It’s pretty confusing out there, if you pay attention to what everyone is saying.
Paleo, low carb, plant-based, Vegan, omnivore, keto, intermittent fasting …
… breatharian, lacto-ovo-vegetarian, dairy-free, gluten-free, casein-free …
… I could go on.
What’s not confusing is simple experimentation on yourself.
Try some things, and see if they work, or not.
You can always trust what your body says.
