    Individual Goals

    More than 31 percent of adults in America today are obese, and 48 percent believe this is the result of their diet.1 They state that their biggest reason for losing weight is to improve their health. Teens and adults alike seem to recognize the importance of following a healthy diet. Teens say they follow a specialty diet for health-related reasons, while 62 percent of adults say they would like to eat plant-based foods to help manage their weight.2 Using the Suddenly Transformation Weight Loss Program can help with these goals, which is why many individuals choose to use this program.

    Weight and Its Role in Overall Health

    Weight plays a significant role in a person's overall health. The CDC reports modest weight loss, even as little as five percent of total body weight, can provide several health benefits. Blood pressure, blood sugar, and blood cholesterol all improve.3

    Men and women who are obese are more at risk of certain types of cancer, type 2 diabetes, heart disease, and stroke. In the United States, approximately $147 billion is spent annually on medical costs for those who are obese when measured in 2008 US dollars. Obese individuals spend roughly $1,429 more on medical care each year than those who are of normal weight.4

    Suddenly Slim Weight Loss Products

    Each program is made up of individual products. These products are described in more detail below and can also be purchased individually, or in addition to, the Suddenly Slim programs.

    First Fitness Reneu body and colon cleanse for cleansing and detoxification
    100 Vegetarian Capsules

    Reneu Inner Body & Colon Cleanse

    Supports cleansing and detoxification of inner body and colon to help enhance absorption of food, vitamins, and minerals and optimize weight loss.*

    Toxins in the body or bacterial imbalances often inhibit a person's ability to lose weight. In fact, they can be the main reason a person struggles to take off excess pounds. Reneú may be of help in overcoming these challenges, removing the toxins, and balancing bacteria in the intestinal system.

    Reneú helps the body absorb food, vitamins, and minerals while optimizing weight loss. It does so by cleansing and detoxifying the colon and inner body with the help of all-natural substances. When the intestinal system is cleared of impurities, it can take in more of what humans need. As a result, health and wellness improve.

    Furthermore, individuals who use this product find they experience less abdominal bloating. The waistline looks slimmer because it is no longer swollen due to the bloating. However, this product works best when used with other products in the FirstFitness Boost, Accelerate or Transformation Weight Loss Programs.

    First Fitness XanoLean Supreme helps smooth cellulite
    90 Vegetarian Capsules

    XanoLean Supreme Maximum Strength Weight Loss

    A powerful nutrient-rich herbal formula designed to help curb appetite, reduce belly fat, promote the fat burning process, and increase energy.*

    Cravings are the downfall of many diets. When a person has a craving for sugary, fatty or salty foods, the temptation may simply become too great. When this individual gives in to the craving, he or she often overindulges and undermines all weight loss efforts. XanoLean Supreme is of great help in ensuring this does not happen.

    XanoLean Supreme plays an important role in the FirstFitness Nutrition Transformation Weight Loss Program. Not only does it help to curb a appetite, but it also boosts energy and promotes the burning of fat. The use of this product activates the pleasure centers of the brain that are stimulated when salty, fatty, or sugary foods are consumed. The cravings become a thing of the past.

    This is only one of the ways XanoLean Supreme helps with weight loss. It also increases the cellular thermostat that burns fat for use as energy. The nano-sphere delivery system increases the absorption of the ingredients so weight loss occurs more rapidly.

    First Fitness Body FX meal replacement shakes contain protein, essential vitamins and minerals
    14 Servings

    Body FX Meal Replacement Protein Shake

    Contains 13 grams of whey isolate protein, 22 essential vitamins, minerals, fiber, antioxidants, and phytonutrients for balanced nutrition.*

    Skipping meals is never wise when you are trying to lose weight. Fortunately, you don't have to. Choose Body FX meal replacement protein shakes and you get a nutritional meal replacement protein shake that is time-released and specially formulated for weight loss. This delicious shake features a balanced macronutrient ratio to ensure your body gets exactly what it needs. It contains 50 percent low glycemic carbohydrates, 30 percent protein, and 20 percent fat, making it ideal for breakfast, lunch, or dinner.

