Yes, I can understand how it might appear and sound. But, we are largely not realizing that the only thing that truly heals the body is the body, when it has the materials to work with and the time and space away from unnecessarily having to digest and process food unnecessarily like we have been marketed and conditioned to believe that we need.
One of the reasons that we especially lose our appetites when we are under the weather is because the body is doing its best to prevent any unnecessary tasks while it handles the very immediate and pressing challenges of suppressing whatever has gotten a bit out of control that the immune system is working to eradicate and heal.
The body is constantly working to heal and repair and regenerate but we are often bombarding the body with toxins in and on our bodies, let alone all of the detrimental ingredients that go into most popular and common foods.
Aside from straight-up fasting, whether dry or wet, another good practice that I have been implementing is omad. One meal a day. That gives a large fasting window every day and can definitely have acumulative and beneficial effects!
