Once we get into what you can and can’t eat, it’ll be nice to know that your new highly-restrictive diet is only temporary!
The elimination portion of this diet should last approximately three weeks, but I like to shoot for 23 days since that’s how long it takes for antibodies to turn over. Antibodies are the proteins that your immune system makes when it reacts to food. Before you reintroduce foods to your body, you need to give your body time to create new antibodies.
Plus, it’s a standard belief that it takes 21 days to form a habit. After 23 days of sticking to a strict, healthy diet, it’ll be much easier for you to transition those habits into your normal lifestyle.
