Does Whey Protein Help With Weight Loss? | Ask The Fitness Nerd

Is the whey protein-weight loss connection fact or fiction? Find out from the Fitness Nerd if using whey protein for weight loss is “yeah” or “nay. “

Dear Fitness Nerd,

I have a question for you around whey protein and weight loss.

I would consider myself to be pretty fit. I lift weights, run and do Body Pump and am pretty lean already, although I don’t know my exact body fat right now.  I’d really like to make this the year that I get flat abs, but I still have some belly fat I’d like to make go away. Nothing major, just a little “pooch” and a smidge more side and back fat than I want …. we’re not talking a muffin top or anything like that though.

My girlfriend suggested that I try drinking more whey protein to lose weight. Her boyfriend is in really good shape and drinks a ton of protein shakes and she seems to believe that’s why he is so lean. She’s in great shape herself and uses a lot of whey protein, so I’m inclined to believe her.

What are your thoughts here?  I really just want to lose those last couple of lbs of belly fat. I’m fairly tall and already pretty toned, it’s just my damn belly that I want to tighten up. Can whey protein help with this?

By the way, I already drink whey protein powder once a day in soy milk, usually in the morning and sometimes after I work out.  Thanks for your time. Alicia (Long Island, NY)

Alicia, this question pops up a lot on discussion boards and in places like Yahoo Answers and Yedda.  So you’re not the only one who is trying to figure out if there is really a connection between whey protein and weight loss.  I probably see a variation on your question at least 2-3 times a week.

There are definitely a lot of “opinions” floating around out there around whey protein for weight loss. There’s some truth to them, but they are also tied up in a lot of myths, as well. So the trick is to understand exactly what whey protein is (and isn’t) so you can come to your own conclusions based on the facts.

What Is Whey Protein?

Whey is just a form of protein that is naturally-present in diary products like skim milk, cottage cheese, yogurt, etc. If you drink a glass of milk, you are already consuming some whey proteins. The whey protein that you are talking about is in a powdered form. Basically, the manufacturer takes liquid whey and “dries it”, making whey protein powder – a form of whey that is portable and easy to reconstitute.

So What Does Whey Protein Do For A Person?

The main benefit to whey protein is that it is easily and quickly digested by the body.

The body is also able to quickly utilize most of the amino acids in whey protein to help with tissue repair and recovery after exercise.  The protein in whey has a high biological value (BV), meaning it’s easily absorbed by the body. Unlike other proteins, like casein (another form of protein in milk), the speed at which whey protein is digested makes it an ideal source of protein immediately following workouts when your body needs amino acids quickly to aid with recovery.

Whey protein, especially whey protein isolate (an even more concentrated form of whey protein vs. whey protein concentrate), is also very low in fat and carbohydrates. This is because the refinement process used to create whey protein powder removes nearly all of the fat and sugars in the liquid, leaving a final product that is almost 100% protein by volume.  So this makes whey protein popular among dieters and people who are trying to limit carbohydrates or fat in their diet.

Whey protein has other properties that may have health benefits, including the presence of certain biologically active compounds that may improve immunity and even stave off muscle wasting. However, the main reason people consume whey protein is to encourage lean muscle growth and sometimes as a meal replacement.

Using Whey Protein For Weight Loss

Okay, now that you know what whey protein is, let’s tackle your question about whey protein and weight loss.

First, it’s important to understand that there is nothing particularly magical about whey protein that will directly cause you to melt off that last pound or two of belly fat and get abs like Jessica Biel. Whey protein is not an anabolic steroid — it’s a food.

In fact, the goal of drinking whey protein is usually to add weight (in the form of additional muscle), not to lose it. 

That said, because your real goal here isn’t to lose scale weight, but to lose body fat and change your body fat percentage to favor lean tissue, including some additional whey protein in your diet could help you become leaner overall … and yes, that would probably include losing some belly fat.

What is Whey Protein Powder and Do I Need It? | Diet and Nutrition

Find Out How Whey Protein Powder Went from Dairy Underdog to Nutritional Superstar

Whey protein seems to be everywhere. 

One of the top selling (and most heavily-marketed) nutritional and sports supplements on the market today, whey protein turns up as an ingredient in everything from smoothies to nutrition bars to high-protein cereals.  Personal trainers often include whey as part of their clients’ diet plan, smoothie bars offer it mixed with ice and fruit, and aspiring bodybuilders and soccer moms alike seem to have found a permanent place for a tub of whey protein powder in their pantries.

But what exactly is whey protein powder? Where does this stuff come from? And do you really need it?

A Brief History of Whey Protein

Whey is a natural by-product of the cheese-making process. Milk contains two primary proteins: casein and whey.  Whey composes about 20% of milk proteins, and casein comprises the remaining 80%. So when you drink a glass of milk, you are consuming both casein proteins and whey proteins.

During the cheese-making process, an enzyme called rennet is added to milk to curdle it. The curds are used to make cheese, and the remaining liquid is whey.

Historically, this liquid was considered more-or-less useless. Indeed, the dairy industry had so much excess whey that they struggled with disposing of the surplus. Some of it found its way into swine or cattle feed, where it appeared to produce larger, meatier cows or pigs, but a great deal of it also ended up in the landfill.

Which was really a shame, because the cattle farmers were on to something. It turns out that whey is extremely rich is three milk proteins – specifically beta-lactoglobulin (~65%), alpha-lactalbumin (~25%), and serum albumin (~8%) — which are more easily digested by the body than any other protein, including the holy grail of protein, eggs.

There was just one problem: Whey in its naturally occurring form is a sloppy, liquid mess.  It also has very little flavor. Trying to sell the world on a great protein source that has to be refrigerated and doesn’t have much taste would challenge even the best marketer.

Enter modern technology.  Scientists figured out a way (no pun intended) to “dry” and powder-ize whey, while still maintaining it’s basic nutritional profile.  The result was whey powder, which could be reconstituted in liquids while still preserving its protein values.

The rest, as they say, is history.
