Ensure vs. SlimFast vs. Atkins vs. Premier Protein: Which One is Best for Weight Loss and Diet Plan?

Can Ensure help me lose weight?

No, I want to say. It contains a lot of calories.

But some people also try to replace one meal per day with Ensure, which can reduce daily intake by about 200 to 400 calories and result in weight loss of 0.5 pounds per week.

What are Ensure and Ensure Plus?

In short, Ensure and Ensure Plus, both shakes for use in diets, are not designed to lose weight, but rather to maintain or gain weight!

Both shakes provide adequate nutrition and are recommended for people who are malnourished or who are experiencing involuntary weight loss.

What are the similarities between Ensure and Ensure Plus? What's the difference?

Both shakes are an excellent source of 27 essential vitamins and minerals you need for overall health and are rich in omega 3 fatty acids.

These shakes also differ in that Ensure gives you 220 calories and 9 grams of protein per serving, while Ensure Plus gives you 350 calories and 16 grams of protein per serving.

#1. Protein content comparison：SlimFast、Atkins、Premier Protein

In terms of protein content, we can easily see that Premier Protein meal replacement shake has the highest protein content, followed by SlimFast.

Protein is invaluable when it comes to increased fullness and satisfaction after a meal. Knowing how to use this key nutrient as part of a balanced diet puts the odds of losing weight on your side.

Protein is a nutrient that plays an essential role in building and maintaining the health of your body, including your muscles, skin and bones. 

How much protein should I eat to lose weight? Protein needs vary from person to person. Only a certain amount of protein (25 to 35 grams) can be absorbed and used at once. 

Protein has other benefits:

• Protein is used to build muscle, so it can also help prevent muscle loss when you lose weight.

• Your body burns more calories when digesting protein than carbohydrates, so protein has a higher thermic effect of food (TEF).

• Protein is harder to store as body fat than carbohydrates or fat, so even if you have too much protein, you will store less fat.

• Increasing protein intake can help reduce the accumulation of harmful fat in the body, especially around the belly.

So if the above benefits are what you value most, then you can choose Premier Protein, which contains up to 30 grams of protein.

Winner：Premier Protein

#2. Calorie content comparison：SlimFast、Atkins、Premier Protein

One of the key factors that many people consider when choosing a meal replacement shake is the caloric content.

As low-calorie diet solutions, the three meal replacement shakes, SlimFast, Atkins, and Premier Protein, are all calorie-reduced products, suitable for those who want to control their weight or reduce their calorie intake.

On average, Premier Protein shakes have approximately 160 calories per serving, Atkins shakes have 170 calories per serving, and SlimFast shakes have 180 calories per serving.

These numbers may vary slightly depending on the specific product and flavor you choose.

You gain weight when you eat more calories than you burn — or burn fewer calories than you eat.

There's no easy way to lose weight. To take in fewer calories than you burn, the Dietary Guidelines for Americans recommends cutting 500 to 750 calories a day to lose 1 to 1.5 pounds (0.5 to 0.7 kilograms) a week. 

Therefore, if you want to lose weight quickly, you can use any one of SlimFast, Atkins, and Premier Protein to replace your two meals, which can create a 500 to 750 calorie difference.

Add more physical activity to get to your weight-loss goals faster and maintain your weight loss.

Winner：Premier Protein

#3. Sugar and carbohydrate content comparison：SlimFast、Atkins、Premier Protein

Sugar has been labelled as "deadly," "addictive,” and "toxic" and it is blamed for the rise in global obesity. 

The study found that people who ate less sugar lost an average of nearly 2 pounds over a period of 10 weeks while people who increased their sugar intake gained nearly 2 pounds in the same amount of time. 

Reducing sugar intake is a priority for many wellness brands, with brands like SlimFast, Atkins, and Premier Protein all taking steps to address the issue in their products.

SlimFast, Atkins, and Premier Protein shakes typically contain about 1 gram of sugar per serving. Ultimately, choosing between the three will depend on your carbohydrate needs.

In terms of carbohydrates, they don't differ much either, with Premier Protein having the least amount. The content of SlimFast and Atkins is the same.

After all, all three of them are poster children for low-carb diets, so it seems like a tie!

This low sugar content makes it an attractive option for those watching their sugar intake or following a low-sugar diet.

Winner：Premier Protein

#4. Fiber, vitamins and minerals content comparison：SlimFast、Atkins、Premier Protein

SlimFast 

Each SlimFast protein shake contains 5g of fiber per serving, which is a decent amount for health and weight loss.

Fiber is one of the main components of a healthy diet that will keep you full, and also help minimize digestive distress. 

Since the goal of the shakes is to replace healthy, normal meals. SlimFast shakes hit the mark in this realm, providing 24 essential vitamins and minerals.

Atkins

When it comes to promoting satiety, Atkins is at a distinct disadvantage. Not only is it the lowest in protein, it’s also not high in fiber. Both of these can help you stay satisfied after meals and aid weight loss.

Atkins Shake offers 24 vitamins and minerals – all at 20 to 35% daily recommended value.

In addition, the shake includes nutrients that many people are commonly deficient in including vitamin D, vitamin B12, calcium and iron.

Along with Atkins Shakes, the company also offers Atkins bars, meal kits, frozen foods, meals and treats to help people with their low-carb dietary regimen.

Premier

Premier mentions on their site that there’s 6.6g of naturally-occurring branch chain amino acids (BCAAs) in each shake serving – providing all 9 essential amino acids.

BCAAs are important because the body needs them to make proteins. 

In addition, they’re also incredibly beneficial for muscle-building. However, we can’t produce these amino acids on our own – we have to get them from our diets.

You definitely want to choose a shake that has lots of added vitamins and minerals. Premier Protein drinks unfortunately don’t measure up as a meal replacement in this area, with only small amounts of three nutrients. The shakes contain Vitamin A (2%), Iron (2%) and Calcium (20%) per serving.

In comparison, Atkins meal replacement shakes contain 24 vitamins and minerals.

While it’s great that Premier Powder is low in carbs, it’s also low in fiber. Ideally, you want your meal replacement shake to have 5-10g of fiber per serving, and Premier Protein only has 3g.

Winner：SlimFast 

#5. Taste and texture comparison: SlimFast、Atkins、Premier Protein

Premier Protein

What sets Premier Protein apart is not just the variety of flavors they offer, but also the quality of their shakes. The smooth and creamy texture of their shakes makes each sip a pleasurable experience. 

SlimFast

Similar to Premier Protein, SlimFast also recognizes the importance of flavor variety in meal replacement shakes. 

When it comes to texture, SlimFast shakes offer a range of options. Some of their products have a creamy texture that glides smoothly down your throat, while others have a slightly more textured consistency that adds a bit of complexity to each sip. 

Atkins

Whereas the Atkins ready-to-drink shakes come in a variety of different flavors, the protein powders only come in Milk Chocolate and Vanilla.

Winner：Premier Protein

#6. Pricing comparison: SlimFast、Atkins、Premier Protein

Premier Protein

In terms of pricing, Premier Protein is the most expensive. But Premier Protein shakes are very competitively priced and can usually be purchased in packs of 12 or 18. The cost per serving may vary, but overall, Premier Protein shakes are considered reasonably priced compared to similar products.

SlimFast

SlimFast's pricing is in the middle of the pack. SlimFast shakes typically come in packs of 12 or 20 servings and range in price from affordable to slightly more expensive, depending on the retailer.

Atkins

Atkins is the least expensive option, and those who plan to stick to the Atkins diet for the long term may find it the most cost-effective.
