Possible Negatives Related to Whey Protein
 
I read an article today that has me concernced, especially because I just began drinking a delicious whey protein shake on my DD's. The article was written by Coach Josh, creator of the 7 day Belly Blast Diet. Please note that at the end of the article he was "pushing" his own form of protein shake.
Anyway, here is a portion of what was said in the article

1. "A review on the rate of protein absorption published in 2006 in the International Journal of Sport Nutrition and Exercise Metabolism reported that whey protein isolate absorbs at a rate of about 8g/hour...Simply put, whey protein passes through the system far too rapidly to be adequately absorbed, leaving the majority of your protein shake wasted…literally.

2. "...a 2012 study published in Nutrition & Metabolism identified that the specific amino acids in whey protein stimulate beta cells to secrete more insulin than a similar amount of carbohydrate from white bread. In the presence of insulin, fat burning essentially stops....The truth is, whey protein simply isn't an ideal protein to use at any other time other than immediately following exercise, and even then the amount you're able to absorb on a per serving basis is extremely limited."

I intend to research the studies he references and see if what he's saying is true.

KelAly8894 07-20-2012 03:54 AM

FYI - I researched both studies, and the studies say EXACTLY what Coach Josh says they say. Well, because I'm not a bodybuilder who could really use whey protein right after an intense workout without the release of insulin causing a problem, I guess I'm throwing out my protein shake mix. Remember, an increase in insulin basically means an end to fat burning. Geesh !!! :stars:

I get Dr. Mercola's newsletter. Today's newsletter was about whey protein. It specifically stated that whey protein is far superior to whey protein isolate.

I think the isolate still contains lactose which can raise insulin.

I occasionally read things from Dr. Mercola, too. If you search his site, there is a ton of well-documented information on whey protein. I also read that protein ISOLATE is not a good way to get protein.

KelAly8894 07-20-2012 06:49 AM

I get Dr. Mercola's newsletter also. The study related to insulin was used using "whey serum". I'm not sure what that means. A quick google of that phrase didn't really shed any light.

I gave up my protein shakes too. I was putting the powder in plain yogurt besides making a shake every day. In April I had decided to (mostly) give up dairy, and then I read some similar things you have about the protein powders (isolate). I decided for my own health I would just give up the protein powders.

KathyL 07-20-2012 07:33 AM

I have stopped haveing them as well and have noticed a difference in my muscles. My workouts seem harder, as if my muscles aren't as strong as they were. And recovery time is longer. Mine has whey protein concentrate and isolate. I stopped mostly because I was incorporating fast-5 with JUDDD so I couldn't have it in the time frame recommended (30 minutes after working out). Now they are saying anytime within 24 hours. Dh feels it hinders his weight loss.

mykidsteacher 07-20-2012 07:38 AM

I use a rice protein powder (allergic to dairy). Any info in those studies regarding different forms of protein?

So Kathy, are you saying you seem weaker after giving up the shakes? Are you planning to add them back in?

KathyL 07-20-2012 08:11 AM

Yes....I definitely feel weaker. There are a couple exercises in particular I have been doing for a year that I now have a difficult time finishing. I'm not sure what I am going to do. I may start the shakes again, but just on the 3 days a week that I do my weight training.

jem51 07-20-2012 08:16 AM

I've never had a problem w whey and use it on occasion when traveling or at work.

Someone over at the ML suggested keeping it in emergency kit.

But really, if it works then great. If not, give it up.

That's the joy of JUDDD; We get to decide.

GME 07-20-2012 08:18 AM

Dang it, just bought a new package.

Any info on egg white protein? I usually buy the Jay Robb brand and once I bought his egg white kind. It is a little pricier, but tasted great. If the whey isn't doing me any good, I am paying too much anyway. :)

I don't drink it as shakes very often, but like to use it in recipes (well, not recipes really, concoctions would be a better word).

piratejenny 07-20-2012 10:10 AM

Kel-- 1st off, absorbing 8g protein per hour is about average*, not terribly fast.

I didn't read the study...but could see it being more of a problem if the entire shake is "passed" out of the body very quickly.

Mixing it with some fiber & fat could slow it down, make it more like a "meal".
Some people use an egg (yolk), almond butter, cottage cheese, yogurt, etc.
I know, prob not great for DDs...
Also, you could mix it with other types of protein powder, if you don't want to waste it.
I like to add a little hemp protein, because it is so high in fiber & healthy fats.

