do bodybuilders really need?

1G PROTEIN PER 1 LB OF LEAN BODY WEIGHT. MANY BLOGS AND FORUMS SAY UP TO 1.5 OR 2G.Bodybuilding websites recommend


1g

Confusion & lack of information equals poor gains

WITH SUCH VARIETY IN OPINION THE NOVICE LIFTER IS LEFT

TO PONDER THE QUESTION HOW MUCH PROTEIN DO I REALLY

NEED IN ORDER TO GAIN MUSCLE MASS EFFECTIVELY?!

So who is right?


Uhh, My one friend told me...

MY research shows...

Where can we get

the proper information?

Where can we get

THE BODYBUILDING MAGS AND WEBSITES ARE FLAT OUT

WRONG. THEY ARE TRYING TO SELL PRODUCTS NOT INFORM.

Tarnopolsky et al. (1988)

This finding has been replicated in several studies:

was needed than for novice bodybuilders.

Rennie & Tipton, 2000; Hartman, Moore & Phillips,

2006; Moore et al., 2007.

Elite bodybuilders build less muscle

THE MORE ADVANCED YOU ARE,the less protein synthesis increases after training.

AS YOU BECOME MORE MUSCULAR AND YOU GET CLOSER TO YOUR GENETIC LIMIT, the less muscle you build after training.

Cutting for competitionsWalberg et al. (1988) studied cutting weightlifters and they still found 0.73g/lb was sufficient to maintain lean body mass.


Pikosky et al. (2008) demonstrated that cutting at a daily 1000 calorie deficit when eating 0.82g protein per Lb of body weight has been shown not to affect nitrogen balance or whole body protein turnover.


Pikosky et al. (2008) demonstrated that cutting at a daily 1000 calorie deficit when eating 0.82g protein per Lb of body weight has been shown not to affect nitrogen balance or whole body protein turnover.

Therefore, you do not need more protein to preserve or gain muscle when cutting compared to when bulking, not even during periods of drastic energy shortage.

0.82There is no advantage to consuming more than 0.82g/lb of protein per day to preserve or build muscle.

ConclusionsThere hasnt been any recorded advantage of consuming more than 0.64g/lb.

Optimal protein intake decreases with training age.

0.82There is no advantage to consuming more than 0.82g/lb of protein per day to preserve or build muscle.

Conclusions

The take home message in 6 words:

Consume 0.82g/lb of protein every day.

There hasnt been any recorded advantage of consuming more than 0.64g/lb.

Optimal protein intake decreases with training age.
