What type of diet excludes all animal products?

A diet that excludes all animal products is referred to as a vegan diet. This means that individuals following this diet do not consume meat, dairy, eggs, or any other ingredients derived from animals. The focus of a vegan diet is primarily on plant-based foods such as fruits, vegetables, grains, legumes, nuts, and seeds.

In contrast to this, vegetarian diets can vary; some vegetarians do consume dairy products and eggs (lacto-vegetarians and ovo-vegetarians, respectively), which means they do not fully eliminate all animal products. Pescatarians include fish and seafood in their diets, which also does not align with a completely animal product-free diet. The keto diet is characterized by high fat and low carbohydrate intake and can include animal products, so it does not match the definition in the question.
