In short, the difference is primarily whether or not you consume processed or unprocessed food. With keto many people eat processed foods because they are just watching their macros. With paleo you can’t eat processed food because you’re restricting yourself to things that the supposed Paleolithic man would have eaten.
To me, it all boils down to what works for you. If sugar causes you trouble then paleo is not for you because it allows for the consumption of honey and many fruits that would cause someone to get booted out of ketosis. If those natural sugars don’t cause trouble then have at it!
The keto and paleo diets are among the most popular diets today. They share some similarities, but there are also differences in the foods they allow, their effects on the body, and key health effects.
The ketogenic (keto) diet focuses on eating a particular balance of macronutrients. The goal is to enter a state of ketosis, where the body begins to burn fat for health or weight loss.
The Paleolithic (paleo) diet focuses on eating foods that humans would have eaten in the Stone Age. The goal is to eliminate modern processed foods for health or weight loss.
