Key Differences in Summary

Carbohydrate Restriction: Keto is the most restrictive regarding carbs to maintain a state of ketosis. The Atkins diet starts with very low carbs but gradually reintroduces them in later phases. The Paleo diet is not necessarily low-carb; it focuses on whole, unprocessed carb sources (fruits, starchy vegetables).
Dairy: Dairy is a staple in both the Keto and Atkins diets to provide necessary fats and protein, but it is generally excluded on the Paleo diet because it was not available to hunter-gatherer ancestors.
Grains and Legumes: All three diets exclude grains. Legumes are excluded from Paleo, but some can be consumed in the later stages of the Atkins diet.
Focus: Keto focuses on specific macronutrient ratios (high fat, moderate protein, very low carb). Paleo focuses on food quality and historical consumption, emphasizing organic and grass-fed options. [12, 14, 19, 20, 21]
