There is no one right way to eat.  It is all about finding the foods and dietary style that makes your body feel good. I have helped clients incorporate paleo, vegan, gluten-free, FODMAP, AIP, Mediterranean, Keto, Intermittent Fasting and others.
Personally, I use a whole food plant-based diet.But I am flexible, and incorporate aspects of many different diet styles according to what makes me feel my best. You can too.
