Eating Pasture Raised Meat Can Help you Lose Weight.

Pasture raised meat and dairy has fewer calories and fat. It's also nutritionally superior: http://www.huffingtonpost.com/david-kirby/the-nutritional-superiori_b_517707.html

Even if you eat a typical amount of beef (66.5 pounds a year), switching to lean grass-fed beef will save you 17,733 calories a year. That means that even if everything else in your diet remains constant, you'll lose about six pounds a year.

I would, of course, recommend also reducing the amount of beef you consume, and adding more fresh fruits and vegetables.
