When it comes to losing weight, we know diet and exercise play a role.
However, a new study shows it's what you cut out that makes the pounds melt away and boosts metabolism by reducing muscle fat.
That doesn't mean just sugar, but meat has got to go too!
We'd all lose more weight if we went vegetarian, according to new research published in the Journal of the American College of Nutrition.
Making this change can help you lose weight twice as fast, compared to conventional low-calorie diets.

Researchers studied 74 men and women with type 2 diabetes. They were randomly assigned either a vegetarian diet or conventional anti-diabetic diet that followed guidelines from the European Association for the Study of Diabetes.
The vegetarian diet was all about fruits and veggies, grains, nuts and a max of one low-fat yogurt a day.
Everyone restricted their diets by 500 calories a day, so that obviously helped cut weight a little bit.
Researchers found that vegetarian dieters lost an average of 13.7 pounds compared to 7.1 pounds for conventional dieters, nearly twice as much over the course of several weeks.
The vegetarian diet also reduced muscle fat. That's a big deal for people with type 2 diabetes because muscle fat can worsen insulin resistance, according to Men's Fitness.
So if you want to lose weight, I hope you like broccoli!