    The Body FX shake contains essential vitamins and minerals while satisfying your urge to eat. The shake is a blend of casein protein and whey and allows the body to digest and release nutrients quickly and over a period of time. The nutrition and fiber found in the shake make it ideal for individuals of any age.

    As you feel full for a longer period of time, you won't eat as much. Your blood sugar level stabilizes and the pure crystalline fructose used in the shake produces a glycemic index response that is lower than what is seen with traditional carbohydrates. The fiber contained in the shake likewise slows the glycemic index response. The shake also provides phytonutrients and antioxidants to ensure a complete meal in one delicious drink.

    First Fitness Nutrition Tribolic with vitamins and minerals helps to smooth cellulite
    30 Servings

    Trimbolic Fat & Cellulite Fighter

    Contains dietary fibers and botanical extracts that help satisfy appetite, smooth cellulite, and support lean muscle tissue while losing weight.*

    For those times when you don't want a shake or a full meal replacement, Trimbolic is available. This drink contains dietary fibers and botanical extracts that promote weight loss. With this drink, your appetite is satisfied and lean muscle tissue is supported even as you drop excess pounds. Additionally, cellulite is smoothed when you consume this drink.

    Anyone looking to lose excess weight or decrease body fat should consider making use of the Transformation Program. Those who have tried this program find it is the solution they have been looking for to take off the weight and get into better shape. Try it today and see how it benefits you.

    Weight Loss Success at a Healthy Rate

    If you’re like most people who want to get rid of extra weight, you want to see results fast. It can be more difficult to stick with a diet of any kind if you don’t see results pretty quickly, and that’s normal. While weight loss should be slow and steady with Suddenly Slim, at first, you might see a more rapid reduction in weight.*† After you’ve lost some weight, the weight loss might slow down or you might plateau for a little while.5 However, that’s nothing to worry about because you are still eating healthy, so the weight is still coming off even if it’s slowly, and it’s disappearing at a healthy rate for your body. With Suddenly Slim, you can get to where you want to be.

    The Obesity Issue in the United States

    The United States ranks number one in the world for obesity. Between 2015 and 2016, nearly 40% of adults in the US were obese, with 7.6% being severely obese.6 Another almost 32% of adults were overweight. Over the last several decades, obesity rates have increased throughout the population groups within the United States. The cause can be linked to a few different issues, though the main culprits are an abundance of unhealthy food options and many adults simply not knowing how to eat properly.

    In the US, there are plenty of restaurants as well as fast food places to go to eat. When someone is busy, fast food often seems like the easiest option because they don’t need to spend an hour cooking and can feed the whole household. This becomes an issue when it’s the dinner – or breakfast or lunch – of choice far too often. The cheap food might taste good, but it’s filled with empty calories that are going to just increase a person’s weight.7

    Along with this, many Americans simply don’t know what a healthy diet looks like. Statistics show that many people in the US do not eat enough vegetables, don’t have a very varied diet, and don’t make the right choices for food when they do eat at home. It’s far easier to simply grab an unhealthy snack than to take the time to make something, and it can seem less expensive as well. All of this together has created an epidemic of obesity within the country, one that’s difficult to get away from.

    What Obesity Can Cause

    Being overweight or obese can lead to a host of other issues. The human body is not designed to hold onto all of the extra weight that occurs when someone gains too much weight, whether it’s from a poor diet or from other issues. Obesity can lead to high blood pressure, heart disease, diabetes, and more. It can also lead to an increased chance for someone to have cancer.8 Many people who are overweight also report higher levels of stress and anxiety, as well as pain and inflammation.

