No Whey Dude… It Really Works to Help Build Mass?

No Whey Dude… It Really Works to Help Build Mass?

No whey?  Yes, way!  This recent study suggests that whey supplements REALLY do work to increase muscle mass in bodybuilders who engage in resistance training.

  • bodybuilders supplemented with 1.5 g/kg of whey isolate for 10 weeks.
  • after 10 weeks, they gained 5 kg of lean mass while losing 1.5 kg of fat mass.
  • the whey protein group also achieved greater strength gains than the control group.

From the study:

“Different dietary proteins affect whole body protein anabolism and accretion and therefore, have the potential to influence results obtained from resistance training. This study examined the effects of supplementation with two proteins, hydrolyzed whey isolate (WI) and casein (C), on strength, body composition, and plasma glutamine levels during a 10 wk, supervised resistance training program. In a double-blind protocol, 13 male, recreational bodybuilders supplemented their normal diet with either WI or C (1.5 gm/kg body wt/d) for the duration of the program. “

What does this mean? To start off with, the study group who consumed whey protein did experience greater improvements in strength and lean muscle mass compared to the control group who consumed casein. In practical terms, adding 5kg of lean muscle mass is quite significant in just 10 weeks time.

What’s more, is that the group who consumed whey protein also lost 1.5 kg of fat during this time period.

    Hi , this is jyoti from india.I wnat to know that whether WHEy can be useful for Osteoarthritis & High Blood Pressure patients.

      Jyoti, I'm not personally aware of any potential benefits of whey protein for either osteoathritis or high blood pressure. I did a quick search of PubMed, and there was one study where they looked at the effects of whey protein supplementation in patients with hypertension, but did not find any benefit:
