COVID-19 Outbreak Information Updates (Reboot) [over 150.000,000 US cases (est.), 6,422,520 US hospitilizations, 1,148,691 US deaths.]
So you'll glibly, and wrongly, dismiss actual research on the grounds that "Many medical professionals are going to dismiss fasting because they(and big pharma) can't make any money from it." Because they make so much money from the usual treatment for long Covid and other chronic fatigue conditions (i.e. mostly shrugging and "maybe exercise?").
But then you dump links from a site advertising their thousands of euros a stay fasting clinics and from Gwyneth Paltrow, who'd like you to buy her health advisor's fasting book (from the Goop Press series, foreword by Gwyneth Paltrow, $27.99), and why not support your 'interactive fasting' with herbal non-alcoholic cocktails ($32, or three for $89) and a detoxifying superpowder ($60)?
Get a grip.