    When someone is significantly overweight, their body is unable to handle it well. It stresses out everything else inside the body, from the bones and joints to the heart and digestive system. This is why people who are overweight tend to have more medical issues compared to those who weigh a healthy amount. The good news is, however, that a lot of the issues that someone who is obese may suffer from can be reduced by losing weight. When the weight is kept off long-term, they can decrease the health issues and, in some cases, find complete relief from the issues they had when overweight.

    Benefits of Losing Weight in a Healthy Way

    If you’re looking to lose weight, the obvious immediate benefits are that you’ll look better, feel better, and fit into your clothes better. However, none of this will last if you are thinking diet pills alone are the answer. You must gradually make some healthy lifestyle changes to lose weight and keep it off. Some of the benefits of losing weight in a healthy way include the following.

    • Ability to Keep Weight Off – When you lose weight in a healthy way, you learn how to eat better, which enables you to keep the weight off. There’s no more worry about the pounds piling back on or you having to start a new diet just to get your weight under control again.
    • Ability to Enjoy New Activities – When the weight is off for good, it’s possible to participate in new activities that might not have been possible with the extra weight. With joints that feel better, this can be as simple as being able to spend more time in the garden, being able to exercise and go on a run, or just being able to do activities without the anxiety that the extra weight will make it difficult or impossible.
    • Ability to Reduce Health Issues Permanently – Weight loss that is long-term can help reduce the weight-related issues that those who are obese have.9 If you’ve had issues with your joints because of the extra weight, losing it can help you feel better and reduce the pain significantly. This can have a profound change in your overall health and how you feel each day.
    • Ability to Improve Self-Esteem – When you lose weight, your self-esteem tends to improve significantly because you feel better about your body and yourself. When the weight loss is done in a healthy way and is sustainable, you’ll continue to see improved self-esteem.

    Why Most Diets Don’t Work

    Sustainability is the number one reason why most diets don’t work. Of course, they help people lose weight quickly. If the weight doesn’t stay off, however, it was all a waste. Most diets are designed to encourage rapid weight loss, often by using techniques that are hard on the body and simply can’t be sustained for long.10 A soup-only diet, for instance, can help take a significant amount of weight off, but no one can just live on soup for the rest of their life.

    When a diet isn’t sustainable and isn’t something that can be done long-term, the weight is just going to come back when the person goes back to the way they were eating before the diet. Of course, many people do try these diets with the idea that they’ll completely change how they eat once the diet is over and they’ll be able to keep it off. The problem is, they haven’t done any of the work to change their habits and will end up quickly reverting to what they used to eat, gaining the weight again.

    A Change in Lifestyle is Required

    When someone wants to lose weight and keep it off, they need to change their lifestyle. This is not something that’s done quickly and it’s not something that happens overnight, but it is required for sustained weight loss. To lose weight is not necessarily difficult in many cases, as the plethora of diet programs have shown. But to go right back to eating fast food frequently or choosing calorie-filled foods frequently means that it’s going to be impossible to keep the weight off. Instead, if you’d like to lose weight and keep it off for good, you have to be willing to change your lifestyle and commit to a healthier overall lifestyle.

    A Change in Lifestyle Doesn’t Have to be Hard

    A change in lifestyle isn’t something that’s instant and it does take work, but it doesn’t have to be hard. Small changes can make a huge difference. Following the right guidelines, learning what healthy eating looks like, and learning how to start eating healthy and make it sustainable are the main components for lifestyle changes that can lead to sustained weight loss.

    If you’re willing to follow along with the guidelines and learn how to make healthier food choices, it is possible to change your lifestyle and keep the weight off. This doesn’t mean avoiding fast food and other options all of the time, either. As you learn how to eat healthily and actually change your lifestyle, you can have treats without reverting back to the way you used to eat. Since it’s a lifestyle change, it’s something that sticks with you even if you decide to have a treat once in a while.

