An Italian study comparing a Mediterranean diet with a lacto-ovo-vegetarian diet for weight control and overall health was published in Circulation in February 2018. The Mediterranean diet focused on fruits, vegetables, beans, and whole grains as well as poultry, fish, dairy, and some red meat. The most common type of vegetarian diet, the lacto-ovo-vegetarian diet included dairy and eggs but no meat or fish. Both diets are widely promoted as being healthful, and previous research has shown that each can improve aspects of cardiovascular health and help with weight control, but no clinical trial has compared them until now.
