Backed by solid research from the University of Southern California, these bars promise to help you reach your weight management and intermittent fasting goals. But are these plant-based bars any good? Learn more here in our Fast Bar review.

What Is a Fast Bar

These bars do exactly as the name suggests: allow you to eat something while fasting but without actually breaking the physiological processes that a fast induces. That is, you can eat a bar to sate your hunger but still be fasting in the physiological sense— nifty huh?

How Does Fast Bar Work

Fast Bar and its dedicated intermittent-fasting bars are part of a broader movement called fasting-mimicking. In essence, you're tricking your body into thinking you are fully fasting so you can collect the health benefits, all while actually providing it with some sustenance along the way.

The fasting-mimicking diet is making waves in the heath and fitness and wellness worlds and is set to become the next big craze. Like the five-day ProLon plan,

Fast Bar by L-Nutra Inc. has its roots in solid science. In fact, the team behind the innovative bars relied upon nutri-technology and fasting research that was 20 years in the making.

A disclaimer: Fast Bars are not designed or intended to diagnose, treat, cure, or prevent health issues. Instead, they are a bar that provides nourishment to your body and may help you on a fasting-mimicking diet.

In turn, they may help with weight management as they support your body's natural fasting mode processes. Would-be bar-fast enthusiasts with pre-existing conditions should speak to their health care providers before embarking on any fasting plan.

What Is In Fast Bars?

Fast Bars contain a proprietary blend of plant-based macro and micronutrients. Ingredients such as macadamia nuts, pecans, and cocoa nuts go into each nutrition bar. These premium nuts offer up beneficial fats to curb food cravings and keep you on track until your next meal post-fast. In addition, Fast Bar's products are:

  • Gluten-free
  • Non-GMO
  • Soy-free
  • Dairy-free
  • Keto-friendly

Much like a protein bar, Fast Bars contain a decent amount of the good stuff with five grams of vegan-friendly protein and six grams of carbohydrate. It's also worth mentioning that each of Fast Bar's bar products contains zero grams of trans fat.

How to Buy Fast Bar Products

The easiest way to buy Fast Bar products is on the company's own website, where you'll also find a wealth of information in the form of videos, blogs, and articles. You have a choice of either buying your Fast Bars in a box of 15 or 30. There are four options to choose from:

  • Nuts and cacao chips
  • Nuts and dark cocoa
  • Nuts and honey
  • Variety (a mix of the three flavors)

Alternatively, you can subscribe for a regular delivery and save 10%.

Once you've made your choice and it's in your shopping cart, simply enter your email, complete your payment and the company will take care of the rest. We like that shipping is free for any order over $50 dollars.

What Can I Snack on During Intermittent Fasting (IF)?

IF is a great way to support a healthy lifestyle. Research suggests that we don't need to eat as often as we do, and many fasting proponents believe that our bodies are designed to go lengthier periods without food.

When we fast, our bodies have time to repair cells and carry out general maintenance.

Not eating for extended periods can prompt the body to kickstart processes that are put on pause when we're consuming food and drinks frequently throughout the day.

Some people like to fast for two or three days at a time, or even longer. But most IF fans choose to limit their food intake for a period of 12 to 18 hours. 

When you think about it, it's quite easy to do. Instead of eating breakfast, for example, wait until midday before having a meal, then stop eating after 8 pm, or whatever works best for your schedule. The 16:8 IF plan — no food for 16 hours and an 8-hour feeding window — is an easy way to start if you're new to IF.

Of course, the whole idea behind fasting is that you do not snack unless it's inside the feeding window you've set for yourself. But with a dedicated Fast Bar snack, you can quickly and easily top up your body with energy to keep going without dramatically interrupting the body's fast mode.

It certainly sounds too good to be true, but L-Nutra, the manufacturer of the Bars and creator of the ProLon fasting-mimicking diet, relied upon 20 years of nutritional research and testing to create its products.

FAQS

Does the Fast Bar break your fast?

No, not technically. Fast Bar is the first bar designed for intermittent fasting so that you can extend your fast window without breaking the fast. The bar is specifically formulated to not induce high blood glucose.

How do Fast Bars work?

Fast Bars have a specific formula of macro and micronutrients that allows your body to feel like you’re still fasting. When there’s no other food in your system, eating a Fast Bar will not trigger food-sensing pathways. Essentially, you’re fasting with food.

When should I eat Fast Bar ProLon?

It’s best to eat a Fast Bar if you follow a keto or paleo diet, practice intermittent fasting, or skip breakfast. You can eat one in the morning while fasting, as a snack any time of day, or even as a late night treat.

What's in a Fast Bar?

The ingredients of a Fast Bar include macadamia nuts, honey, pecans, almonds, almond butter, coconut, inulin, flaxseed, coconut oil, coconut flour, sea salt, natural flavor, mixed tocopherols (preservative), citric acid, and ascorbic acid.

What is a fasting bar?

Fast Bar is a blend of ingredients including premium seats and nuts using the science of ProLon. With a fasting bar, you get the calories and nutrients you need to nourish your body while fasting.

Are Fast Bars gluten free?

Yes, Fast Bars are vegan and gluten-free. They come in three flavors: Cocoa Nuts, Nuts & Honey, and Nuts & Nibs. The ingredients include a blend of almonds, pecans, and macadamia nuts to fuel your body throughout the day.

Fast Bar Costs

Depending on the flavor you choose, you can order packs of 5, 10, 12, 20, or 30 bars at around $3 per bar. If you sign up for a monthly delivery, you receive a 10% discount. Shipping is free for all orders over $50.
