These days, protein shakes aren’t bought by just body builders – they’re so popular that you can readily buy a 400 g tub at your local supermarket or service station. And with tempting claims such as ‘Facilitates muscle toning’, ‘Contains transformation-making protein’ and ‘Tastes incredible, mixes easily’, why wouldn’t you grab one? But protein shakes aren’t the magic answer to all your weight-loss woes. Let’s take a look at what you get for your money.
Guest post by dietitian Zoe Wilson APD
From body builders to football players, many athletes use protein powders to help them build muscle mass. People who are trying to gain weight or who are on a liquid diet (think mouth surgery or a broken jaw) may need to take protein in liquid form, too. But these people are in the minority.
If you just want to feel full and beat the 3pm munchies, however, there are better, healthier and cheaper alternatives. And if you think it’s a weight-loss solution, think again! Protein shakes aren’t the solution to losing weight that many would have you believe.
Most protein shakes consist of protein from soy or dairy (whey or casein) in powdered form, either with or without carbohydrates and other performance-enhancing ingredients such as carnitine, ‘fat metabolisers’, vitamins and minerals.
When you mix these powders with water or milk, they turn into a milkshake- or smoothie-type drink.
When you look at the ingredients list, however, it becomes clear that these shakes are NOT simply powdered protein. There is a host of other ingredients, including additives such as gums, thickeners, sweeteners, flavours and indigestible fibre, some of which can commonly cause symptoms such as bloating, wind, nausea and diarrhoea. You’ll be surprised at just how many ‘extras’ these powders contain.
For instance, a typical chocolate-flavoured powder contains these ingredients:
We compared the protein, kilojoules and cost of a typical protein shake, made using 45 g protein powder and 1 cup milk or water, to two eggs or a glass of skim milk.
|
2 eggs |
250 ml skim milk |
1 serve protein powder made with 250 ml skim milk |
1 serve protein powder made with 250 ml water |
Energy (kJ) |
580 |
370 |
1,000 |
600 |
Protein |
13 |
9 |
30 |
25 |
Cost per serve |
$0.90 |
$1.00 |
$4.10 |
$3.60 |
At 25–30 g protein per serve, the protein shakes had 1.5–3 times times more protein than the two eggs or skim milk.
Sounds good, right? But just wait a second before you buy a tub. The protein shakes were also higher in kilojoules than eggs or skim milk. A typical protein shake made with skim milk has about 1,000 kJ, which is almost double the 600 kJ recommended for a snack, and almost three times the kilojoules of a glass of plain old-fashioned skim milk. It’s no between-meal snack.
The protein shakes were more expensive, too. Per serve, they were up to four times pricier than eggs or skim milk. There are better, healthier and more affordable ways for you to get your protein.
Increasing your protein intake modestly can help you lose weight. Studies have shown that a higher-protein diet that includes low-Glycaemic Index (GI) carbs is one of the most successful diets for weight loss because it helps to keep hunger at bay and is easy to follow in the long term.
The main problem with these powders is the kilojoules. If you’re adding protein powders as extra snacks throughout the day, and don’t adjust and eat less at your next meal, then you’ll be adding excess kilojoules that will be stored as fat. Exactly the opposite of what you’re trying to achieve!
Protein powders are convenient, but food can be too. It’s easy to increase the amount of protein in your diet through food alone. For example, make sure you always include some protein at each meal – eggs or yoghurt at breakfast, chicken or tuna in your wrap at lunch and meat in a stir-fry at dinner. Also choose protein-containing snacks such as a handful of nuts, small tub of yoghurt or hard-boiled egg.
To shake or not to shake? For the average person, it’s fine to increase your protein intake modestly if you’re looking to lose weight, but there’s no need to overdo it. It’s really easy to get enough protein through diet alone. Instead of paying top dollar for protein shakes, why not look to foods such as dairy, eggs, fish or meat? These will keep you full and help with muscle-building and weight loss.
By choosing whole foods over protein powders, you know you’re eating something minimally processed that’s packed with other great nutrients. You’ll also cut out any artificial ingredients – and all for a fraction of the cost. Don’t be fooled by those claims sprawled across the packet and always remember, if it sounds too good to be true, then it probably is. No powder beats a healthy diet for health in the long run.

What’s in your favourite tomato pasta sauce, and how much of it? Here are the most popular sauces reviewed for your reading pleasure.
I’ve rated nine of the most popular tomato pasta sauces in terms of their nutrition, ingredient lists and jar size. You’ll find many of these in your local supermarket. The sauces are ranked:
When you’re next out shopping, run your eyes down the per 100 g column and look for products containing less than 400 mg sodium AND less than 5 g fat (which equals 5% fat). Most of the brands are below these levels. I like Barilla, Sacla, Leggo’s, La Gina and Mutti – but that’s just me!

Want something to drink before dinner? Something that’s LOWER in alcohol than wine? To match his beer? Then look no further than Bundaberg’s low-sugar alcoholic ginger beer.
You can drink Bundaberg low-sugar ginger beer straight from the can, or pour it into a long glass over ice with a slice of lime.

When I was first asked to write this review, I thought, Not another tracker.
After all, there have been several in recent years, such as My Fitness Pal and Everyday Diet Diary. But this one is different. It works by using your Everyday Rewards card AND your shop at Woolworths.

