Body mass index, Vegetarians, Non-vegetarian.


As obesity rises and pose a serious threat worldwide, people are starting to look for healthier options that would help them lose weight. Along with this, environmental and ethical issues also push people to start a vegetarian diet. This research is helpful to the community as it provides knowledge about the

two different diets and how it affects a person’s BMI. This study examines lacto- ovo vegetarians and non-vegetarians through a questionnaire-style survey

prepared to compare the body mass index, along with the nutritional intake, and their physical activities. The questionnaire was made and shared on various online platforms such as facebook, twitter, Instagram, reddit, and also shared to friends and family through messaging. The results of the research showed that

majority of the respondents had a BMI interpretation of “Normal” for non- vegetarians (50%), as well as for the lacto-ovo vegetarians (61.90%), which

means that the dietary pattern that reflects the healthiest BMI is Lacto-Ovo Vegetarian. Although it reflects as the healthier dietary pattern, the Independent Sample t-test shows that they are not significantly different having a p-value of 0.585 at 0.05 level of significance. The conclusion can be drawn that the BMI of lacto-ovo vegetarians and non-vegetarians are not significantly different, and that there is no significant difference in the nutrition that they acquire.
