This study addresses the reasons for adopting vegetarianism and the health impacts of a vegetarian diet on some people in Lebanon. Results of this analysis will be used to heighten the awareness of the public, health care professionals, government and health agencies on the positive attributions of a vegetarian diet. A cross-sectional study of developmental research was used for this research which consisted of a quantitative approach that used a questionnaire filled by a random sample of respondents. The people surveyed, or the respondents, were individuals exposed (for any duration of time) to any type of vegetarian diet. The hypotheses were tested using frequency analysis, chart analysis and cross-tabulation using the Statistical Package for the Social Sciences (SPSS). The researcher concluded that most of the surveyed people in Lebanon adopt vegetarianism or are interested in this diet for health and religious reasons primarily (specifically Christians during Lent), for a temporary period of time, and they believe it has a positive effect on health especially in preventing some diseases and feeling generally better.
