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.
Unfortunately, most of the studies are related to weight management, however, most research also shows improvements in biomarkers like cholesterol, iron, glucose levels etc.

However, it’s important to check the nutritional label to ensure that you get a healthy meal shake.
Different meal replacement products have different ingredients and nutrients because not all meal replacements are created equally. This is why you should choose the meal replacement supplement you want to use very carefully by reading the ingredients list and doing some preliminary research.

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
u/valens451
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.

Are Meal Replacements Healthy? – According to Our Experts
Here in Latestfuels, we’ve been consuming meal replacement shakes for over 5 years now.
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.