    What Needs to Change

    Basically, what needs to change is your relationship with food. It doesn’t really matter what your diet looks like right now. If it’s not a healthy diet, it needs to change. This is done by learning how to choose healthier options, learning how to eat the right amounts and stay feeling full longer, and, for some people, learning what other options they have besides a snack when they’re bored or if they feel just a little bit hungry. This can seem like a lot to change, but with the right help, it is possible to make these changes and start a new, healthier lifestyle that will not only lead to weight loss but make it easier to keep the weight off for good.

    Keep the Weight Off

    Weight loss shouldn’t just be about getting rid of the excess weight. It should also be keeping it off, which is the difference Suddenly Slim makes. You’ll learn how to live a healthier lifestyle, which means you won’t have to worry about the weight just suddenly coming back again. You’ll be able to make long-term changes that allow you to keep the weight off for good.

    Losing weight has always been a struggle for many people, but it doesn’t have to be. Making the right choices regarding food is something that can be learned and can enable someone to not only lose weight but keep it off for good. If you’re looking for a sustainable weight loss program, learn more about Suddenly Slim and the benefits it offers today.

    review comment posted icon  I was cleaning my closet and came across the little 10-day guide for Suddenly Slim, a program that I did years ago. I decided to give it a try again. I remember that the shakes were great and the program is based on clean eating, something I could use right now after months of pandemic binge eating. I hope to get the same result as in the past. After all, a 30-day initial investment is worth it, especially since most of us are at home anyway!

  • Questions & Answers

    Suddenly Slim Questions & Answers

    • What would you recommend for losing 50 pounds?

      To lose 50 pounds I would say first and foremost one needs to have the right mindset & awareness that there is NO SUCH THING AS MAGIC / A QUICK FIX / OR GIMMICK!

      Second I would suggest it takes MAKING A DECISION & UNDERSTANDING that health/wellness and weight loss is about A LIFESTYLE. I TOTALLY understand that nobody lives in a perfect world & there WILL BE TIMES where we will have/eat pizza, cookies, ice cream, etc etc etc BUT that can NOT be a routine for anyone!

      So we have The Proper Mindset, and the decision along with the understanding (as mentioned above) - so what’s next?

      We recommend The Suddenly Slim Program by FirstFitness Nutrition!!! This program is NOT Magic & this company/Program is NOT a start up deal that is here today & gone tomorrow! For OVER 30 Years - FFN has been impacting people’s lives with a solution (WHEN FOLLOWED CORRECTLY) to one wanting to lose weight - (not needing to lose weight). I say it this way because a lot of people who “NEED” it the most aren’t willing to do what it takes - so I say “WANT” too - again I’m not talking about a GIMMICK here!

      So the understanding is - It’s NOT magic, and a commitment (a decision) has to be made to be in it for The Long Haul (healthier lifestyle)!

      Suddenly Slim Transformation

      The Suddenly Slim (TRANSFORMATION KIT) thru FirstFitness Nutrition FIRST OF ALL comes with a Nutritional Eating Guide that consist of lean meats & proteins, UNLIMITED amounts of leafy green vegetables & salads (again I say UNLIMITED, anytime/any amount / all day / everyday), fruit, and low carb (not no carb - but low) breads/grains/etc. And we have a HEAVY emphasis on drinking 1/2 ur bodyweight in oz of water per day (for if there ever was A MIRACLE NUTRIENT - it would be water)!

      4 All Natural Products

      We next offer 4 key ALL NATURAL products that work TOGETHER but they are just The Cheerleaders - u still have to play the game (and the game is a lifestyle of Nutrition)!

      Product # 1 - Renue’

      - it’s our flagship product - an ALL natural colon cleanse & body detox for we believe A MAJOR KEY to health/wellness/and weight loss is gut health & proper elimination.

      Product # 2 - Xanolean

      - again ALL natural product that reduces hunger & cravings, gives energy (does have caffeine) mood enhancement & burns belly fat!

