Slimfast Diet; Shakes, Reviews, Plans, & Results

The Slimfast diet is one of the most popular diets that started over 40 years ago. It is a diet designed to help you lose weight quickly and safely through the use of meal-replacement shakes that are high in fat and proteins.

Products from SlimFast are made for those who want to lose some pounds swiftly and easily. They can be a good option for people who are busy and trying to lose weight because the products are low in calories, and you can take them anywhere you want, like work or anytime you want to go out.

Also, SlimFast products are often bought by people who want a simple diet plan that doesn’t require a lot of grocery shopping, preparation, and cooking.

But bear in mind that some products aren’t inexpensive and might not be suitable for all budgets.

In this article, we will cover everything related to the Slimfast diet, including how to start, Slimfast shakes, results, and reviews. So, continue reading. 

How does Slim Fast work?

A Slimfast diet is a low-calorie diet and effective weight loss plan that allows you to eat fewer calories while still getting the essential nutrients your body needs. 

The main focus of the plan is to reduce your caloric intake and replace it with foods that are high in protein, low in fat, and full of vitamins and minerals. 

The Slimfast diet plan includes three meals a day, two snacks, and one meal replacement shake or bar.

The Slimfast diet provides different diet plans to manage your weight loss by having around 6 meals daily:

  • 2 Meal replacement shakes
  • 3 Low-calorie snacks (100 calories) like fruits, vegetables and nuts. However, you can have Slimfast snack bars
  • 1 Meal (500 calories)

You can form your Slimfast meal plan in the following way: 

  • Breakfast: Meal replacement shake + bar, or cookie 
  • Midmorning snack 100-calorie SlimFast snack 
  • Lunch Meal replacement shake + bar, or cookie 
  • Midafternoon snack SlimFast 100-calorie snack 
  • Dinner: a healthy recipe of your choice + 100-calorie snack of your choice 

With SlimFast, you have many choices, including shakes, sweet snacks, and meal bars to replace your meals with.

Once you’ve accomplished your goal weight, you can use SlimFast to maintain your ideal weight.

As we know, the SlimFast plan is a meal replacement diet, which means that you can replace breakfast and lunch with a Slimfast protein shake or a bar. 

How to make a SlimFast meal?

For the meal you provide, you should divide your plate as follows:

  • Half of your plate with vegetables
  • The quarter with lean protein
  • A quarter with starch (brown rice, potatoes, corn, whole-wheat bread or pasta).

Slimfast diet calories

Following this way, you can reduce your daily calorie intake. The SlimFast diet provides roughly 

  • 1,200–1,300 calories per day for women
  • 1,600–1,700 calories per day for men

However, one of the major downsides of the Slimfast plan is that you have to purchase a large part of your daily food intake in the form of SlimFast products. 

How to start a Slimfast diet?

To start the Slimfast diet, there are simple steps that you have to follow to find the plan that fits you. After all, the Slimfast diet came up with multiple plans that align with other diets like the keto diet and the low-calorie diet.

  • First, head to Google Play and download the SlimFast app which is called the “SlimFast Together app”. 
  • SlimFast offers four plans: Original, Favorite Foods, Low-Carb, and Keto.
  • If you are unsure which plan to start with, take the assessment. 
  • The app will provide you with a personal plan based on your goals, preferences, and lifestyle.
  • Choose an existing meal plan or create a customized meal plan for your first week. Download the created grocery list and stock up. 
  • You can choose a ready meal plan or create your personal customized meal plan for the week. 
  • The app will create the grocery list you need to start.
  • You will receive a quick-start guide and a 7-day meal planner with this plan to assist you in staying on track.
  • Track your weight, measurements, food and water intake, exercise, sleep, and stress level using the app.

Slimfast plans

You can choose to follow one of four versions of this plan:

Original plan 

This program makes use of well-known SlimFast products that have been available for more than 40 years. 

But it seems that the business is gradually discontinuing this way in favor of the Favorite Foods, Keto, and Low-Carb plans.

