Plant based eating is beneficial, especially when trying to lose weight.
The study linked here, looked at different dietary plans to use while going through a specific weight loss plan. It found that plant based options lead to more weight loss. This can include vegan, vegetarian, and even pesco-vegetarian (allows fish, also called Mediterranean diet). An additional benefit of this style is that you don’t have to count calories. Anyone doing this should still aim for the 40%-30%-30% breakdown of carbs-fat-protein.
