What Exactly Is SlimFast?
SlimFast is an app-based weight-loss program that focuses on meal replacement shakes, bars, and snacks as a main cheval.
It’s been around for a long time, and almost every one of my customers has tried it at some point throughout their weight-loss journey. It was one of the first meal replacement diets to be developed.
SlimFast was formed in 1977 and began by selling meal replacement weight-loss smoothies.
They’ve recently extended their product line to include meal replacement shake mixes, prepared shakes, bars, and snacks that cater to a variety of dietary needs.
SlimFast promises to help you lose 1–2 pounds every week, according to their website.
Two of your daily three meals must be meal replacements according to the SlimFast diet plan. A “reasonable” (500–600-calorie) quantity of actual food should be your third meal.
Three snacks each day, such as SlimFast products or other 100-calorie healthy snacks, are also recommended by the SlimFast program.
The SlimFast Diet in Action
SlimFast is a calorie-counting app that provides meal replacements, low-calorie recipes, and tools to measure your progress.
Depending on your preferences, the SlimFast program provides four alternative diet plans.
- SlimFast Favorite Foods: This plan is the most adaptable, since it is meant to work with any eating pattern, including low-carb, high-protein, and vegetarian diets. This plan allows you to eat anything you want.
- SlimFast Keto: This plan is for those who are on a ketogenic diet. The dishes and products adhere to the keto diet’s low-carb, high-fat guidelines. SlimFast, for example, sells “keto bombs,” a snack made specifically for this diet.
- SlimFast Original: This plan is meant for those who wish to reduce weight while sticking to the original SlimFast products.
- SlimFast Diabetic Weight Loss: This strategy, together with its meals and SlimFast products, is for those who desire to live a low-carb diet while also controlling their blood sugar levels. This eating plan might benefit from the Keto or Diabetic Weight Loss SlimFast products.
If you’re not sure which diet plan is right for you, the SlimFast website has a 5-minute questionnaire you may complete.
After you’ve chosen your plan through the app, you’ll be asked to customise it. SlimFast products may be used for all of your meals and snacks, as well as your one regular meal.
The SlimFast Together app is used to make all of their choices, monitor their progress, and plan meals.
You may accomplish the following using the SlimFast Together app:
-
Plan and prepare your weekly meals. You may choose from one of their SlimFast recipes or create your own from scratch. You’ll be able to see the calorie and nutrient information of the meals you choose or input so you can make sure they fit within your diet.
-
Monitor your progress. You may follow your progress toward your objectives using the “Progress” tab, which is based on the information you submit. You may keep track of your weight, body measurements, food and water consumption, exercise, sleep, and stress, as well as snap images to document your progress.
-
Use instructional resources. SlimFast’s licensed nutritionist provides unique blog and instructional material.
-
Keep yourself on track with reminders and inspiring texts.
-
Share your culinary creations with family, friends, and followers on social media.
When you achieve your target weight, you should switch to the SlimFast Maintenance Plan.
One SlimFast meal replacement product, two reasonable 500–600-calorie meals, and three 100-calorie snacks are included in this diet.

Questions Frequently Asked
What Exactly Is SlimFast?

