At TRT Center we believe that meal replacement shakes offer a simple and effective way to assist with weight loss, over the years various food models have been posited by governments around the world, and almost all of them have failed miserably. Meal replacement shakes take the guess work out of dietary requirements. Not only do they present an affordable solution to healthy eating, but they're also incredibly convienient. As far as real world application goes, there is probably little as effective as recommending meal replacement shakes for weight loss.

Meal replacement shakes take out a lot of the common pain points with people who are struggling to lose weight, such as portion control and convienience. Mostly being broken down into around 400Kcal per serving, and prepared in seconds, they provide a real working solution in this area, whereas complicated diet plans allow for under reporting calories, which most people struggling with weight loss do (see study). This led doctors to see if using meal replacement shakes for weight loss was more effective than a traditional calorie restricted diet. The answer was quite simply a resounding yes. Meal replacement shakes made the process of managing calories a lot more simple as having an easy measuring system was far less difficult to maintain so the patients were able to effectively track the calories they were intaking. The trial resulted in 93% of the meal shake patients losing 5% or more of their body fat versus 55% of the diet plan group. Meal replacement shakes for weight loss are even available on perscription in many countries, so it's well noted that they are proven to be effective.

Instant knockout complete is fantastic at reducing hunger cravings, making it ideal for people restricting their calories.

Instant Knockout Complete Is Used By Athletes

Instant Knockout was designed for fighters who need to drop weight quickly for weigh ins without losing muslce. So, they want to lose fat fast, but not the muscle they have.

What Flavours Of Meal Replacement Shake Are There?

This is the one let down of Instant Knockout, as a new meal replacement shake there aren't a great deal of flavours available. It currently only comes in vanilla, but generally speaking when it comes to everyday drinking vanilla is often the best all rounder for most people.

The Original - Market Leading Meal Replacement Shake

Huel

Come on it's Huel, we couldn't not talk about them, but the question that comes up is, which version of Huel should we talk about? At this point they have versions that are high protein, and they have complete meal replacement shakes that are more balanced. There's so much variety in their product range that it's even hard to nail them down on taste or ingredients. Huel is probably the meal replacement shake that you've heard of, it's also one of the most conveinient meal replacers, with it being available pre made in most stores. Whilst it isn't quite the original, with meal replacement shakes being used medicinally for years before it's launch, it is perhaps the first to bring a complete meal shake to a large audience.

Which Huel Is The Best Meal Replacement Shake For Weight Loss?

Technically the answer is Huel Black, but, that does assume that you like Huel Black, whilst it is the best meal replacement shake for weight loss and muscle growth as it packs the most protein, it definitely doesn't taste the best. And flavour matters, for most people on the first step of their weight loss journey we tend to recommend better tasting shakes as transitioning to healthier eating habbits isn't always the easiest thing to do. Huel does have the advantage of having a flavour for everyone though, so it's almost certain you can find one that you like.

Who Should Use Huel Black?

  • Vegans who need more protein
  • Huel fans
  • People looking for a known quantity meal replacer

Does Huel Black Work For Weight Loss?

Short answer yes, but as you can see by it's position on our list we'd recommend that you pick a different meal replacement.

What To Look For In A Meal Replacement Shake

When deciding on which meal replacement shake is right for you, you'll want to look at the following things, the ingredients, the calories, the fillers and the macros. Don't worry this isn't as complicated as it sounds. Some of this is going to vary across purposes, for example, if you're trying to build muscle then you'll want higher protein, as a rule of thumb this will be at least 1g for every 2lb of your body weight. After that it's not so important where you get your calories from, but remember higher protein will keep you fuller for longer. You'll want to avoid fillers where possible as these are generally unhealthy so when you're looking for healthy meal replacement shakes you'll want to keep an eye out for the below.

Dietary Aids And Enzymes

These will help your body break down the food that goes into it and help keep your gut healthy, most good meal replacement shakes are fortified with the correct enzymes to help you process the shake effectively. 

Macros

Macros are the main thing we look at when creating a balanced meal, they're looking at diet in a broader sense, which is why we call them macros, an ideal blend should be around 50% carbs, 30% proteitn and 20% healthy fats.

Vitamins and Minerals

A complete meal replacement shake should have the right amount of vitamins and minerals to make sure you reach your recommeneded daily intake, that means if the shake contains 20% of your days calories it should also contain 20% of your daily vitamins and minerals or "micro nutrients". All the ones on our best meal replacement shakes do.

Omega 3 & Omega 6

This is particularly important with vegan meal replacement shakes as there are very few sources of essential omega oils (which are needed for brain and joint function) outside of fish or ludicrous consumption of walnuts and flax seeds. So, having refined versions of these becomes incredibly important for people following vegan diets, typically most meal replacement shakes get omega 3 and 6 from chia seeds or flax seeds.

Fiber and Prebiotics

Everybody poops, and if you want to keep your digestive system happy you're going to need fibre, and probiotics, again all the shakes on our best meal replacers list contain the right amount of these, but if you're opting for cheaper brands make sure to watch out for this, especially if you're using meal replacement shakes for weight loss, as these are likely to be quite full of chemicals.

Allergens

You'll of course want to look out for allergens, this could mean making sure you find a lactose free meal replacement shake, or checking for nut allergens. This will of course be dependant on your personal dietary needs.
