Plant-Based Meal Replacements

Why Should I Add a Plant-Based Meal Replacement to My Diet?

Plant-based meal replacements are dietary supplements made entirely from plant-based ingredients.

They are intended to replace the nutritional value of a healthy, balanced meal.

Some meal replacements are ready-to-drink whereas others are in powder form and must be mixed with liquid.

The nice thing about a plant-based meal replacement powder is that it can also be added to smoothies, oatmeal, and other recipes for extra calories and nutrients.

This is ideal for someone who does not like meal replacement shakes, or who wants a versatile way to meet his or her dietary needs.

Here is a summary of the benefits of adding a plant-based meal replacement to your diet:

• Convenience: Meal replacement shakes are quick and easy to prepare, making them a great option for busy individuals who might not have the time to prepare a full meal.
• Nutrition Support: Adding a meal replacement shake to your diet is an easy way to increase your calorie and nutrient intake, making it a great option for someone who struggles to eat enough due to dietary or lifestyle restrictions.
• Weight Management: Meal replacement shakes can help with weight management by providing controlled portions and calorie intake.

Keep in mind that relying on meal replacement shakes too often can cause you to miss out on the benefits of solid foods.

This is why it is important to only use meal replacements in moderation.

Are Plant-Based Meal Replacements Good for Building Muscle?

Yes, plant-based meal replacements can help with muscle building and recovery, especially when combined with weight lifting.

As long as you are eating a balanced diet – getting your protein from a variety of sources – any type of meal replacement can help you achieve your body composition goals.

Although you might have to eat more plant proteins than animal proteins to see the same results, research shows that high-protein plant-based diets support comparable muscle adaptations to omnivorous diets during resistance training (J Nutr, 2023).

How Do I Make Plant-Based Meal Replacement Shakes?

Ready-to-drink meal replacement shakes require no preparation whatsoever – you can drink them straight from the container.

They tend to be less healthy than homemade meal replacement shakes, however, because in order to create a shelf-stable product, ready-to-drink shake manufacturers rely on a cocktail of ultra-processed food additives.

So, if I were you, I would make my own plant-based meal replacement shakes with meal replacement powder.

Although slightly less convenient, making a homemade meal replacement shake is still easy!

All you need to do is mix meal replacement powder with water or your milk of choice.

If you have a blender, you can also add ice, fresh or frozen fruit, and nut butter for extra flavor and nutrients.

What Are the Best Plant-Based Meal Replacement Shakes?

Not all high plant-based meal replacements are created equal.

Many contain ingredients known to cause painful side effects and even long-term health problems.

Among these ingredients are food additives and protein concentrates and isolates.

🚫 Avoid Food Additives

Regularly eating emulsifiers, thickeners, artificial sweeteners, and other ultra-processed additives can alter the composition and function of your gut microbiome (North Clin Istanb, 2020).

These shifts, known gut dysbiosis, contribute to a wide range of chronic diseases, including diabetes and even certain cancers (J Exp Med, 2019).

Gut dysbiosis is so problematic because it causes a cascade of problems, including intestinal permeability, systemic inflammation, impaired nutrient absorption, and reduced short-chain fatty acid (SCFA) production.

⚠️ Here is a list of the most common food additives in meal replacements:

• acacia fiber
• acacia gum
• acesulfame potassium
• artificial flavors
• ascorbic acid
• aspartame
• calcium carbonate
• carrageenan
• cellulose gum
• dextrin
• dicalcium phosphate
• dipotassium phosphate
• erythritol
• gellan gum
• guar gum
• gum arabic
• inulin
• locust bean gum
• maltitol
• maltodextrin
• mono- and diglycerides
• ‘natural’ flavors
• rice bran extract
• rice dextrin
• rice hulls
• rosemary extract
• silica
• silicon dioxide
• sodium alginate
• soluble corn fiber
• sorbitol
• soy lecithin
• sucralose
• sunflower lecithin
• tocopherols
• tricalcium phosphate
• xanthan gum
• xylitol
• zinc oxide

As a rule of thumb, if you could not find an ingredient in nature or make it at home, it is a food additive.

🚫 Avoid Protein Concentrates and Isolates

You should also consider avoiding protein concentrates and isolates.

Most meal replacements are made from one or both of these protein sources, which have been mechanically and/or chemically stripped of everything but the protein.

This includes the enzymes, fiber, and other natural digestive aids that help you break them down.

You therefore do not digest them in the same way that you do whole foods, which can affect your gut health.

In fact, studies show that regularly eating protein concentrates and isolates can disrupt your gut microbiome and cause the formation of toxic byproducts in your gut (Nutrients, 2018; Mol Nutr Food Res, 2024).

So instead of ultra-processed protein concentrates or isolates, look for whole food protein sources like egg whites and almonds.

They are easier to digest and absorb.

When Should I Add a Plant-Based Meal Replacement Shake to My Diet?

Plant-based meal replacements can be used when convenience, nutrition, and dietary preferences align.

Here are a few scenarios where they might be particularly useful:

• Busy days: For individuals with hectic schedules, a meal replacement shake can provide a quick and nutritious meal option. It can also be a great option during travel when access to healthy food options is limited.
• Post-workout recovery: After a workout, a plant-based meal replacement shake can provide proteins and carbohydrates to aid muscle recovery and replenish energy stores.
• Filling nutritional gaps: Meal replacements can be used to fill nutritional gaps. This is especially helpful for individuals with dietary restrictions or specific nutrient deficiencies.
• Prevent meal skipping: If you tend to skip meals due to a lack of time or appetite, having a meal replacement shake handy can help you build healthy eating habits
• Medical support: For individuals with digestive issues or medical conditions that make consuming solid food difficult, a liquid meal can be a lifesaver.

Note that in all these situations, it is important to choose a plant-based meal replacement made with a short list of simple ingredients suited to your specific dietary needs.

How Many Plant-Based Meal Replacement Shakes Should I Drink Per Day?

The number of plant-based meal replacement shakes you should drink per day depends on several factors, including your nutritional needs, health goals, and overall diet.

General recommendation:

• 1-2 shakes per day: Most dietitians and nutritionists recommend replacing one to two meals per day with meal replacement shakes, ensuring that you still consume at least one normal meal.

Considerations for specific goals:

• Weight loss: If your goal is weight loss, replacing one or two meals per day with a low-calorie, high-protein plant-based meal replacement shake can help.
• Weight gain: If your goal is weight gain, adding one to two meal replacements to your current diet can help.

Other considerations:

• Medical conditions: People with medical conditions or dietary restrictions should consult with a healthcare professional before significantly changing their diet or using meal replacements regularly.

In summary, while one to two plant-based meal replacement shakes per day is generally recommended, individual needs can vary.

Consult with a healthcare professional for personalized advice.
