Keto and paleo overlap on whole-food preferences, but keto is defined by carbohydrate restriction while paleo is defined by food ancestry rules.

Keto changes what you eat, while intermittent fasting changes when you eat; some people combine them, but they solve different problems.

A cyclical ketogenic diet alternates low-carb phases with planned higher-carb refeeds, which can suit some advanced trainees but often adds complexity without clear benefit for beginners.

The main keto variants differ by how much carbohydrate flexibility they allow and how closely they match training or body-composition goals.

Fasting can raise ketones faster for some people, but it is a timing tool, not a guarantee, and it works best when the rest of the diet already supports lower carbohydrate intake.

Ketovore is a meat-heavy version of keto that can simplify food choices for some people, but it can also narrow fiber and micronutrient intake more than standard keto.

Keto can lower potassium intake if produce variety drops, so choosing low-carb foods that still carry potassium is a practical way to support the diet.
