Losing Weight with Meal Replacement Shakes

Losing weight isn’t easy. If you’re looking for a way to simplify what you eat, detox from unhealthy eating habits, and reach your health goals, mixing some liquid meal replacements into your diet could be a great way to start.

Replacing meals like fast food when feeling hungry at work is what I recommend as a starting point. Fat loss is possible the moment you decide exactly what your weight loss strategies will look like. You can even find a social meal replacement group on sites like facebook!

I can speak from my own personal experience, you can lose weight with meal replacements. I lost 140 lbs with the assistance of meal shakes. You CAN use meal replacement shakes to help you too. 

Furthermore, a meal replacement diet is a great way to lose weight quickly - if you follow some of the guidelines I mention here.

The Best Nutrition for Losing Weight on Meal Shakes

If you don’t have time to prepare healthy meals and want to fix unhealthy eating habits, then you should know a little bit about all the nutrients that meal replacement shakes provide. 

Part of a healthy body weight and change of diet involves getting enough of the nutrients that I’m about to talk about. Not only will meal replacement shakes help you get the nutrition your body needs - but they will also help you stay full.

Your meal replacement should have a good amount of protein, fat, and fiber. And some of them are even suitable for a keto diet! According to the research, a lower-carb, higher glycemic index diet can keep you healthier. 

Are meal replacements healthy?

There are many brands of meal replacement drinks made for everyday life, and also for purposes like weight loss and sports recovery. Compared to the average American diet in the U.S., it does an excellent job at addressing health concerns. 

Products like Huel, Soylent, and Jimmy Joy have a relatively low glycemic index thanks to low-sugar and slow-digesting carbs, 20+ grams of protein, and other ingredients that aid in helping you lower blood pressure and blood sugar levels. 

Instead of being sweetened by sugars, Soylent contains artificial ingredients like certain flavors and sucralose.

Basically, high-quality meal replacement shakes contain the same amount of high-quality nutrition, if not better, than the average meal (especially fast foods.)

What makes a Meal Shake “healthy”?

If you do your own research, you’ll find a huge difference between the quality of ingredients between brands. I strongly recommend against brands you can buy in stores because of lots of added preservatives and low-quality sources.

The main macronutrients: Carbs, Fats, and Proteins dictate what is considered healthy. A good meal replacement shake should be relatively low in carbs and packed with protein. Besides that, fat will help keep you fuller longer.

Carbohydrates in Meal Replacements

Besides the big box store brands (like Ensure, etc), most meal replacement beverages don’t contain a lot of added sugars. Added sugar would spike your blood sugar levels and hinder your weight loss journey. The sources of carbohydrates in healthy meal replacement shakes are often plant compounds that take a long time to digest.

Protein in Meal Replacements

Protein is a huge factor in helping keep you full during the day. 

If there’s one thing meal replacements are great at, it’s making sure you get enough protein in your diet - essential for weight management.

Many meal replacements like Soylent or Huel provide plant based protein (like pea protein). Other kinds come from whole grain. This is especially great if you’re looking to try meal replacements to reduce meat consumption. 

For the average non-athlete, it's perfect, but I would need to supplement more protein to maintain muscle mass. There are brands that make high protein meal replacements like Huel or Feed. 

Fat in Meal Replacements

The secret to having lost weight like I have is NOT low fat. Even saturated fat is fine within the context of a balanced diet. Meal replacement shakes, just like a complete meal, should contain healthy fat.

Good fats include monounsaturated and polyunsaturated fats (that’s the advice coming from medical professionals). But if you’re eating a low-carb diet, saturated fat is part of the equation. But most meal replacement shakes don’t contain a lot of those kinds of fats.

Many keto meal replacements will have you add in your own fats - like oils, heavy cream, or butter. If you want to use meal replacement shakes AND do a keto diet, there are some specialized brands that will help you lose weight and do keto. 

We talk about it here in our article about keto meal replacement shakes.

Micronutrients in Meal Replacements

Some meal replacement shakes, especially keto shakes like Keto Chow, contain a better profile of electrolytes - salt, potassium, magnesium, calcium than most whole foods. This will help reduce hunger and increase energy on a diet with fewer calories.

The average American diet is lacking critical nutrients that assist you with weight loss. In fact, 4 of the most important ones for feeling full: Fiber, Sodium, Magnesium and Potassium. Without these, especially fiber, the stomach is triggered to be hungrier sooner. 

In the next section, we will go over the best shakes for covering that nutrient gap.

Tailor Your Liquid Meal Replacement to Your Needs

The best meal replacement will depend on your needs and calorie intake. The only thing you need to lose weight is fewer calories, but you also want to make sure the meal replacement shake tastes good!

Now that you’re thinking about drinking meal replacement shakes to aid with weight loss, you might be wondering what the best brand and type of shake would be to drink.

I’ve tried so many different meal replacement shakes that I can barely count them, but I can’t provide medical advice. You should talk to a doctor about which shake fits you best, especially if you have any health conditions.

Meal replacement products should do their best to mimic a full meal with whole foods.

The 10 Most Important Factors to Meal Replacement Products

  • Getting enough calories
  • Getting enough protein
  • Low glycemic index carbs
  • Healthy fats (low saturated fat)
  • Essential Vitamins and Minerals (such as vitamin C/vitamin D) 
  • High Fiber
  • Micronutrients
  • Electrolytes (potassium, magnesium)
  • Overall quality and source of ingredients
  • Quantity of liquid

Remember that low calories does NOT = a better shake for weight loss!

You should use a net daily energy calculator to find out how many calories you need to eat to lose weight. Generally, for women this would be lower than 1500 and 2000 for men. But I don’t recommend going lower than 1200.

What to do when you find the right shake for you:

I recommend starting with replacing 1 or 2 meals a day with shakes. Breakfast and lunch are usually the easiest. Work your way up, and be careful about how much fiber you are getting if you are not used to a high fiber diet. Too much too soon can cause stomach problems!

Now that we know what to look for in a high quality meal replacement shake, let's talk about the most extreme version of dieting with meal replacement shakes!

Trying a 100% Meal Replacement Shake Diet

I spent about 2 months strictly consuming meal replacement shakes and I felt great. I stopped needing to take naps, lost a ton of weight, felt fuller for longer, and ended my sugar cravings.

My blood tests, EKG, physical, etc showed that I was in the best shape of my life. Even though I’ve reached most of my weight loss milestones, I plan on using liquid meal replacements to save time for the rest of my life.

But this is an extreme option and not easy to pull off…

Don’t get me wrong, it was worth the 15 lbs I lost, but getting to the next meal without something solid in my stomach was always a challenge.

Please remember that you can’t just drink protein shakes and survive off of that. Take a look at the best shakes list above for ideas.

Here are some ideas for how to space out the meals so you don’t get hungry:

Meal Plan 1:

12 PM: 500 calorie shake

8 PM: 2x 500 calorie shake

Meal Plan 2:

12 PM: 500 calorie shake

4 PM: 500 calorie shake

8 PM: 500 calorie shake

Meal Plan 3:

8 AM: 350 calorie shake

12 PM: 350 calorie shake

6 PM: 2x 350 calorie shake

The one thing I DO NOT recommend is immediately jumping from normal food, 0 calorie restriction to a 100% meal replacement shake diet...

In other words, to start out, I recommend replacing only one or two meals a day with a high-protein shake like Huel. You can check out our Huel article here. 

You may need more calories than what I listed, especially if you are a man. Weight loss is a marathon, not a sprint. 

If you starve yourself, you’ll be in bad shape and more likely to rebound to an unhealthy diet.
