Lean Protein Bars with Prebiotic Fiber for Weight Loss, Fat Burning and Immune Health
When it comes to losing weight and burning fat, LynFit Lean Bars are the best protein bar you can buy! No other protein bar specifically promotes weight loss, helps to promote fat burning by boosting the metabolism, and improves digestive and immune health without slowing your weight loss, the way our protein bars do.
The unique formula in Lean Bars is powered by our proprietary combination of prebiotic fiber and protein powder that work together synergistically to reduce and rebalance blood sugar levels safely, boosting metabolism, and creating a fat-burning environment within your body naturally.
We developed LynFit Lean Bars based on the belief that you shouldn’t have to sacrifice taste, even when transforming your health. and that they should make it easier, and more cost-effective. Along with our medical advisory team, we spent over a year working with leading flavor and sensory experts to perfect the taste of our Lean Bars. The natural sweetness in our formula comes from a proprietary premium grade, non-gmo sweet whey, super low to no-calorie sugar alternatives that are absorbed by the body, but not metabolized, so it won’t spike blood sugar levels that slow weight loss and stop the fat-burning process.
Everything we do, every product we make, is specifically designed to make losing weight faster, easier, and prevent metabolic slowdown and weight regain, starting with controlling blood sugar levels. Nutritious and delicious!
LynFit Lean Bars are high-protein, high-fiber, low-carb, and low-calorie whole food protein bars made with real ingredients like pure metabolic boosting whey protein and prebiotic fiber flavored with pure, clean ingredients like defatted cocoa, powdered peanuts, Tahitian vanilla, and ground almonds.
We know how hard losing weight is, so we go the extra mile to deliver delicious protein bars that nourish your body and fuel your weight loss, that are also good for you. You’ll begin to crave these protein bars, and thankfully, the more Lean Bars you eat, the more weight you’ll lose. Lean Bars taste so good that the old standby favorites that cause weight gain won’t stand a chance. Say goodbye to cravings and hello to your waistline!
The biggest problem we face when trying to lose weight is finding adequate time to eat enough high-quality protein and nutritious meals in the midst of busy days and over-stressed lifestyles. Lean Bars were created for this very reason. Fast, easy, and so delicious—you’ll stop craving the snacks that cause weight gain, and you’ll start craving foods that are good for you. Not sticking to our diets is the #1 reason most weight loss plans fail and Lean Bars solve this problem.

WHAT MAKES LEAN BARS DIFFERENT?
Not all protein bars are created equal or for weight loss. LynFit Lean Bars are naturally delicious and what really makes them unique is that they are the only protein bar that’s specifically formulated for weight loss and boosting sluggish metabolisms. At LynFit, we specialize in how your metabolism works and know how important the ingredients we use are.
That’s why Lean Bars are made with the same premium, all-natural, metabolic boosting, pure, whey protein powder that you’ll find in our awesome tasting, wholesome Complete Protein Powder. They are free of processed carbohydrates, sugars, wheat, gluten, soy, and trans fats. Plus, they contain 10 grams of filling prebiotic fiber to crush cravings, keep you feeling fuller longer, balance blood sugar spikes, and satisfy your hunger for the not-so-healthy sweets we all love. Lean Bars contain more prebiotic cultures and health benefits than yogurt, with less sugar, and better-tasting too, so every time you eat a Lean Bar you’re also improving your digestive and immune health.
Lean Bars are the only bar that kills cravings versus causing them, thanks to their protein and fiber ratio, and because of what they don’t contain: trans fats, sugars, and excess carbs that even vegan bars can contain.
- No added sugar
- 99% dairy-free
- No soy
- No gluten
- No junk or carbs
Lean Bars are practically cholesterol-free, unlike most Paleo and Keto protein bars. The protein we use has the highest PER (Protein Efficiency Ratio), so it’s easily absorbed by the body and boosts metabolism instead of slowing weight loss. Other less complete, inferior proteins are not as easily used by the body, so most of it is unused or worse, due to the higher fat content of most bars, and it’s stored as dangerous belly fat.
At LynFit, that is never an option. You’ll see and feel the difference the same day you start eating them. The scale doesn’t lie!
They are known to satisfy hunger and cravings for up to six hours. Take stress eating to a whole new metabolic boosting level by grabbing a Lean Bars when you’re stressed, and take comfort in the fact that what you’re eating will promote weight loss, not prevent it!
Inspired by nature and perfected by LynFit, Lean Bars are clinically proven to help control blood sugar levels thanks to its unique combination of protein and prebiotic fiber that’s been known to improve weight loss, immunity, and digestion.

