These shakes typically offer a blend of macronutrients, such as protein, carbohydrates, and fats, along with several micronutrients, vitamins, and minerals.

Meal Replacements and Allergens

One of the most underrated aspects of meal replacement shakes is that contain very few allergens, and that there are even shakes free of allergens.

Amongst the most common features, most meal shakes are gluten-free, thus ideal for coeliacs.

You can also opt for dairy-free meal replacement shakes that contain no lactose and often no animal-derived products.

Other common allergens that are not present are soy, eggs, nuts to name a few.

Plant-Based Meal Replacement Shakes Exist

Similarly, the majority of meal replacement shakes are fully plant-based.

This means that they are a vegan-friendly option to consume on the go that will provide you with 20g of protein (or more) per serving, and vitamin B12 and omega-3 fatty acids that you might be lacking in your diet otherwise.

Thus, they can complement any vegan diet.

A study carried in Frontiers in Nutrition Journey (funded by Huel) 20 participants consumed Huel meal shakes for four weeks mixed with just water. After the study, most participants showed improvements in blood markers (LDL levels, iron, haemoglobin, vitaminB 12…) and their BMI dropped.

Another study focused on weight loss also found that calorie restricted diet paired with meal replacement intake led to weight loss as well as improvements in body composition and metabolic parameters.

Similar results have been achieved in oterh studies with 90 adults (2010), and more recent 2021 study when compared it with a “normal food” diet.

Here are some user testimonials:

I’m doing a keto diet, 75% of the meals is KetoGenesis, a soylent. It is AMAZING. The first 3 weeks or so were difficult as I had to adapt to keto and soylent simultaneously, but since then, I feel great. I fall asleep fast and sleep deep; energy levels throughout the day are high and constant (no afternoon dip); I lose fat; exercise performance remains unaffected; I save a hour or more every day by not having to eat and cook. I don’t see myself ever going back to a classic solid diet


For the past year, my diet has been 95% plenny shake.

My diet before was pretty sorry. Reheated frozen food or typical pantry stuff like cereal. I also ate a lot of snacks and candy, and I drank soda. I rarely had fruits or veggies. The only cooking I would do was scrambled eggs occasionally.

All of that is done now. I don’t even buy that stuff anymore. I drink the shakes and in between meals I drink water. Mentally and physically I feel better than I ever have.

Here in Latestfuels, we’ve been consuming meal replacement shakes for over 5 years now.

Enaut editor of Latestfuels

When I, Enaut, started consuming meal replacement shakes, I didn’t think they were going to become such an integral part of my life.

Initially, there were just there to help me as a student to eat healthy on the go. I liked cooking and eating too much to use them regularly.

However, at some point, I realised that I loved the convenience, having easy access to protein, and being able to eat what I needed where I needed.

Since, I’ve been regularly having meal replacement shakes (mostly for breakfast). My health has never been better. My bloodwork has always been great, and I haven’t been seriously ill.

I pair my meal replacement shakes with exercise, and a balanced diet, but I know that without them I would be eating worse. In fact, in the rare occasions that I have stopped, I have had constipation issues.

Conclusion – Are Meal Replacements Healthy? Yes

After exploring the question of whether meal replacement shakes are healthy and examining various aspects related to their usage, it’s clear that incorporating these products can provide you with clear health benefits.

However, it is important to pick a healthy meal replacement shake from a reputable brand.

When selecting a meal replacement shake, it’s essential to opt for a high-quality and nutritious product that fits your individual needs and preferences.

While meal replacement shakes can offer benefits such as convenience, portion control, and nutrient supplementation, they should not replace whole foods entirely. Whole foods offer a wide range of nutrients and health benefits that meal replacement shakes cannot match.

Overall, meal replacement shakes can be a useful tool for those looking to supplement their diet with additional nutrients or maintain portion control, especially for individuals with busy schedules.
