How to Use Meal Replacement Shake for Weight Loss

Compiling many studies together, science says that partial meal replacement programs can yield slightly more weight loss than low-calorie meal plans in the short term in the range of 1 to 3 months. Sounds pretty good?


Many people join weight watchers program still they fail. Short term weight loss is one thing, but the far more important question is long-term weight maintenance. It’s easy to follow a restrictive program for a few months, but what about a year or two or more down the line.  A new study was published in late January 2019 that came to different conclusions but that just how science works. Here’s our analysis based on the latest evidence.


Researchers asked whether partial meal replacement programs were more effective for weight loss than diet alone? They addressed this question by compiling 23 studies together. These partial meal replacement programs included shakes but also bars and pre-portioned whole food meals. Most of these studies had an active weight loss phase of 3 to 6 months with more stringent use of meal replacements followed by a weight maintenance phase where meal replacements were generally recommended to be used once per day.


Partial meal replacement programs yielded more weight loss than diet alone after one year, but here’s what we think are the most striking findings. Significantly more subjects achieved clinically meaningful weight loss with partial meal replacement programs plus additional support. Weight loss greater than five to ten % of total body weight is considered clinically meaningful because it’s associated with improved health outcomes, like blood glucose control and insulin sensitivity.


What about that additional support? This included both individual and group weight-loss sessions with dieticians and health educators. These sessions focus on weight-loss strategies and motivational support.

Our takeaway from this analysis is that partial meal replacement programs can yield more weight loss than diet alone when used as one tool among many within a supported weight-loss program. This interpretation was supported by the Academy of Nutrition and Dietetics who stated that partial meal replacements can be helpful for adherence to a low-calorie diet through convenience, portion control, restricting dietary variety and reducing problematic food choices.


But what about longer than one year. Specific shakes haven’t been evaluated at this extended time frame. But there are some other studies that can help address whether meal replacements, in general, are important in the long haul. The look-ahead study investigated a comprehensive weight loss program that introduced many different strategies for weight loss and maintenance. Over eight years some people maintain their weight loss while others regained. Both the maintainer and the regainers said they use the meal replacement shake the same amount, suggesting that shakes aren’t the key to long-term weight maintenance.


The maintainers did report more physical activity, self-weight monitoring and more frequent low-calorie food intake. Suggesting that these strategies may be more important for keeping the weight off.


Our conclusion, when making major dietary changes, you should consult a registered dietician for individualized advice. It’s difficult to come to strong conclusions for the shakes on our social network feed today because they haven’t been individually studied. The best evidence we have shows that partial meal replacement programs which include shakes but also bars and pre-portioned whole food can enhance weight loss at one year.


If you’re looking for meal replacement shakes to lose weight, make sure to incorporate it with other healthy behaviours, like physical activity and nutrient-dense food like these recommended vegetables for weight loss. Solely relying on shakes isn’t sustainable in the long haul. 


Remember that meal replacement shakes are not usually harmful if they are used as directed. Learn about with help from a registered and licensed dietitian in this free video.


Are Meal Replacement Shakes Harmful to Your System?


You can also follow the paleo diet which encourages us to eat less processed food, less high-fat and high-sugar foods and more fruit and vegetables. Remember that reducing high-calorie foods will reduce calorie intake and help you lose weight faster.


All in all its very important to research your options and know what result you want. Our recommended best quality shakes are high in protein, vitamins and minerals and low in artificial flavouring & colour and sugars.

How do Meal Replacement Shakes work for weight loss?

It totally depends on how much weight you are trying to lose and how fast. Unlike the protein shakes, meal replacement shakes are designed to provide the nutrition that we take from a full meal. Most of the meal replacement shakes that we buy comes in powdered form which we mix with milk or water or meal replacement bars. They contain a good amount of protein ranging from 200–400 calories added with fibre and essential minerals and vitamins.


This is the reason meal replacement shake is an easy way to get a healthy and very low-calorie diet on the go. There are many different brands that are available in the market and their nutrition compositions and nutrient can vary with various proportions of fat, carbs and protein as well as other ingredients.


