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.

The article starts out by kind of trashing the idea of intermittent fasting. It snarkily criticizes people for the use of common sense and logic behind the idea of prehistoric people not eating three meals a day and by necessity following an intermittent fasting lifestyle.
Then it goes on to explain that the people being criticized are perhaps correct. It just says correct for the wrong reasons. Don’t intermittent fast because you believe it is part of how our species evolved. Intermittent fast because science backs it up. Either way, both sides of their opinion makes sense. Even if they don’t want to embrace common sense and logic.
Up until about 12,000 years ago, all humans got their food by hunting, gathering or fishing. As foragers, they would fast until they found, caught or killed their food. There was no breakfast upon waking,, or leftovers for lunch. They ate opportunistically, Freedman and Pobiner say, consuming anything they could get their hands on.Inverse.com
Contrary to what Paleo diet enthusiasts might say, there was no single diet that prevailed; the diets of hunter-gatherers depended largely on location, season, and opportunity. In the polar regions, Eskimo communities relied on wild animal protein, while the Juǀʼhoansi in Southern Africa ate mostly wild plant foods. There was no neighborhood bodega or Trader Joe’s to pick up mango during winter.