Intermittent fasting vs daily calorie restriction
3 May 2023 by, Catherine Saxelby
As you probably know already, intermittent fasting (IF) has gained favour as an alternative regimen to daily caloric restriction (DCR). Fasting is shown to extend the lifespan of rats, and has been associated with metabolic benefits in humans, yet the results so far have been inconsistent. So, which regimen is best for healthy weight loss?
15 March 2023 by, Catherine Saxelby
What sort of a diet should you follow to lose that excess weight? These days, it’s pretty confusing with high-protein Keto advocates clashing with plant-protein followers … as well as intermittent fasters, juice-only dieters, no-carb dieters and no-animal (aka plant-based) dieters. Plus all the ads for anti-hunger supplements, meal-replacement shakes and home-delivered meals, more of which somehow appear every day. So, what sort of diet should YOU follow to lose that excess?

How to lose weight WITHOUT going on a diet
14 October 2020 by, Catherine Saxelby
The word 'diet' is a turn-off for most people. It sounds hard, unpleasant and unpalatable. Losing weight doesn’t have to be hard AND it doesn’t have mean sticking to a 'diet'. You can forget Paleo, Keto, Vegan and Raw, Gluten-free and Intermittent Fasting. To lose weight, you don’t have to follow any specific diet. What you need is simple, healthy, nutritious food and a few tips and tricks.
What IS a healthy balanced diet for weight loss?
16 September 2020 by, Catherine Saxelby
Healthy weight loss happens when you lose weight slowly and steadily (around 1 kg or 2 pounds weight loss a week). Your goal is to lose weight while still getting your essential nutrients but from smaller portions. You certainly don’t want to be tired with no energy! That’s why you need regular healthy meals and snacks on hand to ensure your vitamins, minerals, omega-3s and fibre needs can be easily met. There is a new range of healthy weight loss meals available and it’s one that I’d like to recommend. With these ready meals, you’ll say goodbye to meal planning, shopping, meal preparation and cooking.

“This year, I'm going to lose weight!”, or “This year I’m opting for a healthier lifestyle!” Is your 2020 New Year's resolution something like one of these? If so, how is it going to happen?
Q. What's the difference between Diet Coke and Coke Zero?
12 September 2013 by, Catherine Saxelby
A. At first glance, Diet Coke and Coke Zero appear to be identical. Both contain no kilojoules (Calories) and no sugar. Both are artificially sweetened with (the same amount) of aspartame and acesulfame K and therefore have the same ‘sweetness’.
How to convert sodium to salt (and salt to sodium)
6 August 2010 by, Catherine Saxelby
As a nutritionist, my aim is to help busy women eat healthily. One of the ways to do this is to follow the general nutrition advice to reduce the salt in your diet. So, how can you do this when what you’ll see on a food label and on any recommended daily intakes is sodium?
7 types of sugar - which is healthier?
11 December 2013 by, Catherine Saxelby
Last week on the radio, the announcer asked me if there was a 'good' sugar – one that would satisfy her sweet tooth but that was 'healthier' than regular white sugar. She figured if there were 'good' carbs and 'bad' carbs there must be some sugars that would get the nod of approval from nutritionists.
Eat to beat gastro and diarrhoea
12 October 2012 by, Catherine Saxelby
A clear fluid diet is the best form of treatment for gastro and tummy upsets. It is the "lightest" type of diet, designed to place as little strain as possible on the digestive tract. It is NOT nutritionally adequate and should be followed only for a strictly limited time e.g. two or three days but no more than a week.
Nutella. The full (correct) list of ingredients
12 April 2011 by, Catherine Saxelby
Have you ever tried to find the exact list of ingredients for Nutella online? The identical one that appears on its label - in descending order from the first (largest ingredient by weight) to the last ingredient, as required by law? Well, you won’t find it! Here’s the hoop-la I went through to discover exactly what the ingredients in Nutella are and why Nutella is not good for your kids.
Sugar - why quitting sugar guarantees you'll lose weight
6 May 2013 by, Catherine Saxelby
Sugar. It's been labelled "deadly", "addictive", "toxic", "sweet poison" and blamed for the rise in global obesity in recent years." Get rid of the white toxin from your diet and you'll free up your body to drop those excess kilos" (or so say anti-sugar campaigners Sarah Wilson, David Gillespie and Robert Lustig). Here are the three real reasons why I believe quitting sugar helps you lose weight.
What does 8,700 kilojoules look like?
14 August 2012 by, Catherine Saxelby
8,700 is a magic number in nutrition. It’s the number of kilojoules (kJ) that is the “average” intake for adults in Australia, if the surveys are correct.
It’s widely used as a benchmark figure and as the basis of food labels such as the Percent Daily Intake values.
Recently kilojoules have appeared on fast food menu boards and they use 8,700 as the yardstick to assess their foods against. Here's my take on it.

This is a kind of pavlova topped with fruit, but the base is made from ricotta, rather than egg whites and sugar.

This is an Asian-influenced salad that’s perfect to serve as a side salad at a BBQ or with a fillet of fish.

This banana loaf is half bread and half cake. Hence I've called it "cread" which is halfway! It’s dense and delicious without being super-sweet or oily. It can be enjoyed fresh, toasted or sliced and frozen into portions to enjoy later.

This quick and easy dessert is ready in minutes. And there are NO leftovers to tempt you later!

Squash-ed spaghetti bolognaise
3 August 2022 by, Guest post
This is an excellent make-and-freeze recipe, so weeknight meals become more manageable. I know of no better way of ‘hiding’ veggies than in a Bol sauce – somehow mince with a few veggies like pumpkin or zucchini is a match-made-in-heaven.