Here is the overview to investigate whether these shakes help with weight loss or not:


1. It Helps You to Avoid Junk Meals

Meal replacement shakes are very easy to drink and very convenient and portable. In this way, you resist yourself from taking unhealthy processed foods which is complete junk. We know that it takes time to prepare your healthy meal regularly and this is one of the barriers when trying to lose weight.


When we are in a rush or in a hurry in our busy lifestyle, we tend to grab junk food or eat fast food. Unfortunately, these unhealthy processed junk food doesn’t help us to achieve our weight loss goals.  These foods contain refined carbs, artificial ingredients, lot of sugar and salt and don’t provide any nutritional value.


Also, these ingredients in processed foods activate our pleasure centre of the brain and we end up eating a lot. If you really want to lose weight then you must follow a healthy diet made out of whole food, but is it practical with a busy work schedule? This is why we recommend meal replacement shakes are easy on the go drink and best alternatives to fast foods.


2. It Provides Complete Nutrients

Meal replacement shakes that we drink are designed to provide full nutrients that we should get it from a complete meal. When we cut back calories to lose weight, you are not going to get all the nutrients your body needs from your diet. These diet shakes are fortified with all the necessary nutrients and vitamins which will fill up the gap while you are cutting back on calories.


The best quality meal replacement shakes must contain all the protein, fibre and vitamins and minerals that our body need. There are many commercial brands, they add other nutrients like vitamin D, iron, calcium and potassium which many of us is lacking from our regular meal.


3. Meal Replacement Shakes Help You to Lose Weight Fast.

If you really want to lose weight fast then you must reduce your calorie intake. However, it is very challenging to follow a low-calorie diet, because we end up feeling not satisfied and hungry. Meal replacement shakes is the best option which will make you feel full and your calorie intake will be low.


If you want to speed up your weight loss goal then it is suggested to replace one of two meal a day with a nutrient-dense meal replacement shake.


There was a study where the participants who followed a partial meal replacement diet plan lost 2.4 kg in 3 months’ time frame comparing to those followed food-based reduced-calorie diet plan.


Another study has found that diabetic patients who followed meal replacement shake diet plan lost weight. They also had low blood sugar and LDL cholesterol levels contributed to slightly greater weight loss than conventional dieting.


The good thing about the meal replacement shake is, it helps with weight maintenance after losing weight.


4. Shakes with High Protein Helps Weight Loss.

There are many different types of meal replacement shakes and their protein content are not the same. A good meal replacement shake may contain high in protein which is actually important for weight loss. When we take a high protein diet, it leads to greater satiety. It helps us eating less thought out the day that means we intake low calorie.


There was a study on men who were on a high protein diet, reported a reduced desire to eat late at night and lowered their cravings compared to those consuming a moderate amount of protein.


There are many other benefits when we take high protein diet like it will increase lean muscle, reduce body fat, less fat on the belly as well as improved weight maintenance.


This is why our recommended meal replacement shakes are high in protein and low in sugar.

Why Powder Meal Replacements is Best Choice?

Top liquid meal replacement shakes

There are two types of meal replacement food available- powder and solid bars. Here the important factor is usability. You got the option to choose either pre-packaged bars or powder shakes. If you choose solid bars then it’s more satiety and as well as resemble normal eating patterns. This is why many weight loss programs recommend this.


But powder shakes mixed with any liquid is easy to digest and consume. According to some research, when you consume food in a liquid form; it tricks your stomach thinking that it is full than it is. If you take blended food, it would make you feel much fuller compared to if you eat solid bars.


Powder meal replacement shake can move quickly to your digestive system because you make it in liquid form. Think it this way, when you take your meal replacement in a liquid form, it spends less time compared to solid bars. It reaches your intestine very fast and the nutrients can absorb quickly. This is why powder shakes are the best choice for post-workout recovery when you are trying to lose weight and support your damaged muscle during exercise.

Why Meal Replacements is Better than Deprivation Diet to Lose Weight?

If you follow deprivation diet meaning fat restriction or very low-calorie food then there is a chance that you will develop metabolic disorders. Because the food you eat is not nutritionally complete. The side effects include feeling very hungry all the time, low on energy, headache, dizziness and dry mouth. In a short term, you will lose weight but it will come back on when the diet ends. This is why many weight watchers fail to lose weight.


