Damn, that’s one way to sway us to get the vax. Eince this never gets said: To abstain from viral infections like cold and flu, simply keep insulin as low as you can at each meal and fast often. Someone should be able to chime in and explain that they also do not experience cold or flu when eating this way. Ketones change the ph of the blood and lessen the amount of glucose so microbes and viruses can not strive, symptoms are also lessened.
