A lacto-ovo vegetarian diet is a plant-based diet that includes dairy products and eggs but excludes meat, fish, and poultry. The word lacto refers to milk, and ovo refers to eggs. People may choose this diet for health, environmental, or ethical reasons. Research suggests that lacto-ovo vegetarians have a lower risk of developing type 2 diabetes, gallstones, and certain cancers, as well as improved heart health and weight management. However, it is important to plan this diet carefully to ensure adequate nutrient intake and avoid potential health risks.

Health Benefits
A lacto-ovo vegetarian diet can have several health benefits. Firstly, it can help lower blood pressure and improve heart health. Research has shown that vegetarian diets improve blood flow to the heart and blood vessel health, reducing the risk of heart disease.
Secondly, a lacto-ovo vegetarian diet is associated with a reduced risk of type 2 diabetes. This is because it increases the intake of healthy foods, such as whole grains, fruits, vegetables, legumes, and nuts, and decreases the consumption of saturated and trans fats. Vegetarian diets have also been shown to improve insulin sensitivity and blood sugar control.
Thirdly, this diet can support healthy weight loss. Vegetarian diets are typically high in fibre and low in calories, which can help with weight loss and prevent obesity and related diseases. Additionally, plant-based diets are often lower in calories than meat-based diets, which can contribute to a lower body mass index.
Furthermore, a lacto-ovo vegetarian diet is linked to a reduced risk of certain cancers. Research has found that vegetarians have an 8% lower risk of dying from cancer compared to omnivores. This may be due to the higher consumption of plant-based foods, which are rich in nutrients and antioxidants, and the lower intake of processed meats, which have been associated with an increased risk of certain cancers.
Finally, a lacto-ovo vegetarian diet can provide adequate nutrition for most people. While some may worry about nutrient deficiencies, this diet includes various protein sources, such as eggs, dairy, beans, legumes, nuts, and seeds. It is important to note that certain groups, such as older individuals, may need to be mindful of nutrient intake and consider supplements to ensure they meet all their nutritional requirements.

Weight Loss
A lacto-ovo vegetarian diet is primarily plant-based and includes dairy and eggs, but excludes meat, fish, and poultry. This diet can be an effective way to lose weight, as it is typically high in fibre and low in calories, which can help you feel full and prevent overeating.
Vegetarian diets have been shown to help prevent and reverse obesity and obesity-related diseases. Research has found that vegetarians have a lower body mass index (BMI) than omnivores. A higher BMI is associated with high protein and low fibre intakes, indicating that the lacto-ovo vegetarian diet's high fibre content may be beneficial for weight loss.
The diet's emphasis on whole grains, fruits, vegetables, legumes, nuts, and seeds can contribute to weight loss. These foods are rich in fibre and provide essential nutrients, helping to regulate blood sugar and improve overall health. Additionally, dairy products and eggs, which are included in the lacto-ovo vegetarian diet, can be part of a balanced weight loss plan when consumed in moderation. Dairy provides protein, fat, and micronutrients like vitamin B12, calcium, and zinc, while eggs are an excellent source of high-quality protein, B vitamins, and anti-inflammatory compounds.
It is important to note that while the lacto-ovo vegetarian diet can support weight loss, proper planning is essential to prevent adverse health effects and nutrient deficiencies. For example, individuals following this diet should be mindful of their protein intake, ensuring it makes up about 20% of their total calorie consumption. Additionally, it is recommended to limit high-fat dairy products and prioritise low-fat or non-fat options to maintain a healthy weight.
Before starting any new diet, it is always advisable to consult a registered dietitian who can assess your individual nutritional needs and help you define your health goals. They can create a customised meal plan to ensure your diet is balanced and meets all your nutritional requirements.