Many studies suggest that your weight loss goal is more successful when it contains health foods that include all kinds of balanced vitamin and minerals that you get from meal replacement food. A recent study found that when you take meal replacement food, it will promote a healthy level of insulin and leptin. It will not be the cause of the metabolic disorder.


In short, your meal replacement diet will keep your hormone level balanced. It’s a win-win weight loss plan.

What is the Difference Between Meal Replacement Shakes, Diet Shakes and Weight Loss Shakes?

Specifically, meal replacement shake is designed to reach your weight loss and weight maintenance goals act as diet shakes or weight loss shakes. Most meal replacement shake contains a high amount of calories on the other hand diet shakes or weight loss shakes are low in calories, while still being rich in nutrients.


In addition, healthy weight loss shakes and diet shakes should have little to no added sugar. Instead, they are sweetened with plant-based sugar alternatives that won’t negatively affect your blood sugar levels.


Meal replacement shake contains high-quality protein for a which is one of the factors affecting healthy metabolism, fibre for good digestion & satiety, healthy fats, and a variety of whole food nutrients for optimal health.

What to look for when buying weight loss shakes

checking meal replacement shake buyer's guide

When you are looking for the best meal replacement shakes online, you should take into consideration the general characteristics of each shake you buy, such as the quantity of protein, calories per serving, taste, and price. You should also take into account specific nutrition and ingredients information, such as carbohydrates, fibre, probiotics, sugar & artificial sugar substitute.


1. Protein Quality

All proteins are not created equal whether it’s protein shakes or protein powders. Some of them are cheap and some are expensive. Some of them act fast; others act more slowly. Some are mixed with fillers; others are pure.


The types of protein matter a great deal, when it comes to healthiest meal replacement shake. There are many meal replacement shake on the market using a wide variety of different protein types; from animals, from plants, and from soy. Depending on your dietary restrictions, find your option.


2. Price

The cost of a protein shake is often, an indicator of the quality of the ingredients. A common rule of thumb is to avoid low-cost protein shakes as they usually have soy fillers, artificial sweetening agent, and other controversial additives. All these are very counter-productive to weight loss. Nonetheless, price is a major point to consider – and is highlighted in all shake ratings.


3. Protein Amount

Some of these shakes actually “overdue†it, as they are loaded with more protein than the human body can absorb — around 10 to 25 grams at a time. (Excess protein gets eliminated from the body and can cause weight gain.) We look for the best low-calorie meal replacement shakes or blends and note their value on each description.


4. Appetite Suppressing, Natural Ingredients

Ongoing studies bolstered by everyday experience have proven that if you’re still hungry after drinking a shake, you are more likely to snack and lose any weight loss benefits the shake may have offered. The ability to effectively suppress appetite is worth its weight in gold.


We prefer natural ingredients that have been clinically studied and proven to be the most effective in staving off hunger. Our highest ratings go to those formulations with natural ingredients that perform best. We have found that a blend of ingredients works better than any single supplement.

5. Taste, Sweeteners and Sugar

It is well known that beauty is in the eye of the beholder. Taste is very much the same. Not everyone prefers the same flavours, and not everyone has the same preferences for “sweetness†when it comes down to protein shakes. Research shows that if you don’t like the taste of a protein shake you will not continue to use it, thus rendering it worthless as a weight-loss tool.


On the other hand, a shake that tastes great because of high amounts of sugar and other artificial sweeteners isn’t going to help with long term weight loss. This is why you must consider both taste and sweeteners as part of your evaluation. Low sugar meal replacement shakes should be one of your priority.

Is There Any Side Effects

It’s rare, but they could occur. Read the label carefully and allow time for your body to adjust first. Shakes are typically harmless. They’re an easy way to ensure you receive all the necessary vitamins and minerals depending on what product you buy. Some common reaction can be vitamin excess, as it is likely you get everything you need for healthy and balanced diets. Water-soluble vitamins like B and C unlikely to have issues if taken in excess as they are excreted in the urine. Fat-soluble vitamins – D, E, A, K – can hang out in your body much longer, and excess can cause a variety of issues like irritability, nausea, vomiting, and diarrhoea.
