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 Are MUFAs? | Ask the Fitness Nerd

What’s a MUFA? The Fitness Nerd explains what this funny acronym means and why MUFAs are suddenly the rage among dieters.

Dear Fitness Nerd:

What are MUFAs? I keep hearing people talk about them, but I still haven’t quite figured out what they are. I know they are a type of fat, but I thought fats were unhealthy and should be avoided. Are they a supplement of some type like CLA? - Kayla R, (West Hollywood, CA)

MUFAs are an acronym for a “monounsaturated fatty acids” — a class of healthy fats found in foods like nuts and seeds, avocados, olives and certain vegetable oils. MUFAs are not typically taken as a supplement (as Conjugated linoleic acid or CLA often is), since they are plentiful in foods. 

MUFAs have gotten a lot of attention recently for three reasons:

1. MUFAs may help you lose weight.

There is some evidence that people who regularly consume MUFAs have lower body fat levels and are more successful at dropping body fat and weight than people who are on low-fat, carbohydrate rich diets.

This research flies in the face of  the conventional-wisdom that drove the low-fat craze of the 80s and 90s, which advised people to reduce their fat consumption as much as possible in order to lose weight, lower cholesterol and reduce the risk of stroke, high-blood pressure and heart disease. The latest research actually suggests that diets which are higher in healthy fats like MUFAs may be more effective at weight-control than low-fat diets.

2. MUFAs may reduce the risk of disease.

A growing body of research shows that MUFAs may not only help people lose fat, but that they also have protective properties that may lower the risk of developing certain diseases, including Type II Diabetes, heart disease, stroke and possibly certain types of cancers. MUFAs are also part of The Portfolio Diet, which is an approach to eating that combines MUFAs with other cholesterol-lowering foods like soy, plant sterols and soluble fiber from things like oatmeal and may reduce blood cholesterol-levels as effectively as prescription statin drugs.

Dietary Fat: Five Myths About Fat | Diet Tips

Think eating less fat will make you thinner? Not necessarily. Answer Fitness debunks the five most common myths people have around dietary fat.

Navigating the sometimes contradictory research and information around dietary fat can make a person’s head spin. Should I eat more fat? Less fat? A different kind of fat? Here are the five most common myths around dietary fat:

Myth #1: Eating more fat makes you fatter

Not true.

Eating more calories than you burn makes you gain fat.

Whether those excess calories come from protein, carbohydrates or dietary fat, any calories that you eat above your daily energy requirements will get stored away as body fat. 

The issue with dietary fat is that it’s extremely calorie dense, meaning that it contains more calories per gram than other macro-nutrients like protein or carbohydrates. This means that gram-for-gram, foods with a higher fat content contain more calories (9 calories per gram of fat versus 4 calories per gram for carbohydrates and protein.)

So if you aren’t careful, you can end up eating more calories in foods with higher fat content, even though you are eating the same amount of food.