Religious Reasons
Lacto-ovo vegetarianism is a type of vegetarian diet that forbids animal flesh but allows for the consumption of animal products such as dairy and eggs. In Western English-speaking countries, the term "vegetarian" usually refers to this type of diet. However, in India, lacto-ovo vegetarians are known as "eggetarians" since the term vegetarianism is synonymous with lacto-vegetarianism, excluding eggs.
Lacto-ovo vegetarianism is prevalent among followers of Indian religions like Hinduism and Buddhism, with millions of Hindus being lacto-vegetarians. In Hinduism, cows are considered sacred and are believed to provide nutritious and life-supporting milk, a gift from nature. The yoga system of living and health also promotes vegetarianism, as it is believed that healthy food contains prana, or universal life energy, which is abundant in fruits, grains, nuts, and vegetables, but absent in meat.
Some Buddhists in Japan and China also follow a vegetarian diet due to their spiritual beliefs. Additionally, traditional cultures in the Middle East and Mediterranean regions have diets that consist mainly of lacto-ovo vegetarian foods. For example, Trappist monks in the Roman Catholic Church and Seventh-Day Adventists are vegetarian. The Seventh-Day Adventists, a Christian sect founded by William Cowherd in 1809, promote the consumption of eggs, dairy, and honey as God's given food, referring to the Bible verse "the promised land flowing with milk and honey" (Exodus 3:8).
The Namdharis, a Sikh sect, also follow a strict lacto-vegetarian diet, quoting verses from the Guru Granth Sahib that endorse vegetarianism and advocate for cow protection. They believe that living in a way that reduces the suffering of other living beings is necessary to attain higher levels of spiritual health.

Ethical Reasons
A lacto-ovo vegetarian diet is a plant-based diet that excludes meat, fish, and poultry but includes eggs and dairy products. Ethical reasons for adopting this diet vary and may include religious beliefs, environmental concerns, and animal welfare.
Many individuals in Indian religions like Hinduism and Buddhism are raised as ovo-lacto vegetarians or lacto-vegetarians. Consumption of eggs is, however, not considered part of a vegetarian diet in India, as eggs are seen as an animal product that gives birth to the next generation of that species. Those who consume eggs but not other non-vegetarian products refer to themselves as 'eggitarians'. The Bible Christian Church, founded by William Cowherd in 1809, promoted the use of eggs, dairy, and honey as God's given food, and many Seventh-day Adventist followers have recommended a similar diet since the late 19th century.
Environmental concerns may also play a role in ethical reasoning. Plant-based diets are associated with lower environmental impacts, including reduced land use, water use, and greenhouse gas emissions. Additionally, the production and consumption of meat, particularly from intensive animal farming, have been linked to environmental degradation and climate change.
Another ethical consideration is animal welfare. The avoidance of meat, fish, and poultry in a lacto-ovo vegetarian diet aligns with the belief in minimizing animal suffering and exploitation. This belief stems from the idea that animals are sentient beings capable of experiencing pain, fear, and distress, and that raising and slaughtering animals for food causes unnecessary harm.
Furthermore, some ethical considerations may arise from the potential health benefits associated with a lacto-ovo vegetarian diet. Research suggests that this diet may reduce the risk of coronary artery disease, improve blood vessel health, lower blood pressure, and decrease the chances of developing certain types of cancer. These health benefits can be attributed to the diet's emphasis on whole, unprocessed plant foods, which are high in fiber and low in calories, promoting a healthy weight and potentially preventing obesity-related diseases.

Environmental Reasons
A lacto-ovo vegetarian diet is a plant-based diet that excludes meat, fish, and poultry but includes eggs and dairy products. This type of diet is associated with several environmental benefits.
Firstly, a lacto-ovo vegetarian diet has a lower environmental impact than an omnivorous diet. Research has shown that omnivorous diets generate worse carbon, water, and ecological footprints than lacto-ovo-vegetarian diets. Meat, fish, and other animal-based foods are the largest contributors to the environmental footprints of omnivorous diets. By eliminating these foods, lacto-ovo vegetarians can significantly reduce their carbon, water, and land use.
Secondly, a lacto-ovo vegetarian diet can help to reduce the impact of factory farming and industrial animal agriculture, which have been linked to various environmental issues. These include greenhouse gas emissions, water usage, and land degradation. By reducing the demand for meat and other animal products, lacto-ovo vegetarians can help to decrease the environmental impact of these industries.
Additionally, a lacto-ovo vegetarian diet can promote the consumption of locally sourced and seasonal produce. Plant-based diets often rely on fruits, vegetables, grains, and legumes, which can be grown locally and sustainably. This reduces the environmental impact of transportation and encourages more sustainable farming practices.
Furthermore, a lacto-ovo vegetarian diet can help to conserve water resources. Meat production, especially beef and other red meats, requires significantly more water than plant-based foods. By eliminating or reducing meat consumption, lacto-ovo vegetarians can contribute to water conservation and reduce the strain on freshwater resources.
Lastly, a lacto-ovo vegetarian diet can help to preserve biodiversity and ecosystems. Meat production often involves the destruction of habitats, such as forests and grasslands, to create grazing land for livestock. By reducing the demand for meat, lacto-ovo vegetarians can help protect these habitats and support the conservation of diverse plant and animal species.
