1 pounds of beef—a graphic visualization of the muscle lost in just one week by subjects of a bed-rest study the student had just completed.
“I usually put this in more obscene language,” van Loon says, “but you can mess up a lot more in one week than you can improve in six months of training.”Replies

This is significantly out of line with other research I've seen. Marusic et al. (2021) meta-analysis[1] found an average muscle loss of ~2% after 5 days. It did not report average absolute muscle loss, but the average person has about 1/3 of bodyweight as muscle, so at an average weight of ~180 pounds, that would represent 1.2 pounds of muscle loss in a ~week, not 3.1 pounds.
