We’re hearing a lot of buzz about Slim Fit. We took a closer look at ingredients, side effects, clinical research and customer service quality. Additionally, we examined hundreds of customer comments and reviews. Then, we summarized and refined to give you the info you need.

Slimfit Readers: Click here to find out why we're giving away samples of our product, Leptigen.

What is Slim Fit?

First off, Slim Fit is a weight-management program consisting of healthy eating and exercise. [1] After following for a minimum of 30 days, you supposedly lose weight and improve overall wellness. One of the benefits is the plan is customized to your fitness level.

There’s no mention of when Slim Fit was introduced, but the person who created it, Derek Kuryliw, is a certified sports nutritionist – impressive. You can only sign up for the program on the official website or by visiting the training center. We like that we located some favorable customer comments and the plan emphasizes healthy eating practices, but read on…

Slim Fit Ineffectiveness – “No Results?

The first concern was the ineffectiveness of Slim Fit. “A weight-loss program with specific details could possibly help with weight-loss,” said our Research Editor. “But the real test of a plan is how dieters feel after the initial days, 30 days.”

“After three months, I haven’t even lost a single inch,” stated a consumer.

“I gained weight instead of losing. I tried two different times,” said another.

Some dieters noticed results and wanted to continue after the 30 days. “I haven’t missed but a few days since I started, it’s addicting,” stated a customer.[2]

Customer Service Quality – “Poor Service?

Based on customer comments, the Slim Fit customer service wasn’t the best. “I called and called but never got a call back or anything. I can’t believe that is the way they do business,” said a consumer.

“After so many calls made to the company, they didn’t refund my money,” reported a customer.

While some didn’t care for the customer service team, we found that others received support and answers to their concerns.

“Every time I’ve been there the staff has been helpful,” said a user.

“I have never met more motivating and kind people in an environment like this before,” said another.

What we’ve found was that all it takes is something deemed concerning, like poor customer service quality, to reduce the chances of long-term success. If the Slim Fit team doesn’t respond well to customer complaints, it might not be the best fit for dieters.

The Science – “Solid?”

While we’ve found research into healthy eating and fitness, there’s no published clinical research proving Slim Fit will help you lose weight. At DietSpotlight, science is a critical part of the research process. If there are no studies, we become hesitant. [3]

The Bottom Line – Does Slim Fit Work?

Here are our final thoughts on Slim Fit. Well, we like that we located some favorable customer comments and that the program seems affordable, but we have concerns about this one because there’s no research showing it works. We’re also hesitant about it because customers are concerned the program doesn’t work and the customer service team isn’t helpful.

If you want to lose those extra pounds, we suggest going with a supplement containing some clinically-tested ingredients, supported by a customer service team willing to help resolve concerns.

Among the best products we’ve seen this year is one called Leptigen. The supplement contains some clinically-tested ingredients and has been shown to help boost metabolism and ignite fat loss. Customers are talking about seeing excellent results and no one is chattering about negative side effects.

Also, the company behind Leptigen is so confident in their supplement, they’re offering customers a Special Trial Offer – a great choice.

Slim Fit: What You Should Know

A lot of people invest good money in weight loss supplements and diet programs. In fact, there are currently hundreds of diet programs out there all claiming to have the secrets to being slim and sexy. On the Internet alone you’ll find myriads of diet programs aimed at effective weight loss. The Slimfit Diet Program is one of these. Created by a guy named Derek Kuryliw, the Slimfit Diet program claims to offer a unique approach to dieting and fitness. Kuryliw, according to their website is a sports nutritionist based in Florida. In our opinion though, a bit more information about the founder would have added more credibility to his name. But unfortunately, this same scenario applies to most of the website. The site says that Slimfit is a revolutionary program which can transform both a person’s body and mind, improve overall health and appearance and increase total energy. The problem however is that nowhere in the site can one find exactly how the program plans to do these things. Further exploration into their site shows a bevy of videos on weight loss tips and tricks as well as a list of the program’s promises and claimed benefits. One of the benefits includes losing around 15 to 20 pounds within just the first month of trial. They also mention that participants need only to diet for 5 days a week with specific cheat days in between. The manufacturers have also included a list of other products which they say are exclusive to the Slimfit product line. These are Trim Fit, Hunger Strike and PROfit. The three products are said to minimize food cravings, improve metabolism and remove unwanted fat and other elements from the body. Enrollment in the Slimfit Diet Programs starts at $99.

Slim Fit Ingredients

Other webpages mention that the Slimfit programs uses a combination of exercise, diet and supplementation to help clients shed pounds. They say that the key is based on the personally tailored diet plan that will accelerate one’s metabolism in order to burn fat. In addition to this, the Slimfit diet program offers online counseling, Q&A sessions with fellow dieters , as well as diet tips from founder Kuryliw.

Product Features

Slim Fit Advantages

  • Claims of increased metabolism and overall good health
  • Testimonials from supposed clients and customers
  • Info from their blog, Facebook and various online support sites

Slim Fit Disadvantages

  • Lack of sufficient information for potential clients
  • Vague and usual benefit promises
  • Needs more info about its founder
  • Expensive


When looking out for a specific diet plan or fitness program, we strongly suggest requesting for specific details on how they plan to deliver on their promises. The Slimfit diet program offers pretty enticing results, but the lack of concrete information should make you consider checking out other programs too for comparison first.

