Meal Replacements Without Artificial Sweeteners

Are Artificial Sweeteners Bad for You?

Artificial sweeteners, to put it simply, are synthetic chemicals added to foods, beverages, and supplements to make them sweet.

They can be found in most meal replacements, and are so popular because only a pinch can be used to achieve the same amount of sweetness as several tablespoons of sugar.

This allows manufacturers to reduce both calorie and sugar content.

The most common artificial sweeteners are sucralose and acesulfame potassium.

In case you were wondering, xylitol, erythritol, sorbitol, and mannitol are sugar alcohols, not artificial sweeteners.

This does not necessarily mean that they are better for you, however.

Despite their benefits, artificial sweeteners are not good for you (J Pharmacol Pharmacother, 2011).

First of all, several studies have shown that artificial sweeteners can increase cravings toward sugary and sweet foods, leading to binging and feelings of withdrawal (Yale J Biol Med, 2010).

If you are trying to lose weight, you are probably just better off just eating sugar.

Research has also associated artificial sweeteners with a higher risk of glucose intolerance, which is a precursor for pre-diabetes and diabetes (Nature, 2014).

And worst of all, regularly eating artificial sweeteners can alter the composition of your microbiome (Adv Nutr, 2019).

This can lead to gut dysbiosis, or an imbalance in gut microbiota, which is a leading driver of inflammation and linked to the development of many chronic diseases (Microorganisms, 2022; Nat Rev Nephrol, 2023; J Exp Med, 2019).

Why Should I Consider Monk Fruit?

Instead of using artificial sweeteners or sugar alcohols, we sweeten our Meal Replacements with monk fruit.

Monk fruit, also known as luo han guo, is a melon-like fruit native to Southeast Asia.

Its intense sweetness, which is about 200 times that of sugar, comes from non-caloric compounds called mogrosides.

Firstly, monk fruit sweetener is the most natural sugar substitute on the market.

It is made by removing the seeds and skin of the fruit, crushing the flesh, and collecting the juice, which is then dried into a powder.

Monk fruit is also sweet like sugar.

Artificial sweeteners, on the contrary, activate bitter taste receptors in addition to sweet taste receptors, which gives them an unpleasant bitter aftertaste (J Neurosci, 2004).

It is worth adding that monk fruit has been safely used in Asian cuisine for centuries with no known side effects, even when consumed in large quantities.

Moreover, small randomized trials have shown that monk fruit does not negatively impact blood sugar or insulin levels (Eur J Clin Nutr, 2017).

What About Stevia?

If a company makes meal replacement shakes without artificial sweeteners, chances are high that it uses stevia.

Stevia, although celebrated by many as a natural alternative to artificial sweeteners, might not be as natural as you think.

Stevia is extracted from the stevia rebaudiana plant using chemicals like ethanol and methyl alcohol.

This, some argue, makes it no more natural than the artificial sweeteners that it seeks to replace.

In fact, a recent class action lawsuit filed in California reached a $6.1 million settlement because it was ruled that the company in question falsely labeled and advertised its stevia sweeteners as “natural.”

It is worth adding that stevia, like artificial sweeteners, activates bitter taste receptors, giving it an unpleasant aftertaste (J Neurosci, 2004).
