About ProLon’s Intermittent Fasting Bar–Fast Bar

What’s inside the box

Fast Bar comes loaded with a bounty of premium ingredients, catering to the discerning palate while meeting strict dietary standards. Here’s what each bar contains:

Premium nuts: A fusion of almonds, pecans, and macadamias, all non-GMO, offers a mix of monounsaturated and polyunsaturated fats, vital for heart health and brain function.

Sustainable energy: With 190 calories per bar, including 14g of total fats, it provides sustained energy without spiking blood sugar levels, thanks to its low glycemic index.

Fiber and protein: 8g of dietary fiber and 5g-6g of plant-based protein support digestive health and muscle maintenance, essential during fasting periods.

Minimal sugars: Only 3g of added sugars ensure that the bar maintains its fasting-friendly profile while adding just enough sweetness.

Essential micronutrients: Each bar is also a good source of iron and calcium, providing 6% and 4% of your daily value, respectively, supporting bone health and energy metabolism.

This combination of ingredients has been scientifically formulated to offer a fasting-friendly nutrient profile that supports your body’s energy needs while maintaining a state conducive to the benefits of fasting.

How to use

For effective use, consume one Fast Bar during your fasting period, preferably in the morning after waking or before your sleep at night. This timing helps manage hunger without interrupting the fasting state. 

The clinical study underscores that this strategic consumption aligns with maintaining blood glucose and ketone levels, supporting metabolic health during fasting. 

It’s recommended to enjoy one Fast Bar daily as part of a balanced diet to ensure nutritional adequacy while pursuing your fasting protocol.

How does Fast Bar compare with other intermittent fasting bars?

Fast Bar distinguishes itself in the fasting support market with its unique nutrient composition that allows consumption during fasting without breaking it—a claim substantiated by clinical research. 

Unlike its competitors, such as GoMacro’s intermittent fasting snacks and Fastful’s pre-fasting nutrition bars, Fast Bar is designed not to trigger the body’s nutrient sensors, thus maintaining the fasting state. 

While GoMacro focuses on organic, high-protein snacks and Fastful offers a balanced meal in a bar to prepare for fasting, Fast Bar is the only bar clinically tested to sustain ketone levels and manage glucose response, mimicking a water-only fast. 

This scientific backing and the specific fasting-friendly formulation set Fast Bar apart, offering a unique solution for those committed to intermittent fasting.
