The Real Deal on Beef Protein: Research Review
The Real Deal on Beef Protein: Research Review
Clinical research is proving what strength athletes have known for decades: BEEF BUILDS MUSCLE!
By Team MD
For years, bodybuilders have been consuming copious amounts of protein along with weight training to increase muscle mass. Clinical research has shown over the years what strength athletes have known for decades: BEEF BUILDS MUSCLE! And more lifters are choosing beef as a preferred source of protein.
Over the past decade, researchers have been studying the effects of beef protein isolate supplementation on muscle building and performance. One study shows that BEEF outmuscles whey! Researchers found beef protein isolate increased arm and thigh muscle circumference better than whey protein isolate.
Beef is a powerful food that can be used to spur muscle growth and anabolism in athletes, and beef protein isolate is becoming a preferred protein choice for supplementation to meet their protein needs.
Beefed-up Research
Ongoing research published in peer-reviewed journals continues to elucidate the credibility of beef protein isolate as a superior protein alternative to other proteins that promotes lean muscle and strength (Sharp et al., 2017). Researchers also demonstrated that beef supports mTOR activation relative to whey protein – a key molecular signal that increases muscle protein synthesis (Detzel et al. 2015, ISSN Poster).
Greater Gains in Mass and Strength
Sharp et al. compared the effects of post-exercise consumption of two servings of beef protein isolate or whey, versus a maltodextrin control, on lean mass and strength during eight weeks of resistance training. Researchers found that beef protein isolate resulted in greater gains in lean body mass than whey protein isolate, and that beef protein isolate significantly increased strength.
Thirty college-aged, resistance-trained males and females were randomly assigned to one of three groups; subjects consumed two servings (46 grams) of beef protein isolate, whey protein isolate or maltodextrin. Subjects trained five days per week (three resistance training, two cardio) for eight weeks. Two servings of protein were consumed immediately following exercise or at a similar time of day on off days. Beef protein isolate led to a greater increase in lean body mass than whey protein isolate, compared to baseline. Lean body mass in subjects consuming beef protein isolate post-workout increased 5.7 percent compared to whey protein isolate (4.7 percent). One-repetition maximum (1RM) in both the deadlift and bench press significantly increased for all treatment groups when compared to baseline.
The researchers concluded: “Consumption of two servings of beef protein isolate or whey resulted in significant gains in lean body mass over time, which outpaced gains resultant from resistance training alone (maltodextrin supplementation).
“Consuming two servings of either beef protein isolate or whey protein isolate following resistance training lead to significant increases in lean body mass and strength.”
Outmuscles Whey to Build Arm and Thigh Mass
Naclerio et al. examined the impact of ingesting hydrolyzed beef protein, whey protein, and carbohydrate on strength performance (1RM), body composition, limb circumferences and muscular thickness, following an eight-week resistance-training program. Researchers found that beef protein isolate outperformed whey for increasing muscle thickness in the arms and thighs – only subjects ingesting beef protein isolate increased arm (4.8 percent) and thigh (11.2 percent) circumferences.
The researchers concluded: “Protein-carbohydrate supplementation supports fat-free mass accretion and lower body hypertrophy. Hydrolyzed beef promotes upper body hypertrophy along with similar performance outcomes as observed when supplementing with whey isolate or maltodextrin.”
Increase in Lower Limb Muscle Strength
Valenzuela et al. conducted a systematic review and meta-analysis of randomized controlled trials that compared the effects of exercise training combined with beef protein, whey protein or no protein supplementation, on body composition or exercise performance. Researchers noted that beef protein “significantly increased total daily protein intake, lean body mass and lower-limb muscle strength.”
The researchers concluded: “Beef protein provides similar effects to whey protein on protein intake and body composition and might be an effective intervention to increase total daily protein intake, lean body mass and lower-limb muscle strength.”
Significant Benefits in Body Composition
Sharp et al. also compared the effects post-workout consumption of beef protein isolate, hydrolyzed chicken protein or whey protein concentrate, compared to a control, on body composition and muscle performance during eight weeks of resistance training.
The researchers concluded: “Overall, the results of this study demonstrate that consuming quality sources of protein from meat leads to significant benefits in body composition compared with control.”
Protein Hydrolysate Better Than Intact Protein
Koopman et al. found that protein hydrolysate, as opposed to its intact protein, is more easily digested and absorbed from the gut, which results in greater plasma amino acid availability and a greater muscle protein synthetic response.
The researchers concluded:“Ingestion of a protein hydrolysate, as opposed to its intact protein, accelerates protein digestion and absorption from the gut, augments postprandial amino acid availability, and tends to increase the incorporation rate of dietary amino acids into skeletal muscle protein.”
More Favorable Anabolic Environment
Valenzuela et al. analyzed the effects of beef protein supplementation on a group of male elite triathletes (Spanish National Team), compared to an isoenergetic carbohydrates supplement.
The researchers concluded: “Beef protein supplementation seems to facilitate a more favorable anabolic environment (i.e., increased TCR [testosterone-to-cortisol ratio] and muscle mass) in male elite triathletes, with no impact on hematological variables.”
Lactose Free
Another key benefit of beef protein isolate is that it’s lactose free, and better tolerated than dairy protein by many individuals. This is a huge advantage, considering roughly 70 percent of the population is lactose intolerant. People with lactose intolerance are unable to fully digest the sugar (lactose) in milk. As a result, they have diarrhea, gas and bloating after eating or drinking dairy products. Too little of an enzyme produced in your small intestine (lactase) is usually responsible for lactose intolerance.
Game Changer for Building Muscle
Mounting scientific research proves what strength athletes have known for years: CARNIVOR™, the clinically backed hydrolyzed Beef Protein Isolate from MuscleMeds, changed the industry and gave athletes a new protein source to reap the benefits of beef and pack on muscle. CARNIVOR™ is the world’s first and best-selling pure beef protein isolate, and delivers all the muscle-building powers of beef and more! CARNIVOR™ is also hydrolyzed into di- and tripeptides, for faster absorption into the bloodstream. This may result in greater muscle growth and recovery. CARNIVOR™ is fat and cholesterol free, so it doesn’t pose any health risks, in addition to being lactose free.