Favorite foods

This diet allows for one “SlimFast approved” meal per day as long as you stay within your calorie restrictions and do not have any specific macronutrient goals.
This is regarded as the straightforward and most flexible plan offered by the company.

Keto Slimfast plan

Designed for people following a keto diet,

This plan focuses on a high-fat diet by combining SlimFast keto products and one “sensible” keto meal. 

This plan is the hardest to stick to because you have to hit very specific macronutrient goals to stay in ketosis.

Low-Carb Slimfast plan

The Low-Carb Plan, in contrast to the Keto Plan, places more emphasis on cutting back on carbohydrates than it does on eating a high-fat diet.

  • No matter whatever plan you select, you will be required to prepare one meal per day on your own. 
  • There are restrictions on what foods to include, and the firm suggests keeping the meal’s calorie count under 600.
  • Choose from the several recipes on the Slimfast website and mobile app.
    A SlimFast shake, smoothie, or bar will take the place of the remaining portions of your meals. 
  • Additionally, you are permitted three 100-calorie snacks from the SlimFast snack line each day.
  • The high protein content of some SlimFast meal replacement products may also aid in appetite suppression.
  • The SlimFast diet also states that by having frequent meals and snacks, your metabolism will remain active.
  • The program also suggests including at least 30 minutes of activity each day in addition to the diet to help produce the calorie deficit required for weight loss.

Exercise on the SlimFast diet

Simply incorporating 30-60 minutes of moderate-intensity exercise each day will help you lose weight and improve your overall health.

Vegetarians Slimfast plans

For their daily meal, vegetarians can consume 4 to 6 ounces of a meat substitute like quinoa, tofu, lentils, or black beans. 

Low-fat dairy products like yogurt, milk, and cheese are also acceptable. 

Since most meal replacements are made with dairy products or eggs, which are not permitted in a vegan diet, there are fewer options for vegans.

Slimfast keto plan

A meal with 500 calories is reasonable on the keto diet. Even though SlimFast also provides recipe ideas, your weekly grocery list will change depending on the particular meals you’re replacing. But this list might incorporate:

Women on the SlimFast Keto plan adhere to a 1,200–1,300 calorie diet while men consume 1,600–1,700 calories per day, similar to the original SlimFast plan.

A high-fat, low-carb diet called keto is meant to put your body into ketosis, a metabolic state where fat is burned as fuel instead of carbohydrates. You won’t find high-carb foods like bread, pasta, crackers, or even many fruits on a keto diet menu; instead, you’ll find high-fat foods like skin-on chicken thighs, avocado, and olive oil.

On the SlimFast Keto diet, you will consume three 100-calorie SlimFast Keto snacks, two low-carb, high-fat SlimFast Keto meal replacements (such as shakes or meal bars), and one healthy, keto-friendly meal of your choosing.

Results of Slim Fast diet

By following the SlimFast diet, you can expect to lose 1-2 pounds (0.45–0.91 kg) each week.
The size of your calorie deficit, which is based on how many calories you take in and burn off through exercise, determines how much weight you will lose using SlimFast.

  • Participants in a SlimFast study lost an average of 10.5 pounds (4.8 kg) in 6 months, or roughly 2.5 pounds (1.1 kg) per week.
  • Diet adherence was difficult for the participants, making weight loss difficult to maintain.
  • The majority of experts concur that 1-2 pounds (0.45–0.9 kg) of weight loss per week is healthy for the body.
  • for the majority of people, so long as they can eat a variety of foods and do not feel deprived.

On their website, SlimFast states, “Give us a week, and we’ll take off the weight.” That’s a big claim, and according to their marketing materials, their Quick Start program can help you lose up to 5 pounds (lb) in the first week.
That may sound exhilarating, but experts advise being cautious.
The program claims that by using this method, you can lose a safe 1 to 2 pounds per week.
People often blame diets for their short-term weight loss and long-term weight gain, among other things. This is where SilmFast is right now.

