Two common forms of vegetarian diets are absolute vegetarianism (veganism) and lacto-ovo vegetarianism. Veganism is generally not recommended due to the potential lack of essential micronutrients and its restrictive nature. Lacto-ovo vegetarianism, on the other hand, includes all plant-based foods along with dairy and eggs, while excluding other animal products. The inclusion of dairy and eggs in this diet helps prevent protein deficiency issues such as hair loss and sagging skin.

This type of diet can help reduce inflammation due to the absence of red meat and, in many cases, supports more effective weight loss. Thanks to its high fiber content, it may also be beneficial for digestive health and in managing high blood lipid levels. Additionally, it promotes healthier skin and hair due to its richness in vitamins such as C, A, and selenium. However, to avoid micronutrient deficiencies that can result from the exclusion of animal-based foods, it is advisable to take supplements as recommended by a nutritionist. The duration of this diet should also be tailored to the individual's condition and guided by professional advice.
