Yes. Husband and I both had COVID in late May. We were both on Paxlovid. He had a rebound case, I didn't. We have both been following a ketogenic diet since January 2020, and had significant weight loss. Since May, I have gained back 25 pounds of my 95 pound loss, and he has gained back about 20. We have literally had NO change in eating habits since our bouts with COVID in late May - although we have stopped exercising regularly due to fatigue. I have undergone numerous blood and heart tests, as well as an abdominal CT scan with contrast. The only issue that I seem to have is damage to my right lung. Again, like the other posters, the weight gain is predominantly in my abdomen. Since we live near Baltimore, we are hoping to get referred to the Johns Hopkins Long COVID program.