What's In Them?
The Power of Protein! Did you know that Lean Bars have more protein than two eggs, yogurt, and most pre-packaged meal replacement shakes like Boost® and Ensure®? Add to that, a higher quality protein source compared to vegetarian sources. Even if you’re not trying to lose weight, protein is the best way to power your health and your life.
Ninety percent of women over 40 are deficient in protein, which slows metabolism, makes your body resist weight loss, and is a big cause of weight gain and sagging, crepey skin. Your body relies heavily on getting enough of the right kind of protein. It’s the major component of connective tissue, skin, and bones. As we age, our protein needs increase, and we tend to eat even less of it.
Your body cannot digest the types of proteins we feed it, and that’s why supplementing your diet with Lean Bars and Protein Shakes is critical to ward of preventable diseases like osteoporosis and help tighten and tone loose, sagging, crepey skin. That’s why making sure you get enough high-quality protein in your diet is critical.
At LynFit we say, “A shake or Lean Bar a day keeps the doctor and crepey skin away. It’s better than the old-fashioned apple!”
There is evidence that consuming adequate amounts of protein may help reduce joint pain and promote healing in athletes or anyone who is active, while improving the quality of your sleep when eaten before bed, healing your gut, and restoring digestive balance—but only if you’re eating a LynFit Lean Bar!
Protein helps balance and restore meat intake. Animal foods such as muscle meats, pork, and excessive chicken-eating get a bad rap for good reason. Most of us tend to overeat them, and our bodies cannot digest them as easily as we age. They are also overloaded with saturated fats that slow weight loss, prevent fat burning, and clog our arteries. They speed up the aging process and decrease our lifespan. This also includes the new trending collagen that comes from sources you don’t want to know about.
But the high-quality, pure, metabolic boosting whey that’s used in our bars is packed with the amino acids your body needs, in exactly the amount needed (too much and you slow weight loss), to help counteract these issues. You can enjoy delicious comfort food knowing you’re feeding your body what it needs while enjoying all the benefits of a protein-rich diet without any of the drawbacks.
Lean Bars are an excellent source of prebiotic fiber. They are the only protein bar that uses the best source available (high-quality whey) combined with isomaltose prebiotic fiber from chicory. This highly specialized form of prebiotic fiber feeds trillions of foreign cells (good bacteria) that are absorbed in the digestive tract for better absorption (this also helps avoid the gastric distress that other prebiotics can cause). It’s good food for gut flora. Medical science and doctors are now suggesting that we feed gut flora for optimal health for our digestive system, cognitive, emotional, psychological, immune, and metabolic health.
Some other protein bars may add prebiotics, but LynFit is the only protein bar that uses the best source available that is highly stable through processing, increasing and improving shelf life, making it better able to stand up to stomach acids. It is backed by 17 published studies and FDA GRAS status.

How To Use Them
How much to take and when: Consistency and frequency matter! Suggested Usage: Enjoy 1–2 Lean Bars per day as a snack or meal replacement or anytime your cravings are about to get you into trouble.
SPECIAL INSTRUCTIONS: LynFit Lean Bars are made in small batches to ensure quality and the date you see marked on the label is a “Best By” date, not an expiration date. Sometimes Lean Bars can become hard (due to the lack of preservatives and their low fat make-up) or lose shape (caused by heat or being smooshed) during shipping. That’s why we suggest storing them in the refrigerator or freezer, and if needed remold them back into shape, if it makes you feel better. Make sure to soften by allowing them to reach room temperature. You can also remove it from the wrapper and heat it for 5 seconds (more or less) or dunk it in your tea before you bite into it.
FAQs
Yes! LynFit Lean Bars and Protein shakes are an ideal complement to each other. Both are perfect for curbing snack cravings on-the-go. With 5-10 grams of prebiotic fiber and 19-24 grams of high-quality protein in each, you can power through your workout, make it through your busy day, and keep your gut happy and healthy while continuing to lose weight and melt off belly fat.
We recommend that you start with either one Lean Bar or Complete Protein Shake at-a-time versus both in the same meal to see how much your metabolism can handle. You can ramp up or add more each day or add as snacks according to your specific metabolic needs. Some need more, others less to reach their goals. Tracking your weight daily is a good way to measure that.
When you feel ready, two or three Lean Bars or Protein Shakes in a day are totally fine.
Yes! One of the things that make our Lean Bars different is that they are designed to boost metabolism, making it easier to lose weight and burn fat. They have a unique nutritional profile that allows them to be used as meal replacements, yet low enough to also be enjoyed as healthy snacks that keep you feeling fuller longer (for up to 4-6 hours).
LynFit whey proteins are carefully micro-filtered whey, meaning that the whey has undergone a micro-filtering process to remove virtually all of the harmful bacteria, spores, and lactose. This process separates them out leaving the most valuable parts of whey protein intact. LynFit whey is re-filtered using a very fine filter called a sieve, a.k.a. Ultra Filter, to clean it up even further. During this highly specialized, ultra-filtration process, only substances with a low molecular weight pass through the membrane in the filter. That’s how the best quality whey is made, leaving only pure protein (amino acids) intact. This process also separates any inferior proteins that may have passed through from the pure, natural whey proteins. The result is the highest quality whey protein, rich in alpha-lactalbumin and beta-lactoglobulin (two special proteins found in whey that has immunological benefits), and low in fat. Undenatured whey proteins obtained in this manner also have a better solubility, which means it dissolves easily, even in water.
This is how LynFit Complete Proteins got their name, and your beloved, best-tasting whey protein is lactose-free. Unlike vegan sources, you don’t have to combine it with carbs that could negatively affect weight loss.
The final product is one you can enjoy that’s the very best quality, safe, easily mixable, and healthy for everyone in your family. Most importantly, it is the most delicious protein you’ll ever taste. Just ask Martha Stewart who was our taste tester!
