We've been trying to unravel the metabolic syndrome for years and while it is interesting, we certainly won't find the magic bullet during a pandemic. I've been perusing the literature on obesity and immunity and of course it's wildly complicated as expected. I suspect that there is an immunological reserve issue with MetS. This could explain the seemingly paradoxical data which shows things like increased WBC counts and inflammation, alongside various immunosuppressive findings. The idea being that in a person with MetS, the immune system has been working overtime for years and the reserve forces are spent. So when an infection comes along, there is very little thymic or lymphoid function left, and the battle-weary T-cells left on the frontlines are exhausted. Here's a good snippet from one review on it, but there are many examples.
Several studies have further demonstrated the complications of obesity after influenza exposure. Diet-induced obesity has been shown to impair memory CD8+ T cell responses to an influenza virus infection, resulting in increased mortality, viral titers in lung, and worsened lung pathology (37). These adverse effects were associated with an obesity-induced failure to maintain influenza-specific CD8+ memory T cells, which are essential in ensuring vaccine efficacy (37). Accordingly, obesity has been shown to increase the risk of vaccine failure, including the vaccines for hepatitis B (70), tetanus (72), and influenza (17). Obesity is also associated with a greater risk of influenza-related complications and hospitalizations (73,74).
But what does this mean for your average, middle-aged slob like myself and many others, who may not be technically, or extremely obese but definitely metabolically-challenged and tied to an office chair? It's definitely too late to reprogram your metabolism during a pandemic. But if the above is true, then priming the immune system may just be whipping those battle-weary soldiers who are already lying half-dead on the battlefield. So rather than a T-cell immunotherapy approach, perhaps focus on innate immunity (NK cells)
Potential strategies given the above:
1. Innate immunity - generally this goes up with aging and obesity perhaps as a compensatory. It is possibly even the cause of inflammaging. However, it is at least still largely intact and harder to exhaust and therefore may be helpful if stimulated before infection and in relatively younger and less MetS subjects
a. Mushrooms, etc.
2. Rebooting T-cell immunity - Fasting is the easiest way to do this if you can do it. But it takes several days and if you get infected during the reboot I'm not sure what would happen. Senolytics probably help here, but these are things that should have been done long before infection
3. Rejuvenating thymic and lymphoid function
a. Melatonin - looking pretty great as both a short term and longer term helper here
Given the temporary nature of the crisis, I suspect most people can just wily-nily stimulate the heck out of their immune system for a couple months unless they fall into one of the more vulnerable groups which may need a more subtle approach.
A little incentive for the group, anything that "solves" viruses would also likely "solve" cancer, so there's that.
