This protein-packed powerhouse has benefits beyond great taste.

Lean beef is a complete protein source, containing all the essential amino acids necessary for building and maintaining muscle mass.

A 3-oz serving of T-bone steak contains 22 grams of protein-which, if you’re looking to shed a few pounds, can help you stave off hunger and feel fuller for longer.

A study conducted by Australia’s national science agency found that overweight and obese men using a high-protein diet (with lean red meat) reduced ab fat more effectively than those on a high-carb plan.

Red meat provides the majority of zinc for most Americans, according to the National Institutes of Health.

The high levels of zinc in red meat help ward off illness – and researchers believe zinc can reduce the severity and duration of common cold symptoms.

“Red meat also supplies vitamin B12,” says Jim White, R.D., a spokesman for the American Dietetic Association.

“This helps the body make DNA and keeps nerve and red blood cells healthy.”

A 2012 study published in the American Journal of Clinical Nutrition found that participants who incorporated lean beef into their everyday diet experienced a 10% reduction in their LDL (bad) cholesterol.

The zinc in beef is essential for testosterone production – which helps boost sex drive – and can help reduce blood prolactin levels.

Prolactin is a brain chemical responsible for the refractory period: the amount of time it takes for you to get it back up for Rounds 2 and 3. Less prolactin, less recovery time, better you in the sack.
