Whey Protein is WHEY Better than Soy

Whey Protein is WHEY Better than Soy

Whey vs SoyIf you have ever considered losing a few pounds while gaining lean muscle mass than you are likely familiar with the old debate of Soy vs. Whey protein.  Personally I have used Whey protein to lose a few pounds and I have found it to be easily digestible and tastes great.  I have heard many things about Soy protein including that it triggers an increase in estrogen.  So, I wanted to find out which protein is better.

Studies have clearly shown that Whey protein is the better choice for increasing quality protein intake.  Research suggest that the high amino acid content of whey protein supports an optimal rate of protein buildup.

What’s even more interesting is that a 12-week study conducted on two groups of individuals to test the effectiveness of whey protein on weight loss. Showed that groups that incorporated whey protein into their diet had less body fat and better preservation of muscle mass.

So, if you are looking for a protein high in biological value and a high fat loss capability, then Whey protein is the ‘Whey’ to go!
