The ketotarian diet is a plant-based version of the low carb, high fat keto diet.

This diet allows you to experience the benefits of both a vegetarian diet and a keto diet. It also provides some flexibility, as you can eat eggs, ghee (clarified butter), and even fish.

However, it’s restrictive and may be difficult to maintain long term.

Keto is an effective weight loss diet and highly anti-inflammatory. It may help treat type 2 diabetes and certain disorders of the brain and nervous system like epilepsy and Alzheimer’s disease.

Little research has been done on the ketotarian diet specifically. However, keto is a very effective weight loss diet when you also restrict your calorie intake.

Being in ketosis or burning fat for fuel instead of carbs, which happens when you severely restrict carb intake maintains your metabolic rate, or the calories you burn at rest. It can also preserve your lean muscle mass.

One study in 89 people with excess weight and type 2 diabetes found that those on a low calorie keto diet lost more weight and had more improvements in blood sugar control than those on a standard low calorie diet.

In addition, the keto diet balances hormones that play a role in your hunger and fullness levels, resulting in less hunger while in ketosis.

Furthermore, vegetarian diets may also promote weight loss. In a review of studies in over 1,100 people, those on vegetarian and vegan diets lost 2–6 pounds (1–3 kg) more than those on non-vegetarian diets over 18 weeks.

Despite their greater volume, plant foods like non-starchy vegetables typically contain fewer calories than animal foods meaning you can eat large amounts of them for a fraction of the calories found in regular portions of animal foods.

In addition, vegetarian diets are typically high in fiber, and high fiber diets have been linked to improved weight control.

Ketogenic diets, such as the ketotarian diet, are very effective for weight loss. They preserve your metabolic rate and keep you feeling full, making it easier to restrict calories.
