Are Slimfast Protein Shakes Healthy

How To Use Meal Replacement Shakes

SlimFast Original Shake Mix Review – Great Nutrients But Low in Protein?

In reality, having a meal replacement shake on its own isn’t enough. The best way to enjoy a meal replacement shake is to pair it with healthy snacks that can help you turn it into a full-on meal. This way, youre feeding your body all the nutrients it needs to keep you moving throughout your day.

For every meal, you should aim to consume roughly 325 to 400 calories, 15 to 25 grams of protein, 5 grams of fiber, and 10 to 13 grams of healthy unsaturated fat, says Wendy Bazilian, DrPH, RDN, author of The SuperfoodsRx Diet. Otherwise, you’ll likely get hungry again fast.

Here are 12 store-bought meal replacement shakes that stack up nutritionally. Plus, exactly what you can pair them with to make them more filling on-the-go.

The Slimfast Plan Calls For Drinking Two Shakes And Eating One Meal Per Day

SlimFast sells meal replacement shakes, meal replacement bars, and snack bars. But what they’re really selling is the SlimFast plan, a diet they say will help you lose weight. According to the SlimFast website, the SlimFast diet requires that you drink two meal replacement shakes and eat one “sensible” meal per day. The traditional shakes contain a balance of protein, carbs, and fat, while the new Keto shakes are high fat and low carb.

You might be wondering what a sensible meal entails, exactly. Although the SlimFast website doesn’t spell it out, WebMD explained that your one meal on the SlimFast diet should contain around 500 calories. Presumably, a “sensible” meal is one that contains a combination of vegetables, lean protein, and high-fiber starchy carbs like whole grains and potatoes. However, the focus of the SlimFast diet seems to be more on how many calories you consume than what kind of food you eat, so it’s probably within the rules to eat any type of meal as long as it clocks in at right around 500 calories.

Why Slimfast Diet Is A Bad Idea

Its unsustainable. For starters, diets like this one are not sustainable over the long run. While you might lose a few pounds while youre on it, SlimFast does not set you up for success. It sets you up to become a slave to a billion dollar multinational corporation.

Whatever issues you have with food, whether its emotionally eating, not knowing how to cook healthy meals or looking for a quick fix, itll still be there. Unless youre committed to staying on SlimFast for the rest of your life, choosing this diet will not address the underlying problem. And I promise, real life will get in the way.

The ingredients are not good for you. Essentially, you could take a big glass of water, dump some sugar in it, add a crushed up multi-vitamin, add a few drops of milk, chuck in some cocoa powder and oil and have a drink very similar to SlimFast and hey, itd be cheaper!

Its expensive. Speaking of prices, SlimFast doesnt come cheap. At two shakes and three snacks a pop, youre going to be shelling out quite a bit of money. You can certainly get more bang for your buck with fresh or frozen fruits and veggies.

Sugar can make you fat. Because SlimFast foods are so full of sugar, you might be running a hamster wheel when it comes to keeping the weight off. Sugar affects leptin, the starvation hormone. Leptin is secreted by fat cells. As our fat cells increase, they secrete leptin, which tells the brain that were full and dont need more food.

What Brunilda Nazario Md Says:

Does It Work?

Yes, Slimfast can work for weight loss. Structured programs, like this one, work for people who don’t want to count calories. Studies show that people lose more weight when they eat portion-controlled meals or meal replacements.

Low-calorie diets, such as the Slimfast diet or the use of one or two meal replacements, promote weight loss and can help you keep it off longer.

Is It Good for Certain Conditions?

Conditions such as diabetes, high cholesterol, and high blood pressure are driven by extra weight, so cutting calories must be part of their treatment.

Anyone looking to lose weight on a calorie-restricted diet should work with a nutritionist or their doctor. Since the fastest weight loss happens during the first few weeks of dieting, your doctor may need to adjust any drugs you take, such as insulin or blood pressure medications.