What are your thoughts on SlimFast meal replacements?
Although some of the original chocolate and vanilla shakes are said to be tasty, several of the additional items have received negative feedback from customers.
Is it necessary for me to keep track of my calories on SlimFast?
Will SlimFast aid in my weight loss?
According to certain studies, meal replacement methods like SlimFast may help you lose weight quickly. They may, however, be difficult to maintain in the long run.
Is it necessary for me to purchase SlimFast goods, or can I just follow their recipes?
You must eat at least two of SlimFast’s meal replacement products every day to be a member. You just need to ingest one SlimFast product per day after you’ve reached your weight-loss target and are on maintenance.
I dropped weight on SlimFast, but I’m worried about regaining it. What can I do to keep it off?
You must maintain your weight loss by following a nutritious diet and exercising regularly.
Continue to monitor your diet and exercise habits in the app for a time to ensure you’re not going over your calorie limit or reverting to old habits.
Make a friend, family member, or health care provider accountable.
Foods to Eat and Stay Away From
On SlimFast, there are no items that are completely off-limits. However, depending on the eating plan you choose, the kind of foods that are advised for your one meal a day may differ.
Depending on your objectives, calorie recommendations vary from 1,200 to 1,600 calories per day.
Depending on where you are on the SlimFast regimen, you are permitted three 100-calorie snacks per day and one to two 500–600-calorie meals.
Some of SlimFast’s meals are rather healthful and nutritious, while others are sodium-laden. Because salt holds water, too much sodium in the diet might make it difficult to lose weight.
On the SlimFast regimen, this is a one-day example menu:
- SlimFast Shake for Breakfast
- Snack in the morning: a 100-calorie snack of your choosing
- SlimFast Protein Bar for Lunch
- Snack in the afternoon: 100-calorie snack of your choosing
- SlimFast Sensible Dinner Recipes
- SlimFast Crisps (evening snack)
Is It Effective in Weight Loss?
There are a few research on meal replacement programs like SlimFast and weight reduction, but the most of them are old.
This might be due to the fact that meal replacement programs are less popular now than they were in the early 2000s.
For example, a 2006 research looked at the efficacy of four popular diet regimens, including SlimFast, in 293 adults with a BMI of 27 to 40 over the course of six months.
After six months, participants in the SlimFast group had dropped an average of 10.5 pounds (4.8 kg), or 4.9 percent of their body weight. The first six months were when the most weight was lost.
Over the course of a year, the SlimFast group maintained their weight reduction, whereas the other group gained 1.3 pounds on average.
However, it’s worth noting that 29% of the study’s participants left out because they couldn’t stomach the diet, and just 9 of the initial 58 people were able to stick on the diet for the whole year.
Another research from 2004 had 63 people who used SlimFast meal replacements for six months. On average, these individuals dropped 7% of their body weight.
However, since some of the research were supported by SlimFast, a more recent evaluation found a significant chance of bias for SlimFast trials.
Meal replacement methods like SlimFast, according to a review of the studies, may help you lose weight in the first 3–6 months.
The concern is whether the diet can be maintained for much longer, as indicated by the significant dropout rate in SlimFast research.
Meal replacements are not a healthy approach to lose weight, according to me, a registered dietitian specialized in weight reduction.
This is due to the fact that meal replacements are just a band-aid solution that does not educate you how to eat correctly. They’re also not necessarily as full or gratifying as a traditional dinner.
Learning to consume and prepare nutritious meals, as well as addressing lifestyle obstacles such as emotional eating, stress, and sleep, are all necessary for long-term weight reduction.
Summary
Meal replacement methods like SlimFast, according to some study, may help you lose weight in the short run over 6 months. However, you run the danger of regaining weight if you stop the regimen.

Sustainability
The SlimFast diet is simple to follow at first since it eliminates the guesswork from eating.
If you don’t want to spend a lot of time preparing meals or deciding what to prepare, having your meals planned for you could seem intriguing.
You just have to worry about supper since two of your three meals are SlimFast products.
However, consuming shakes and bars might get repetitive after a time, and doing so does not teach you how to eat properly.
This is supported by the findings of the SlimFast research, in which 29 percent of individuals dropped out due to inability to keep to the diet.
In my weight-loss clinic, I’ve seen this far too many times when people conclude that all they need to do is learn how to cook genuine food in a simple manner.
Summary
SlimFast may be maintained for a few months since the meal replacements eliminate the guesswork of eating. Most individuals, however, do not wish to drink shakes and consume bars for an extended period of time.
Accountability
One of the most important advantages of a weight-loss program is accountability, which keeps you on track and motivated.
You get access to a secret Facebook community after buying a SlimFast package. If a group environment stimulates you, this might be useful, depending on the size of the group.
A qualified dietician who develops instructive films, blogs, and meal ideas is also available as a consultant.
There is no specific counseling or accountability, and the nutritionist is not accessible for one-on-one assistance.
SlimFast is unsuitable for someone who wants a more customised strategy according to their requirements and lifestyle. If you don’t think you need that much responsibility, the private Facebook group can suffice.
Summary
SlimFast promotes accountability via a Facebook community as well as educational tools. There is no one-on-one responsibility.
Cost
Slimfast’s overall cost varies based on the sorts of items you buy and how much you buy.
The cost of the needed two SlimFast products each day is often above $100 per month. The price may be greater if you want snacks on top of that.
Signing up for Auto Delivery gets you a 12 percent discount on any goods. You may choose to have things delivered monthly or once every nine months.

