Meal Replacement Shakes have been around for decades and they’re not going anywhere. They’re everywhere… places like your local GNC, supermarket, health food store, etc. They’re in traditional magazine, on TV, and all over social media outlets like Facebook, Instagram, Twitter, Pinterest, etc.

Weight Loss Shakes And Their Allure

These shakes come with a promise — to make you slimmer without needing to put forth much effort. No thinking, no exercising. Just drink the shake down and you’ll magically lose weight.

Some of the recent marketing messages I’ve seen on bottles are:

“The Lean Shake”

“Lean Shake Burn”

“Super-Lean Meal Replacement”


And without even looking at the ingredients, the shiny label leads us to believe these shakes promote weight loss.

It’s interesting because we often drink these without much concern for what’s actually in them. The same can be said for diet pills. Most people see the promise and will instantly take them, even without looking at the label and doing some research on the ingredients.

At the end of the day, we want the results promised on the label, and we’re less concerned about what’s actually in them, or how (if) they actually work.

Meal Replacement Shakes Promise Results Coupled With Convenience

If you could magically lose weight without having to learn anything and only adjust your eating habits slightly, would you do it?

Almost everyone would say yes.

And that’s why Meal Replacement Shakes have been in business for 40 years. They offer a simple solution to what seems to be a complex problem.

Their most popular message is to replace 2 meals with a Meal Replacement Shakes, indulge in 3 snacks to curb hunger, and eat your favorite 500-calorie meal for dinner.

Do the math:

An average Meal Replacement Shakes will have around 200 calories after you add 8 ounces of skim milk to the mix (as per their directions).

The total macronutrients:

  • 10g protein
  • 30g carbs
  • 5g fat

So 2 meals of Slim Fast shakes = 400 calories.

Then you choose 3 of their snacks, which are 100 calories each.

Then you have a 500-calorie meal for dinner.

400 (2 shakes) + 300 (3 snacks) + 500 (dinner meal) = 1200 calories.

1200 calories is likely two-thirds to one-half of what’s needed for a small woman who’s exercising regularly.

So if you follow the Meal Replacement Shakes plan, it’ll work for sure, but not because there’s anything special in the shakes. It’s because by default, it’s limiting you to 1200 calories per day, and half of the day’s calories are sure to be subpar because they’re coming from a low-quality powder of mostly carbohydrates (the protein comes from the milk).

It’s Just Food (And Cheap Food At That)

This isn’t a jab at Meal Replacement Shake companies. Though, I should add that if you want to lose weight safely, actually maintain your muscle, and lose mostly fat (not muscle), there are better methods

When you look at any Meal Replacement Shake label, you’ll see a bunch of ingredients that you wouldn’t normally eat if you were eating whole foods.


Meal Replacement Shakes are nothing more than food. And as I’ve mentioned before, no fat burning foods actually exist.

Fat loss happens by creating a caloric deficit, exercising regularly, and managing your caloric intake over time.

For a fat loss education, we’ve got you covered:

If A Friend Is Trying To Sell It To You, Think Twice

A very common occurrence for many people trying to lose weight or get into better shape is for a friend reveal an incredible weight loss shake or supplement they’ve been using and how it’s helped them lose weight, feel better, and get into shape.

Some of the popular shakes come from the following companies:

  • Isagenix
  • Herbalife
  • Advocare
  • ViSalus
  • Shakeology

All of these companies above are known as MLM (Multi Level Marketing), in which a company forgoes traditional marketing methods (retail stores, mainstream media) and recruits independent sales reps. Now if you’re a big fan of MLM, you’re probably going to hate me for this but I’ve got a job to do…

Most of these products are produced very cheaply and contain average (at best) ingredients. On top of that, you have to deal with slimy sales people trying to get you to purchase from them, and join their ‘business opportunity’ so you can make money consuming your ‘favorite’ products.

These above companies have some form of a weight loss shake that basically replaces a meal… In reality, it’s a formula similar to any meal replacement shake message: replace a few meals with our shakes, watch your weight fall off.

While this message isn’t incredibly bad, per se, there is a better way.

How Weight Loss Really Works

You eat fewer calories than you burn over a period of time and you lose weight. But what you eat, how you exercise, and how you rest determines whether or not you lose fat or muscle…

At the end of the day, it goes like this.

First you must find out how many calories you burn per day.

Weight loss is, fundamentally, basic math.

Second, you create a calorie deficit.

So if the maintenance calculator says you burn 2,800 calories per day (just an example), you’ll want to consistently eat less than that. I don’t recommend more than 500 calories below maintenance per day for various reasons, but you want to create what we call a ‘sustainable deficit’ which means something you can realistically stick to.

Sure, you could adopt the weight loss shake mindset and consume only 1500 calories per day, but you’ll not only lose weight fast, you’ll also lose muscle. I should also mention that you’re likely to also lose strength, and suffer throughout your diet.

How Meal Replacement Shakes Can Be Helpful

Shakes can be helpful in the following scenarios:

  • You’re short on time.
  • You want a quick, easy meal
  • You need to add some more quality protein to your diet.
  • You dislike certain veggies (spinach, kale, etc) and want to put them into a smoothie

They can also be helpful in getting you to start your day off right with a healthy breakfast, which can set you up for success later in the day to eat better and track your macros.

How Meal Replacement Shakes Can Hurt You

Weight loss shakes tend to be low in vitamins and minerals, in general — especially the ones that come in a fancy container and promise to make you look like a million bucks by drinking them alone.

Meal Replacement Shakes aren’t helpful when:

  • You replace too many of your meals with them
  • You rely on them out of laziness
  • You believe them to be your fat loss miracle
  • You think they’re a suitable replacement for good nutrition

Remember… most of these so-called Meal Replacement Shakes are created to fulfill a fabricated need in order to make your life easier and to avoid doing the work it takes to create healthy, sustainable fat loss.

Why They’re Called ‘Meal Replacement Shakes Or Weight Loss Shakes’

When you look at these labels, there is NOTHING magical in them. As I mentioned earlier, there are no true fat burning foods in existence and these shakes are just… food.

Marketers label these as Meal Replacement Shakes  or weight loss shake because most of them are lower in calories when you compare them to traditional meals and because they can server as a makeshift meal replacement.

But at the end of the day, you can create your own, healthier version of a weight loss shake as long as you have a blender at home.

A very popular approach to making your own shakes is by blending a combination of the following:

  • Fresh fruit
  • Protein powder (I like True Nutrition, or NOW brand pea protein)
  • Veggies (like kale, carrots, spinach, etc)
  • Honey, yogurt
  • Various liquids like milk, almond milk, or something similar (water works, too)

Some people put nuts in them (make sure your blender can handle it)

Why Homemade Weight Loss Shakes Are A Better Choice

At the end of the day, you’re controlling what’s in them. You don’t have to rely on a mass-produced, pre-made powder with subpar ingredients. Instead, you can load them up with all the healthy vitamin- and mineral-rich ingredients you desire. On top of that, you’re saving money.
