Whey Protein: The Breakfast of Champions....I Mean Superhereos

Good news. I just came across an article that says whey protein, one of the key ingredients in Accelerade, ( my long distance training drink) can help you lose weight, improve insulin sensitivity, and increase muscle mass.

Now get this: It may also be able to reduce stress, moderate cortisol, and support healthy serotonin levels, thus imparting feelings of well-being. In other words: help fight off depression.

And, the cherry on top?

These findings add to whey’s already well-established benefits, which
include boosting glutathione levels, facilitating immune function, and
aiding in the fight against cancer.

......

One of the study’s most interesting findings relates to body weight, which increased in the group receiving food and supplements compared to the fasting group. In the groups that received either glucose or whole-milk protein, the increase in weight was from body fat. However, in the whey-fed group, the weight increase reflected an increase in muscle mass and a decrease in body fat.3 Whey thus appears to be the preferable choice for supporting improvements in body composition.

......

Whey may also support weight loss by modulating levels of the crucial neurotransmitter serotonin. Serotonin is involved in a wide range of psychological and biological functions, and influences mood, anxiety, and appetite. Healthy levels of serotonin are correlated with relaxation, calm, and an improved ability to cope with stress, whereas lower levels are associated with depression, anxiety, and poor appetite control.
Since serotonin is derived from the dietary amino acid tryptophan, scientists have speculated that increasing dietary tryptophan might increase serotonin levels. A recent study conducted in the Netherlands examined whether supplementing the diet with whey-derived alpha-lactalbumin, a tryptophan-rich whey constituent, would influence plasma tryptophan levels, reduce depression, or modulate concentrations of cortisol, the so-called “stress hormone.”

No wonder you Ironmen are so Iron! I think I might go get some right
now. ...Actually, maybe my next project will be to buy some whey protein and make my own drink, without all that succrose and food coloring.

It is a fascinating article. GO read it!

I've just posted a couple entries about this very subject (linking to the same study from Life Extension, I think). I'm going with a "dutch-chocolate" whey protein. I wish it didn't have spenda in it, but then it would probably be totally undrinkable.

Can you tell I've been reading your blog? Credit goes to RVA Foodie for finding the Whey Protein article.
About the Splenda, I know it is better than Sweet Evil , but still, why not make your own drink using a natural sugar?
I was worried about finding a plain version that was from a reputable company. Any ideas?
