Intermittent fasting has emerged as a popular diet trend promoted for rapid weight loss. This eating pattern cycles between periods of fasting and eating. Rather than controlling which foods you consume, intermittent fasting focuses on when you eat them. It’s essentially an eating pattern rather than a traditional diet.
One of the most challenging aspects of intermittent fasting is managing cravings during fasting periods. This makes perfect sense—when your body is deprived of nutrients, it produces hunger hormones signaling you to eat.
Fast Bars are nutrition snack bars designed to suppress appetite and make intermittent fasting periods more manageable. These bars contain a healthy blend of fats and nutrients that maintain your metabolism during fasting. Fast Bars also help curb appetite until your next meal or can serve as a meal replacement on diets like keto. If you’re following a keto diet, ensure you stay in ketosis with the Lumen Metabolism Device.
While substantial evidence shows intermittent fasting is effective for short-term weight loss, the long-term health effects remain unclear. However, we can thoroughly examine Fast Bars and address key questions about their pros, cons, purchasing options, and overall value.
Overview: Fast Bars
Fast Bars are crafted from a premium selection of nuts designed to suppress appetite during fasting. Nuts are ideally suited for this purpose because they contain high levels of beneficial fats and protein while maintaining extremely low carbohydrate content. This composition also makes them popular among keto dieters. These bars function as either meal replacements or daily snacks. The creators recommend consuming at least one bar daily around breakfast time or as a meal substitute.
Remember that Fast Bars are specifically designed to support intermittent fasting diets. While you can certainly enjoy them as regular snacks, the creators claim maximum effectiveness when integrated into an intermittent fasting routine. Also note that this is a nutrition bar, not a protein bar. For those seeking an excellent protein bar, check out our Built Bar review to discover why it’s our current favorite.
Each Fast Bar contains 21g of unsaturated fats, 5 grams of protein, and 14 carbs—representing only about 5% of the daily value. Each bar also provides substantial amounts of fiber, calcium, and iron. All products contain tree nuts, making them unsuitable for those with severe nut allergies. The products are vegan and soy-free, though manufactured in a facility that processes soy, wheat, and egg products. That’s not critically important but worth noting.
Advantages

- Somewhat expensive
Who Makes Fast Bars?
Fast Bars are manufactured by L-Nutra, a nutrition technology company specializing in supplements that support intermittent fasting. Founded in 2009 by Dr. Valter Longo, L-Nutra was inspired by the goal of creating products that improve human health and longevity. L-Nutra pioneers technologies that mimic and enhance fasting effects to “unleash the body’s natural ability to fuel and rejuvenate itself and promote longevity.”
L-Nutra’s advisory board comprises several MDs and Ph.D. holders, lending credibility to their products. They claim their Fast Bar products represent the culmination of over 25 years of scientific research on fasting.
L-Nutra also produces ProLon, a fasting-mimicking diet program designed to enhance performance, facilitate weight loss, promote cellular renewal, and improve metabolic health. ProLon is based on the same fasting research that informed Fast Bar development.
How Do Fast Bars Work?
Fast Bars function by providing the body with a modest supply of fats and proteins to maintain metabolic activity during fasting. The primary ingredient in each bar is nuts, which offer excellent quantities of healthy fats and protein while maintaining low carbohydrate content. Fast Bars can be used during intermittent fasting or serve as meal replacements or hunger-suppressing snacks.
When the body lacks food, it automatically slows metabolism to conserve energy—counterproductive for weight loss. Fast Bars provide your body with essential nutrients that keep your metabolism active and force your body to burn stored fats for weight loss. Fast Bars also suppress appetite, making it easier to maintain your fasting schedule.
Ingredients in Fast Bars
Virtually all Fast Bar ingredients are nuts, including macadamia nuts, pecans, and almonds. Most bars also contain honey as a natural, low-sugar sweetener.
Nuts are excellent diet foods due to their extremely low carbohydrate levels and high protein and fat content. These nutrients are crucial when fasting or following low-carb diets. Nuts are also highly satiating, which reduces appetite and minimizes cravings.
Safety and Side Effects
All ingredients in Fast Bars are natural and do not produce negative side effects. Since they contain tree nuts, those with tree nut allergies should avoid them.
Where to Buy and Cost
You can purchase Fast Bars directly from the company website. They don’t appear to be available on Amazon or in physical retail stores currently.
Fast Bars: Are They Worth it?
Absolutely. Fast Bars feature excellent ingredients that are completely natural and recognized as healthy. While we remain cautious about fasting’s health effects, Fast Bars certainly make a nutritious snack option and a superior replacement for chips or cookies.