Short-Term Effects

Being on the SlimFast program will result in weight loss shortly. You consume 1,200 or 1,600 calories each day, depending on your gender. However, “those who lose weight rapidly gain it back rapidly.”

Long-Term Effects

Because there are few possibilities for meal replacements, you won’t want to continue with the SlimFast regimen in the long run (and with the flavors and textures). SlimFast suggests continuing to substitute a SlimFast shake, bar, or cookie for one meal a day even after you reach your weight-loss goal.

This indicates that the plan includes continuing to use SlimFast products over the long term. If you haven’t figured out how to cook nutritious meals, you can resume your old eating habits, which could lead to weight gain.
Furthermore, experts are unsure if SlimFast will support long-term weight loss.

How much weight can you lose in a week with SlimFast?

1 to 2 pounds per week

On the Slimfast diet, you eat two Slimfast meal replacements, three 100-calorie snacks (like Slimfast snack bars, fruits, vegetables, or even nuts), and one 500-calorie meal you make yourself. Using this method, you can eat six times per day. According to the program, you can safely lose 1 to 2 pounds per week using this method.

With SlimFast, how much weight can you lose in a month?

Clinical studies have shown that the SlimFast Plan can help people lose between 1 and 2 pounds each week. 1,200 calories for women and 1,600 calories for men are the daily caloric restrictions for the program..

How long does it take to lose 20 pounds on SlimFast?

Eight to 10 weeks

The best results from SlimFast come from those who need to lose around 20 pounds, which should take eight to ten weeks. 

Longer-term adherence is likely to be difficult for most people. Even so, many people who have lost weight use SlimFast products as sporadic meal replacements to help them keep it off.

Does SlimFast help you lose weight?

Yes, Slimfast can help you lose weight. People who don’t want to track calories can benefit from structured programs like this one. According to studies, eating portion-controlled meals or meal replacements helps people lose more weight.
Weight loss is encouraged by low-calorie diets like the Slimfast diet or the consumption of one or two meal replacements, which can also help you keep the weight off longer.

Slimfast only diet

Some people may ask, “Can I just drink SlimFast to lose weight?” Can I replace all meals with SlimFast? However, that might be a very bad idea because of the following reasons:

This could lead to starvation

If you only eat SlimFast shakes for breakfast, lunch, and dinner, you will only take in 540 calories each day. overtime

That diet is regarded as starvation food. Michigan Medicine says that a very low-calorie diet (VLCD) of less than 1,000 calories per day often doesn’t give you enough nutrients and shouldn’t be done without a doctor’s supervision.

Increase the risk of health problems

When you don’t eat enough calories, you may not get enough of certain nutrients. This can lead to serious, even life-threatening problems. 

People on very low-calorie diets often:

  • Feel tired most of the time 
  • Have trouble going to the bathroom
  • Get sick frequently
  • Have diarrhea, gallstones are another risk. 

May hinder weight loss

if your body is trying to save energy, depending only on SlimFast diet products gives you too few calories,  which will slow down your metabolism.


You could have thought about drinking seven to ten shakes every day to get enough calories. That is also a potentially risky option. 

Some of the vitamins and minerals in SlimFast diet smoothies can hurt your health if you take in too much of them.

Iron accumulation

For example, if you drink eight SlimFast Keto smoothies per day, you’ll get 48 milligrams of iron.
If you use SlimFast products more often over time, you may end up with more iron in your blood.

The National Institutes of Health says that getting more than 20 milligrams of iron per day from supplements and fortified foods can cause:

SlimFast app

A fairly new app called SlimFast Together is offered by the company to help you stay on track and reach your weight loss goals. You can use this app for these points:

Taking a quiz to know which plan fits you

When you first use the Slimfast diet app, you have to take a 5-minute quiz to find out what you like and what your goals are.

To grab ready-made meal plans and recipes

After that, you may use the app to plan meals by choosing from already-approved recipes or adding your own. 