      Product # 3 - Body Fx Meal Replacement Shake

      - Great tasting / low calorie / fills u up / balances blood sugar (which is important) NOT protein shake (BUT MEAL REPLACEMENT Shake that contains carbs/protein/fats - the good carbs & good fats of course). This product is mostly used for breakfast b/c MOST people either # 1 don’t eat breakfast or they eat a unhealthy breakfast).

      Product # 4 - Trimbolic

      - it’s ALL Natural - high in fiber - fat & cellulite fighter that is used as a snack to fill u up so one is not picking & grabbing at foods that do not aid in health & weight loss.

      Again - drinking WATER (1/2 one's bodyweight in oz per day)!!!

    • How do I know what the right Reneú dosage is for me and what does a healthy outcome look like?

      What's most important is listening to your body.

      Everyone reacts to things differently, including supplements. One person may drink a pot of coffee to start off their day and another may have to rush to the toilet midway into a single cup.

      We recommend starting off with one-pill a day for the first 2 to 3 days to introduce it to your system. This will also help expose potential risks or allergies that are rare but not impossible. Once it has been introduced to the body, take 2 daily doses: one in the morning and one at night. The dosage may need to increase or decrease depending on your habits and body-type.

      Get started and react accordingly to what your system does.

      Is this going to keep me in the bathroom all day long?

      No, it will not keep you in the bathroom for elongated periods of time.

      If for any reason you are spending 8 hours of your 9-hour work day in the restroom, please seek medical attention.

      What you want to look for is 2 to 3 healthy bowel movements a day. By healthy bowel movement, we mean loose soft stool.

      Despite common misconceptions, diarrhea is a form of constipation. When looked at objectively, liquids may be passing but nothing substantial has.

      If you find yourself going too frequently, decrease your dosage to one-pill a day.

      If the issue persists, try taking one pill every other day.

      If constipation or bloating persist, you may need to take 2 pills in the mornings and 2 pills in the evening. Some people prefer taking a full dose once a day instead of dividing it into two separate daily doses.

      There have been successful and safe cases of people needing to take 6 to 8 total pills in their day.

      More is not always better! More is just more.

      Does my age effect my dosage? Will I need to increase my dosage over time?

      Age does not specifically alter dosages any more than its relevance to your body-type. Your daily habits also contribute. Exercise schedule and diet may sound like the most obvious factors, but Reneu promotes and works alongside your existing system. It is not designed to alter your life.

      As you age, your system will mature with your routine. Once your body is processing appropriately, the dosage should remain consistent.

      Bottom Line: It's going to make you go to the bathroom.

    • How do I keep the weight off?

      Losing fat and weight requires the right mindset and awareness. There is NO SUCH THING AS MAGIC PILL / A QUICK FIX / OR A GIMMICK! If that is what you are looking for… Suddenly Slim is probably NOT the right choice for you.

      Weight Loss, and maintaining your optimal body composition thereafter, is about A LIFESTYLE. We must make an informed decision and move forward recognizing that while it may not be easy, it will be worth it! While popular/fad diets may help you lose some weight initially, it usually comes back once the diet ends. They’re not sustainable. Those who need to lose weight, especially if they need to lose a significant amount, struggle to keep the weight off after the diet ends, because they often go back to their former eating habits, which usually causes the lost weight to return.

Shipping & Handling

A safe and accurate address for delivery must be provided at the time the order is placed. Once an order has shipped, is NOT responsible for lost or stolen packages CONFIRMED BY THE CARRIER to be delivered to the address provided for the order.

Since COVID-19, and the ensuing economic challenges in the USA economy, we respectfully ask that you allow some additional time for delivery for the carriers (USPS, UPS, and FedEx). Most orders still arrive on time, or near on time, but some may run late. We make every effort to get your order packed and into the carriers hands the same day, or by the next business morning if your order came in later in the previous day after carrier pickup, but we have no control over any delays that may happen within the shipping carrier's delivery system. Please order earlier for the time being if you are time-sensitive.

