Could be. I’ve been less sick recently. Besides a covid hit last year, I can’t remember being sick. I also incorporate fermented foods in my diet, and also take lots of cold showers. Idk if that helps with the immune system, I’ve heard it does but idk how it would.
I’m only 2 and a half months on IF, and I didn’t even have a cold. I had a covid patient at the house and didn’t cach covid. To be fair, I also took 4 vacancies, but still. I didn’t have headaches since I started taking electrolytes at the beginning of my IF journey, and my tummy pains are gone.