To track your progress

You may use the app’s built-in calculator to see whether you’ve reached

  • Your daily caloric
  • Daily macronutrient
  • Hydration objectives
  • Exercise
  • Stress

To order your grocery

Probably the most practical function is the ability to order groceries. 

You may order groceries for delivery or pick up from a nearby supermarket, and it automatically creates a shopping list based on the items on the menu.

Is the slimfast app free?

SlimFast Together is currently available for free download on Apple and Android devices.

What are the downsides to SlimFast?

You might be wondering if Slim Fast is bad for you.

Unfortunately, that’s true, the SlimFast diet has its downsides, so, let’s discuss what the side effects are of drinking SlimFast shakes and replacing them with some daily meals.

Low-nutritional value

From the perspective of some experts, the plan doesn’t include enough real food. You do not benefit from having whole foods at every meal and snack when following the SlimFast diet.

This way, you might miss some nutrients you take naturally when you consume healthy regular foods.

SlimFast products are highly processed

A lot of the food products in this diet (shakes, bars, and snacks) are heavily processed.
After eating, some people might not feel satisfied. 

The ultra-processed SlimFast products have added carbs, isolated fiber (which is a fiber that has been added to food in a lab), protein powder, and other substances that were made in a lab.

Not everyone will find the SlimFast plan to their liking. 

Can cause weight gain

Some people, according to experts, may overeat SlimFast bars and gain weight. Some people, according to experts, may overeat SlimFast bars and gain weight.

 Additionally, if you consume a lot of shakes, you might not feel full because you aren’t chewing your meal.
Boredom could happen. It might become tedious, like with any meal replacement product.

There aren’t many options for the shakes, bars, and snacks, though you can mix up your free meal and snack to provide variation.

Not all products are tasty

Drinking smoothies or munching chips lacks flavor, in addition, you might get bored.

Also, not all flavours are delicious as not all of them contain sugar.  

It may become costly

The SlimFast diet requires many doses of drinks and snacks each day. According to Blatner, they are more expensive than produce.

This diet has few calories

Even if you’re trying to lose weight, your body requires calories to stay nourished and energized, and that’s just for the bare necessities.

Even if you’re trying to lose weight, your body requires calories to stay nourished and energized, and that’s just for the bare necessities.

With very low calories, it can be difficult to stick to exercising daily. It will be excessively restricting, and its daily activities will be challenging. 

However, you have to consult your physician for medical supervision if you’re determined to use SlimFast.

  • Diets with 1,200 calories are usually only good for older women who are very small and don’t do many activities. 
  • Young adults who work out often, have physically demanding daily activities than average, so 1,200 calories isn’t enough.

Doesn’t support lactose-free diet

Because the majority of SlimFast products have milk as their main ingredient, people with lactose intolerance, milk allergies, or people who restrict dairy products for other reasons won’t be able to follow this plan.

Frequently asked questions

Why am I gaining weight on SlimFast?

You may notice you are gaining weight on the SlimFast diet rather than losing it for the following reasons:

  • You are still starting, and you need more time. In this case, relax, and don’t panic if you don’t lose anything for a week or two. It is usually just your body getting used to the weight loss regimen. The body frequently maintains water balance while still losing fat.
  • SlimFast products are made of non-organic whey protein, which is inflammatory and, when metabolized, turns into sugar. 

The remaining ingredients are made up of preservatives, chemicals, and sugar, all of which might cause weight gain.

Does SlimFast work without exercise?

You should unquestionably exercise on the SlimFast plan. If you incorporate at least 30 minutes of activity each day into your weight-loss strategy, you’re more likely to lose weight faster, feel more energized, and keep it off permanently. 

There’s no need to worry if you don’t have enough money or time to attend a gym.

  • You can increase your endurance by walking every day before trying out other sports.
  • Finding an activity you enjoy is the best approach to continue exercising consistently. 
  • Cycling, swimming, or even dancing doesn’t require anything to start.
