Becoming vegan is one of the best ways to lose weight.
Experts have revealed that people who stuck to a plant-based diet lost about 17 lbs compared to those who take a regular approach to eating.
Researchers say vegan diets contain less fat and more fibre, while the findings are consistent with previous studies carried out with vegetarians.
Nutritionist Dr. Ian Johnson, from the Quadram Institute in Norwich, said: "They tend to have a lower BMI and a reduced risk of metabolic diseases, compared with control subjects consuming omnivorous diets, and the differences are greatest for vegetarians who minimise their intake of animal products.
"Over a relatively short period of time vegan diets can offer important health benefits."
Anne-Ditte Termannsen, of the Steno Diabetes Centre in Copenhagen, added: "Adhering to a vegan diet for at least 12 weeks may result in clinically meaningful weight loss and improve blood sugar levels."
