Latest Study on Meal Replacement Shakes and Weight Loss

Meal replacement shakes have had mixed opinions over the years. Many people swear by them, whereas other people… not so much.

If you don’t already know (if you happen to stumble upon this blog post), we developed a meal replacement shake called The Slim Mama Shake. So when this new study popped up on my instagram (shout out to I had to have a read and share the news.

What was the study?

The study was aimed to figure out if meal replacement shakes are more effective for weight loss compared to food-based calorie restricted diets. And if so, what factors determine the success of the strategy.

References for this study can be found below.

I should also mention this study is a meta-analysis, this is the gold standard of study types. This means they got a whole bunch of studies on the topic, analysed them, then make a conclusion with the data.

As wikipedia adequately put - “A meta-analysis is a statistical analysis that combines the results of multiple scientific studies. Meta-analyses can be performed when there are multiple scientific studies addressing the same question, with each individual study reporting measurements that are expected to have some degree of error. The aim then is to use approaches from statistics to derive a pooled estimate closest to the unknown common truth based on how this error is perceived.” -

I won’t go into the boring deets, and I’ll skip straight to the juicy stuff! The answer!

They found that meal replacement diets had a better advantage than food-based diets for weight loss. A diet with at least 30% or higher of meal replacement shakes (e.g 2 or more meals as meal replacements) was associated with greater weight loss.

They hypothesised that replacing a food meal with meal replacement might just be a convenient way of reducing intake while taking out the complexity of a diet. Thus increasing adherence, which then increases weight loss outcomes. 

They also noted that the advantage of meal replacements appear to extend to up to one year, so it constitutes a 'viable' treatment option.

They noted that they didn’t conclude whether meal replacements also help with other important health outcomes such as cardiometabolic risk factors or other obesity related diseases. But it can be assumed that a reduction in weight will also positively affect these risk factors.

In conclusion, our meal replacement shake is great for weight loss and you should totally purchase a pouch right now!