Slimfit Side Effects:

Although the actual weight-loss benefits of Slim Fit are unclear, most people have no negative effects to report. However, there are some reported cases of side effects.


Sleeplessness, or insomnia, can make you feel horrible. You find it hard to fall or stay asleep at night. You toss and turn in bed, struggling with stress and perhaps even pain. During the day, the fatigue makes it hard to go about your daily routing. You feel on-edge.

What causes sleeplessness?

Sleeplessness is a common symptom of many different conditions. Asthma, arthritis, allergy, and certain neurological disorders are common culprits. Sleeplessness also occurs due to poor bedtime habits. Eating too late at night and consuming too much caffeine, for instance, make it harder to get a good night’s sleep.


When you’re dizzy, you feel light-headed and weak. Your balance is impaired. You’re on the verge of blacking out. You may faint or stumble.

What causes dizziness?

Many people become dizzy because of a sudden drop in blood pressure or blood volume. Hypoglycemia, or low blood sugar, is also a common cause. [1] There’s also motion sickness. Getting on a boat when you’re not used to the motion is likely to make you dizzy. Heat stroke, dehydration, and anxiety disorders all contribute to dizziness.


A piercing headache can take a lot out of you. Really bad ones, like migraines, feel like someone took a sledgehammer to your head. It’s an acute piercing sensation coupled with a feeling of tightness. The immense pain of severe headaches can lead to dizziness.

What causes headaches?

Most headaches are easily treatable. They’re the result of stress, hunger, tiredness, or over-exposure to the sun. In some cases, headaches can be indicative of an underlying condition such as glaucoma, aneurysm, and concussion.

Stomach Pain

Stomach aches can be very painful. It’s not uncommon for you to simultaneously experience bloating, nausea, fever, and dizziness when your stomach hurts. [2]

What causes stomach pain?

Indigestion is one of the top causes of stomach pain. You may have eaten something that didn’t sit well with you, either because of food intolerance or food allergy. You may have contracted a stomach virus or bacteria. Or you may be suffering from pelvic inflammatory disease. Kidney stones are also known causes of stomach pain, as is constipation.

Slim Fit may cause side effects in some users, depending how your body reacts to the pills. If you have any health concern, talk with your doctor.

Slimfit Ingredients and Supplement Facts

Other Ingredients: None

We examined Slimfit Program ingredients in order to give you the information you need.

Strength Training

Strength training, also known as resistance training, is a group of exercises meant to help one increase lean muscle mass and decrease fat in the body. Most of the time, it involves the use of weights. [1]

What Is It Supposed To Do?

Strength training is supposed to help increase lean muscle mass while decreasing the amount of fat in the body. It can also help strengthen the bones, manage weight, manage chronic conditions, and sharpen thinking skills.

Clinical Research

According to a study published in Current Sports Medicine Reports, “Resistance training may be effective for reducing low back pain and easing discomfort associated with arthritis and fibromyalgia and has been shown to reverse specific aging factors in skeletal muscle.” However, nothing in this research noted any weight-loss effects associated with strength training, however we do know that exercise increases metabolism.

You may want to try Leptigen, a weight-loss supplement that has clinically tested ingredients. You can add it to your exercise program to maximize weight-loss.

Cardio Exercises

Cardio exercises are ones that increase heart-rate. Examples include running, jogging, high knees, jumping jacks, and squat jumps.

What Is It Supposed To Do?

Since cardio exercises focus primarily on increasing the heart rate, a lot more calories are burned. This can help aid in weight-loss and improve heart health. [2]

Clinical Research

According to a study published in Obesity (Silver Spring), “Supervised exercise, with equivalent energy expenditure, results in clinically significant weight loss with no significant difference between men and women.” However, without knowing what kinds of cardio exercises are included in the Slimfit program, we can’t be sure this is the case for their users.

Repetition Training

Repetition training, also called interval training, involves repeating certain exercises for short periods over an extended length of time. For example, you could do four different workouts for 20 seconds each, and then repeat it eight times.

What Is It Supposed To Do?

Repetition training is a good way to increase health and help you lose weight. It is often practiced by those who have a higher fitness level.

Clinical Research

In a study published in the Journal of Obesity, researchers compared the weight-loss effects of aerobic exercises versus high intensity interval training. In their conclusion, they wrote, “Overall, the results from this study show that continuous aerobic exercise training is effective for improving fat distribution independently of weight loss, but the HIIT intervention employed did not improve fat distribution.”

Healthy Eating

Generally, “healthy eating” includes a balanced diet of protein, carbohydrates, and fat. It also includes the needed nutrients, vitamins, and minerals for the body.

What Is It Supposed To Do?

Healthy eating can improve health and jump start weight-loss.

Clinical Research

According to a study published in the Journal of the Academy of Nutrition and Dietetics, “Increasing fruits, vegetables, and low-fat dairy may help achieve weight loss and maintenance.” The Slimfit program only promotes healthy eating though, and choices individuals make will affect their weight-loss.

Is There Anything Out There That TRULY Works?

One of the best products we have seen this year is Leptigen. With clinically tested ingredients, a supporting customer service department, and users raving about the results they are seeing, we think this is the one for you.
