Paleo vs Keto: What's the Difference?
Paleo and keto are the two most-searched whole-food diets — and people constantly mix them up. They share the same enemy (sugar and ultra-processed food) but split on two things: carbs and dairy. Here's paleo in plain terms, and the side-by-side comparison to pick your lane.
What you eat on paleo
- Beef
- Eggs
- Chicken
- Salmon & fish
- Liver & organ meats
- Avocado
- Vegetables
- Nuts
- Fruit & tubers (potato, sweet potato)
What paleo cuts out
- Grains & bread
- Added sugar
- Dairy
- Legumes
- Ultra-processed food & seed oils
Paleo vs keto, side by side
| Paleo | Keto | |
|---|---|---|
| Core idea | Eat like pre-agriculture humans: whole foods only | Keep carbs low enough (20–50 g net) to burn fat: ketosis |
| Carbs | Allowed from fruit and tubers | Strictly limited — the defining rule |
| Dairy | Excluded | Allowed (cheese, cream, butter) |
| Potato & sweet potato | Allowed | Avoided |
| Sugar & processed food | Excluded | Excluded |
| Ketosis | No — carbs stay too high | Yes — the whole point |
The practical answer: if your goal is steady fat loss, appetite control or blood-sugar stability, keto's carb ceiling is the stronger lever. If you mainly want to eat unprocessed and keep fruit and potatoes, paleo is the gentler on-ramp — and moving from paleo to keto is just two steps: drop the tubers, cap the fruit.
A sample paleo day
- 1 Breakfast: eggs scrambled in olive oil with avocado and berries
- 2 Lunch: grilled chicken with a big salad, nuts and olive oil
- 3 Dinner: beef or salmon with roasted vegetables and sweet potato

Frequently asked questions
What's the difference between paleo and keto?
Two things: carbs and dairy. Paleo allows fruit and tubers (so no ketosis) but bans dairy; keto strictly caps carbs at 20–50 g net (ketosis) but welcomes cheese, cream and butter. Both ban sugar and ultra-processed food.
Is paleo a keto diet?
No. With fruit, potato and sweet potato allowed, paleo carbs stay too high for ketosis. A paleo plate becomes keto when you drop the tubers and cap the fruit.
Which is better for weight loss, paleo or keto?
Both work by removing sugar and processed food. Keto adds a stronger lever — the carb ceiling that switches the body to fat-burning and blunts appetite — which is why it's usually the faster tool for fat loss.
What can't you eat on paleo?
Grains and bread, added sugar, dairy, legumes, and anything ultra-processed (including most seed oils).
