get an isolate, dont use a concentrate. Ton of threads on this btw.

Subjects included 14 diet-treated type 2 diabetics. They were served a high-glycemic index (GI) breakfast--white bread--and subsequent high-GI lunch--mashed potatoes with meatballs. The meals were supplemented with whey on one day; whey was exchanged for lean ham and lactose on another day. Blood samples were taken before and during 4 hours after breakfast and 3 hours after lunch. Blood was analyzed for glucose, serum insulin, GIP, and GLP-1.

 

The insulin responses were higher after both breakfast (31%) and lunch (57%), when whey was included in the meal than when whey was not included. After lunch, the blood glucose response was significantly reduced [-21%; 120 minute AUC] after whey ingestion. Postprandial GIP responses were higher after whey ingestion, whereas no differences were found in GLP-1, between the reference and test meals.

Yea it can i remember when i use to take it my acne gradually got worse as time passed by then i thought that it was the flavor (i had chocolate) so i switched to vanilla and it was tyhe same so i decided to stop using it for about 3 months and saw my acne inprove not drasticly but it did improve so i dont take it anymore...i get most of my protein now from foods like chicken meat ect.

In other words, yes.

 

Bullshit study.

There are different types of whey proteins. That one doesnt even specify which type of whey was used (Isolate on Concentrate) or brand (MANY contain artificial flavors and shit like aspartme but some have good natural sweeteners like stevia)

Here:

It's the leucine in the proteins. They speculated insulin has to have been secreted first for leucine to augment it. So, this study takes into account of whey protein and whey protein hydrolysate without carbs:

Still has an effect.

Maybe it'd be okay if you were fasting, but I dunno. On the wiki page for bovine serum albumin, one of the proteins in whey, it says that it can bind steroid hormones, which I guess is where the antibiotics and hormones town cryers come from, but I bet that the hydrolysate process filters them out though.

Whey protein is a dairy product whether it's lactose-free (Isolate) or not and dairy products are usually the most common suspects when people discuss foods that aggravate their acne. This year my skin has been clearer than it's ever been in the past 7 years and this was after I switched from Whey (Isolate) to Hemp protein. The whey protein powder was pretty much the only dairy related food in my diet routine, and (for me) removing it from my diet helped improve my acne.

I wouldn't call the study bullshit.

Sorry for bumping an old post, but I figured this could help those who are struggling with acne while on a weight lifting routine that involves whey protein.

Keep in mind the various qualities of whey protein. They don't even have to list all of the crap that ends up in these whey protein concoctions you find at GNC. The only whey protein i suggest anyone use is an organic whey protein from cows not treated with growth hormones or antibiotics, as well as grass fed. There are a variety of brands online such as Reserve Age Organics, Organic Whey, Source Naturals Whey to Health, Source Organic Whey, etc. And i'd never consume a whey protein concoction that is purely whey mixed with fluid. I always added fruit/spinach and made a smoothie in order to prevent constipation.

These organic varieties are a bit more pricey, but you get what you pay for

If you think the whey may be causing your breakouts you may have a dairy intolerance. More than 1/2 of the American people have issues digesting milk and the don't even know it. I was recently tested for food intolerances (note this is not an allergy test) and my intolerance to milk and eggs were off the charts. I immediately started cutting out milk products. My skin cleared up, I felt better and so did my stomach. Eventually, I started experimenting with cheese. Good news is that pizza on occasion does not bother me. I can also eat egg and ice cream once in awhile. However, I have to make sure that those foods are the only milk products I eat for the day or the intolerance kicks in. I suggest you switch to a non-dairy version for your protein shake like Vega One or Vega One Sport. These shakes are made with pea protein or hemp protein Find a few brand and only buy the single serving packets to test them out. Some of these non-dairy version taste nasty. However, if you add fruit or other things to them they state pretty good. I would do this for at least a month and see how your skin looks and how you feel.

You I have always thought to stay away from milk and milk related products.

But recently I saw this post about a supplement called lactoferrin, it is basically like a probiotic and it from whey.

Right now I just have a lot of tiny whiteheads and under the skin red bumps everywhere, but I used to have cystic acne ( it was so bad, it was covering both sides of my face) but I've been able to kinda control that now with SA (stridex pads). Well I'm going to give the lactoferrin supplements a shot, and see if it helps.

This is it : http://m.vitaminshoppe.com/mobile/store/en/browse/sku_detail.jsp?id=JF-7265

Right now if you buy them online they're on sale for 26$, but i actually went in store and bought them for 35$

Anecdotally Whey is notorious for causing acne. Also BCAAs.

Whey protein causes an insulin increase as a result of being a fast-digesting form of protein, which is why it is usually used in protein shakes. Insulin response helps people put on muscle mass quickly. Insulin response is bad for acne. So, its up to you to decide to take it or not.
