The study subjects in reference 13 were healthy volunteers, mean age 67, maintained on a normal diet. The full text is paywalled, but I can send it to anyone who's interested.
The OP was not on complete bed rest, but the acute phase of recovery from significant injury involves systemic inflammation and a catabolic state, where resources are diverted to healing and anabolic processes, such as amino acid deposition in muscle, is effectively halted.
Most old people are losing muscle at a slow, but measurable, rate anyway and the only way to maintain it is resistance exercise and lots and lots of dietary protein.
I will stand by what I said as the study you posted showed less than 4lbs while confined to complete bed rest. The op is not and is also pity eating.
Interesting read anyways thanks for posting.
