Two demanding frameworks combined, with real planning required to pull off well.
Ketotarian attempts to combine two often-opposed philosophies — very-low-carb ketogenic eating and vegetarian or vegan eating — relying on plant fats (avocado, coconut, nuts, seeds) and plant proteins instead of the meat-heavy approach typical keto plans use.
| Dimension | Ketotarian | THE FAD |
|---|---|---|
| Core rule | A vegetarian or vegan approach to ketogenic eating — very low carb, but from plant fats and proteins rather than meat | No macro ratio and no food group exclusion required |
| Key challenge | Getting adequate protein and specific nutrients (B12, iron) on a very-low-carb plant-based diet takes real planning | No such constraint, since no macro target exists |
| Overlap | Nuts, seeds, avocado, coconut and non-starchy vegetables — several score well independent of the ketotarian framing | Rewards these foods for their fibre and fat quality regardless of the diet label |
Combining very-low-carb with plant-based eating removes both legumes (too carb-heavy for keto) and most animal protein — the resulting diet requires real planning to avoid protein and micronutrient shortfalls, more so than either keto or vegetarian eating alone.
Non-starchy vegetables, nuts, seeds and healthy fats — the backbone of ketotarian eating — score well on THE FAD regardless of the specific macro framing around them.
The best way to understand the difference is to see what a real day scores.