Starter Kits and Bundles for SlimFast

- $69.99 for a 14-day low-carb starter kit
- $89.99 for a 14-Day Keto Starter Kit
- $149.99 for the SlimFast Together Starter Kit
- Bundle of Low Carb Bars & Snacks: $24.96
Safety
SlimFast products are generally safe for most individuals, but anyone with milk, soy, or peanut allergies should avoid them since many of their products include these components.
One thing I observed is that the nutrition label for SlimFast products does not contain saturated fat. However, the overall fat level is considerable, which might raise the risk of health concerns such as heart disease over time.
SlimFast is also not a diet product that I would suggest to anybody with a history of disordered eating, since it is a diet product that might trigger eating disorder behaviors.
What It Compares To
There are other meal replacement diet regimens available, but the HMR program is the most comparable to SlimFast (Health Management Resources).
HMR, like SlimFast, mandates that you buy their goods as part of your regular routine.
HMR sells meal replacement smoothies as well as frozen meals including penne spaghetti with meatballs and chicken enchiladas.
There are no minimum requirements for any program, and you may cancel at any moment.
The HMR program includes an initial medical assessment before beginning, which adds to its credibility.
SlimFast does not provide weekly coaching calls and does not give further 1:1 accountability.
The calls, however, are with a health coach rather than a qualified dietician. A health coach may give encouragement and support, but they are not necessarily able to provide more precise, tailored advice.
The HMR treatment costs roughly $100 every week, while SlimFast costs $100 per month. However, you will get a medical consultation, frozen meal replacements and smoothies, as well as weekly calls.
Still, most health experts, including myself, believe that any meal replacement program is just not as healthy or enjoyable as one based on actual food.
In conclusion
While the SlimFast Diet may lead to short-term weight reduction, research suggests that it is unlikely to last more than six months for most individuals.
When individuals quit following it, they often gain weight. Almost all of my customers who have come to me after following it have experienced this.
The main reason for this is because the SlimFast program does not teach the fundamentals of appropriate eating, and as a result, many individuals ultimately seek more actual food.
If you’re having trouble losing weight, talk to your doctor about the best plan for you.
Steps to Follow
If you want to reduce weight, I recommend eating a low-calorie, well-balanced diet rich in delicious genuine food.
Learning how to create nutritious meals is a lifelong skill.
One easy way to get started is to attempt two new healthy meals each week, making enough for leftovers so you don’t have to cook every day.
Additionally, regular exercise, stress reduction, and excellent quality sleep are all things that will help you lose weight for the rest of your life.
Seek the advice of a licensed dietician who can build a more specific weight-loss strategy for you to keep motivated and on track.
Having a close family member or a like-minded friend to hold you accountable might also help you stay motivated.
Noom might help you lose weight.
Noom is a tried-and-true weight reduction method that uses psychology and teaches you how to eat to meet your particular health goals and levels. Begin by doing a simple examination to see which option is best for you.
The “slim fast weight loss in a month” is a diet that claims to help users lose weight quickly. The diet includes low-calorie meals, shakes and bars.
