Yes, actually. In that period I was doing intermittent fasting in addition to running 5k daily. I started at ~210/215 lbs and dropped down to around ~190 or so. Once I started taking meds and winter hit I stopped running so I'm back to around 210.
Anecdotal evidence says this is a valid theory. I personally caused a shingles infection when I was breaking up intramuscular tissues with a lacrosse ball. As well, most massage therapists will have stories about “toxins coming to the surface” for clients after being worked on (especially in first-time clients) (Source: I’ve talked to about a dozen massage therapists about this).
Personally I feel that “toxin” is appropriate language in the massage industry: the actual individual effects can be widely varied, clients understand it, and it prepares them for potential symptoms without planting any negative biases that would affect their actual experience through placebo effect.