Orders that contain only FirstFitness Nutrition products have a shipping fee automatically calculated based upon the actual shipping weight of the items purchased. The charge ranges from $4.95 to $14.95.

For orders with NuMedica products you may choose from the shipping options below on the Order Checkout form in the Shipping Information section on the first line that says Choose Shipping Method.

Shipping Options

Country Option Schedule Cost
United States Standard 3-6 Days $4.95
United States Priority 2-4 Days $9.95
United States Free 7-10 Days $0.00
International FedEx International 4-7 Days $79.95*
International GlobalPost International 12-21 Days $39.95*
*International shipping costs may be higher depending upon package weight and destination. We will contact you for your approval of the additional amount if this occurs. may use the email or phone number provided on your Order to call or text you regarding Order Status or to inform you of changes to the Order Policy.

When your order ships we will send you a confirmation email with the delivery tracking information.

International Shipping

Shipping anything these days internationally is expensive. COVID resulted in more rigorous customs import processes, and now with much higher energy prices, international shipping rates are higher.

FedEx is the most reliable and faster carrier, at least for now, but they are expensive. Our FedEx international shipping fee is a minimum of $79.95. It usually makes more sense to get several months of supply (3 months or more) in one order to minimize the shipping expense per order over time. While the added weight of additional items may increase the base shipping price by a little (usually 10-25% depending upon total weight and destination), it is usually not by very much relative to shipping an additional small order later.

We also offer a lower-cost international shipping option using GlobalPost International for $39.95. So far, they have been reliable in getting packages correctly delivered but it takes 2 - 4 times as long to get the package delivered. Packages may take longer to process in the receiving country's customs process and status updates may not be reported as quickly. Please be patient if you choose this option to save money.

Some International orders may cost more to ship depending upon weight and location. If that happens we will contact you first and get your approval for any additional charge before proceeding. International orders may also be subject to additional customs fees and duties/taxes based upon the destination country's customs import laws and policies. These fees are NOT known or included on our order form and are typically charged and collected by the shipping carrier when they are delivering the product to it's final destination once the package has cleared the destination country's customs process. It is recommended that the buyer research custom import fees for the products/services they are importing beforehand to be aware of potential, additional fees.

Shipping Refrigerated Products

Our manufacturers formulate their probiotics to ensure their products retain viability until they reach the consumer. Probiotics that are recommended to be refrigerated remain so until the time of shipment, then shipped alongside an ice pack to ensure potency (Note: Ice pack will not arrive frozen, and product may not arrive cold). Orders placed on a Thursday-Sunday requiring cold shipping will not ship until the following Monday.


If your order has not been shipped yet, you can request a cancellation. Your original purchase amount will be refunded within three business days. If your order has already shipped, see Returns and Refunds.

Changes, Returns and Refunds

If you want to make a change to your order, please email us as soon as possible so we can make the change before your order ships. If your order has already shipped you may incur additional shipping charges for the second shipment and the return label for any products returned.

If we have made a mistake on your order, or the product arrives in a damaged or unusable condition, we will make every reasonable effort to right the situation quickly to your satisfaction. Problems of this nature must be reported to us within 5 business days of the package delivery date documented by the carrier status.

We accept returns subject to when the return is requested and the condition the product is returned in. All returns must first be authorized by contacting us. In your request, please let us know why you are returning the item(s). We will respond promptly with authorization, the return address, and a return shipping label if appropriate.

If your order has already shipped you can return any un-opened products within 30 days of receiving your order for a 100% refund of the price paid for the product, less the actual shipping charges we incurred to get the product to you originally and then returned, less a $10 restocking fee. Un-opened means the protective seal on the bottle or container, or the shrink-wrap on the box or kit, has not been broken and the product has not otherwise been damaged in any way. You may use the original packaging for the return or acquire your own. We will provide the return shipping label. We DO NOT accept returns for NuMedica products once the protective product seal has been broken.

Upon receipt of returned product(s), we will refund your credit card within three business days for the product(s) returned.