Protein by itself is often "accused" of raising blood sugar.
Protein in a meal, with fat, takes longer to digest and shouldn't cause problems.


The other thing is...if you feel better when you have the shake than when you don't, maybe it's not having the same effect on you. The only way to be sure is to test your blood sugar...but I wouldn't necessarily go to the expense of that if not necessary.

If I understand it correctly, insulin is also how ALL nutrients get into your cells--not just fat. So it can help you get nourishment from your food and make you feel more energetic.

*I happened to read this on Mark's Daily Apple a few days ago:
"But because the pool of amino acid transporters is limited, amino acids are typically absorbed by the small intestine at a rate of 5-10 grams per hour. This would suggest, at first glance, that the original “30 grams of protein per sitting” figure is close to correct. If you can only absorb, say, 7 grams of protein per hour, and the bolus of digested protein and other foods takes 4 to 5 hours to wind its way through the intestine, you’re gonna absorb maybe 28-35 grams. Right?

Not exactly. It turns out that our digestive process is fairly fine-tuned and regulated by the composition of whatever’s being digested. The presence of protein in chyme actually causes the secretion of CCK, a hormone that slows down the intestinal contractions that move food along, thus giving the protein more time to be transported by amino acid transporters. So, while it’s technically true that we aren’t absorbing 30 grams (let alone more) of protein all at once, it will eventually be absorbed."

Gina--I'd imagine that when consumed in recipes/concoctions, protein powders are digested more slowly and therefore not wasted. Egg white powder, in particular, is closer to a "real food" than whey protein, and probably utilized pretty thoroughly.

I avoid whey protein as a vegan, but I also weaned my weightlifting man beast off of it as well (PUSHING my little agenda lately) and at first he was so nervous that he wouldn't be able to lift his max (350) but found after a month of consuming my special shakes that he increased to 360. He was absolutely shocked and really happy. He said he felt much better on my shakes and had more energy throughout the day.

If whey concerns you, try this for a while and let me know what you think!

1c coconut water or filtered water
1/2 avocado
1 scoop hemp protein or SW blend (raw, no isolates)
stevia as needed

KathyL 07-23-2012 11:08 AM

That's good to know Nicki! I have some SW and once my whey is gone I'm going to change things up. Right now I'm starting it back up just on weight training days (usually UDs) and hoping that will help get me back to where I was.

kayellr 02-09-2013 11:22 AM

Well @%#$! I just got some whey protein concentrate (not isolate) and made up a shake (whey, some coconut milk, avocado, eggs, cocoa powder, cinnamon and a bit of xylitol - all things I eat often (not so much the xylitol)). An hour and a half later I started feeling HORRIBLE - weak, dizzy, headachy, shaky. I thought I must not have had enough salt etc, so went and had some bone broth with salt, K and Mg. Didn't help. I wound up having to go lie down! Felt very much like a serious blood sugar crash. :sad:

b_lou_who 02-09-2013 02:34 PM

I use organic hemp protein almost every day. Love it

Yennie 02-09-2013 03:16 PM

PJ's description of protein metabolism and transit time is spot on. The only thing I'd add is that insulin is used to transport glucose into cells, not fat. Fat and protein absorption by cells is dependent in trans-membrane proteins and enzyme processes that are regulated at the cellular level - basically as its needed, each individual cell picks the fatty acids or amino acids (protein) out of the blood stream and whatever is left over gets stored in fat, the liver or muscles.

Thread jack-
Yennie- our height and start weight is the same. I just noticed that.

Lol, I hope I can be as successful as you!!

I don't see why not! Luckily JUDDD is very simple and very forgiving. You are off to a great start it seems.

C'Marie 02-10-2013 10:27 PM

I use whey protein, sometimes isolate and sometimes concentrate. I have had no adverse side effects and in fact feel quite good on it. Although my mother told me that some versions of it create an "ash" upon digestion that leaves our body to deal with, and that it might not be good for some reason. I have used eggwhite protein also.

Kettleboy 02-10-2013 11:54 PM

Really don't think this is an issue for JUDDD'ers, If you were a bodybuilder trying to get a contant Protein feed, then yes. Certainly still better than carbs.
