Weight loss shakes also known as meal replacement shakes were originally designed to help people easily absorb nutrients. They are now intended to offer a convenient alternative to traditional weight loss diets while providing nutrition equivalent to a full meal.

Shakes for weight loss promise rapid results. Their formulas generally consist of high protein (milk and soy-based powders), coupled with low carbohydrates, and supported by vitamins and minerals.

Meal replacement shakes have become increasingly popular over recent years because they are less restrictive than the diet programs. They can help cut calories without making you completely forgo the foods you enjoy.

What Is the Best Weight Loss Shake?

There are so many weight loss products on the market that it is often difficult to choose the best healthy meal replacement. To help you choose and find the best weight loss shake, we compared nutritional values, flavors, and value for money.

Product quality has the most influence on our rankings because we want it to be a real meal replacement and not just a powder full of sugar.

We gave more points to products that have natural ingredients while being low in artificial flavours and preservatives.

One of our ranking guidelines is that products should have as few ingredients as possible. In general, we believe that if products contain a never ending list of ingredients, the brand is usually trying to cut corners and obfuscate the low quality.

We prefer products that are a blend of good fats, carbs, and proteins because these are essential to a balanced human diet.

And we took into account the value for money. Changing your diet is a long term commitment and should fit your budget so you can sustain it.

Do Meal Replacement Shakes Work?

A meal replacement shake is not a magic solution. They could be a starting point that helps you get on the right track to losing weight. Since they are so convenient you may be more likely to stick to the plan and keep going once you get the taste of losing fat.

After this initial stage of using shakes, long term weight loss will likely require a lifestyle adjustment. This includes a healthy diet and a regular exercise program.

Another thing to keep in mind is that there are meal replacement shakes packed with corn syrup, preservatives, and other counterproductive ingredients. These are often cheaper but best to avoid.

The best meal replacement shakes come with vitamins and minerals that contain essential nutrients, protein, and are low in carbs.

Are Aldi Shakes Good for Weight Loss?

People seem to love Aldi products and shakes are no exception. While they are generally less expensive than other weight loss shakes, Aldi shakes seem to offer value without compromising on the quality.

Aldi shakes won the Canstar Blue Award for two years in a row (2019 & 2018) with these being based on customer satisfaction.

There are also many examples online of people losing significant amounts of weight by just replacing one meal per day with an Aldi shake [1].

Based on this, they may be worth a try.

What to Look for When Buying a Meal Replacement Shake?

You should know what to look for when purchasing weight loss shakes. There are so many brands in the weight loss market that it can get overwhelming when deciding what to purchase.

If purchasing a weight loss product from a local Australian business, the main thing you should look for are products labelled “formulated meal replacement”. These products meet the requirements of Australia New Zealand Food Standards Code [2].

You can also figure out quickly whether a meal replacement shake is good or bad by simply reading the label and knowing what the ingredients mean.

Here is a table that can simplify the process for you:

What to look for What to avoid
12–25g of protein per servingHigh calorie count
(more than 400 calories per serving)
20+ vitamins and mineralsNo fibre
Healthy fats (10–13 grams)Artificial flavors
Convenient packaging and preparationAdded sugar

Another way to quickly narrow down the product range is to ask yourself what dietary requirements you have. Are you looking for gluten free, natural, organic, or vegan friendly options?

How Much Weight Can You Lose With Meal Replacement Shakes?

There are many factors that can influence how much weight you can lose including the quality of shakes, your current weight, and individual circumstances, and your level of commitment to make changes to your lifestyle that last.

It also can make a difference whether you replace one, two meals a day or even three (more doesn’t mean better results in the long run and it depends on the shake).

Potential Benefits

Burn Fat Fast

Losing weight comes down to taking in fewer calories than you expend. You can do this by eating less, hitting the gym, or going for a run. In general and for the majority of people the best way to lose weight is a combination of physical activity and a healthy diet.

For those that need to lose weight quickly and in the short term, meal replacement shakes are a good option because they can substantially reduce calorie intake while giving your body the right nutrients to function properly.

Provide Nutrients

Meal replacement shakes are intended to provide a complete assortment of nutrients you are meant to consume in a meal.

The best weight loss shakes contain protein, fibre, and wholesome ingredients.

This should enable you to meet your nutrient needs while cutting back on calories.

Avoid Unhealthy Meals

As much as weight loss shakes can help you lose weight by giving your body the right nutrients, they also play an important role in helping you avoid low quality foods.

One of the biggest reasons people cite for not eating healthy is the lack of time to prepare meals.

When you are stressed and in a hurry, busy with work and family, it’s much easier to grab fast food.

The processed foods do not have the right nutrients and are full of sugar, refined carbs, and artificial ingredients, which make you gain weight.

Meal replacement shakes solve this problem by giving you a healthy, convenient alternative to processed foods and fast food.

Potential Side Effects

Dieting, whether in the form of a meal replacement shake or traditional diets, is part of life for many people. However, most experts would suggest that focus on health is the only way to lose fat and keep it off [3].

If you experience any side effects, you should stop using weight loss shakes immediately. Also, before starting any diet or regular meal replacement program, it is a good practice to consult with your GP or dietitian and make them aware of your plans and progress.

Not Satiating

Meal replacement shakes may also not be as satisfying as solid food. The value proposition of diet shakes is that they are an easy and convenient way to help people lose fat, but they may not be satisfying. Liquid food may not curb hunger as much as solid food and that’s one of the reasons people end up overeating and even gaining more weight than before.

Poor Ingredients

There are many weight loss shakes made with wholesome ingredients like those best ranked above.

Unfortunately, there are some on the market that contain added sugars, corn syrup, vegetable oils, artificial flavors, and chemical preservatives. These are easily avoided by reading the label.

Look for high protein shakes, rich in fibre, and common ingredients found in a healthy diet. Also, they shouldn’t contain more than a few grams of sugar (preferably sugar free).

Expensive

Meal replacement shakes can get expensive if you end up using them long-term. You need to take into account your personal financial situation before committing.

However, the benefits of losing weight will likely make the cost worth it.

The Bottom Line

To lose weight long term, you need to make lifestyle changes and have a better choice of diet on a daily basis.

Weight loss shakes might be able to help you get some results short term that will hopefully provide you with an incentive you need to keep going once you start seeing the results.
