Farmer et al conducted a survey from 1999 to 2004, analysing the diets of vegetarians.
They found that plant based diets were better for weight management.
Vegetarians were leaner that their meat eating counterparts. The plant based folks were found to be naturally eating more magnesium, potassium, iron, thiamin, riboflavin, folate and less total fat.
All in all they found that plant based diets are nutrient dense and can be “recommended for weight management without compromising diet quality” (Tuso, 2013).
