Researchers in Canada found that individuals who worked out and then ate 6 ounces of cooked ground beef (2x the recommended amount of protein in a meal), maximized their muscle growth verses those who only consumed 2 to 4 ounces. Those who consumed 2-4 ounces may not have consumed enough protein to preserve lean muscle (much less grow new muscle).
To enhance the growth of new muscle, lift weights and consume high quality protein. Having a hard time getting enough protein in on a daily basis, consume a 10 ounce smoothie with my Protein Fuel. It is plant based protein source that is easily digestible and has a powerful amino acid profile to build new muscle.
Please let me know if you have any questions about protein intake or need anything clarified!