Weight loss can make your blood sugar levels drop. Dizziness, fatigue, and other symptoms of low blood sugar may mean you need to check your blood sugar levels more often.

The Final Word

This diet works well for weight loss. One of its major highlights is calorie restriction through meal replacement — and this works for maintaining weight, too. Losing weight may be the easiest part of dieting. Sticking with a lifelong plan and keeping the weight off is where meal replacements like Slimfast and Slimfast Advanced Nutrition shine.

The Role Of Protein And Fiber In Meal Replacements

Plant-based proteins like soy tend to be one of the main ingredients in many meal replacements. In some products, dietary fiber also plays an important role. This combination has a reason for being: both of these components help to manage hunger and appetite.

Hunger and appetite, although sometimes used as synonyms, are not the same. Hunger refers to a physiological need to eat, while appetite is the desire to eat. People may report the desire to eat in the absence of hunger. Apart from physiological factors, the sensorial exposure to food, such as sight, smell, taste, has been shown to increase appetite.

But how exactly do plant-based protein and fiber contribute to satiety?


  • You are most likely to feel fuller after eating protein than other nutrients such as carbohydrate or fat.
  • Protein is digested more slowly than carbohydrate, which means it is present in the gastrointestinal tract for a longer time.
  • Plant-based and animal-sourced proteins have a similar effect on appetite.
  • Soy-based foods are not only a source of high-quality protein but also a source of fiber.


Because protein is such an important ingredient in meal replacements, there is some confusion about whether they are the same as protein shakes. They are not, and youll see why.

Slim Fast Original Nutrition Overview

Slimfast Shakes Don’t Contain As Many Calories As You Might Expect

The thing about the SlimFast meal replacement shakes is that they’re far lower in calories than your typical meal. Each one of the original SlimFast shakes contains between 180 and 190 calories, 5 grams of fat, 25 grams of carbs, and 10 grams of protein .

The brand also have two additional lines of shakes with the same number of calories but different nutrients compared to the original shakes. The Advanced Nutrition line is higher in protein and fat and lower in carbs, with between 180 and 190 calories per shake, 9 grams of fat, 7 grams of carbs, and 20 grams of protein, whereas the Keto line is higher in fat and a little lower in protein than the Advanced Nutrition line, with 180 calories, 14 grams of fat, 7 grams of carbs, and 8 grams of protein.

No matter which line you choose, the bottom line is that the shakes are very low in calories. While all contain fat, protein, and fiber to help keep you full, it’s likely that this small amount of calories won’t be enough for many people.

What Is The Slimfast Keto Diet

The rules of the SlimFast plan are simple. Each day you have two SlimFast meal replacement shakes from a shake mix, three 100-calorie snacks, and one 500 calorie meal. The 500 calorie meal is optional.

Each meal replacement smoothie contains about 180 calories. Add that to the snacks and the small meal and youre at 1200-1300 calories per day. For men, the plan recommends adding another couple of optional snacks, for up to 1600 calories a day.

The Slimfast Plan Isn’t Much Different From Other Low

SlimFast Chocolate Cherry Cheesecake Smoothie Recipe

There’s nothing all that special about the SlimFast plan. Really, it’s just a gimmicky way to eat fewer calories by replacing two meals a day with processed, low-calorie shakes or snack bars. You could lose weight sans the shakes by replacing two meals per day with a 200-calorie bowl of cereal, salad, or slice of pizza.

“Sometimes people on meal replacement plans like this see immediate results because the diet is a shock to the body,” registered dietitian Amy Goodson told Everyday Health. “You may be losing a bit of fat at the time, but it’s more likely water weight initially.” She added that you can’t keep that rate of weight loss eventually it will slow down or stop altogether.

As with all weight-loss diets, you just can’t expect to continue losing weight so rapidly, since all of your water weight will be gone and fat loss is a much slower process. And, as with all low-calorie diets, you can expect to lose one to two pounds per week.
