The 60-hour Keto Reboot promises to help you reach ketosis through structured fasting. Our research team was impressed by how much information about ketosis Pruvit provides on its website, though we were disappointed that most of it didn’t actually explain how or why Keto Reboot itself works.
Undeterred, our researchers dug into the ingredients that make up the Keto Reboot system and scoured the web for reviews from verified users.
What Is Keto Reboot?
Keto Reboot is a 60-hour fast built around a four-product system — ketones, broth, and energy drinks designed to make the fasting window more manageable. Oral ketones like the BHB used here have been shown to raise blood ketone levels, according to Nutrition & Metabolism, though that’s a different question from whether they actually drive weight loss. Fermented leucine, common in muscle-building supplements, showed some benefit for visceral fat loss in an older study published in Sports Medicine, though a more recent study in Nutrients found leucine had no effect on muscle or fat.
How Did Keto Reboot Start?
Pruvit, the company behind Keto Reboot, is a multi-level marketing company built around the idea of helping people “bio-hack” their bodies for better health, holding an “A+” rating with the BBB. The company’s stated mission centers on supporting a ketogenic lifestyle through its product line.

Keto Reboot Claims
The makers claim Keto Reboot will control cravings, maximize energy, protect muscle mass, and help hold users accountable for their results.
Keto Reboot Ingredients
The system bundles five products: Keto OS NAT, Better Broth, Signal OS, Keto OS Pro, and Mito Plex.
Keto//OS NAT (4 packets)
Marketed to maximize brain power and physical performance, this raspberry-lemonade-flavored drink includes the N8 Max NAT Blend (12.6g), KetoNAT (R-Beta Hydroxybutyrate), L-Taurine, Fermented L-Leucine, and C-Med 100 (inner bark of Uncaria tomentosa).
Beta-Hydroxybutyrate
A ketone body commonly used in ketogenic supplements to raise BHB levels in the bloodstream, according to Nutrition & Metabolism, with manufacturers claiming this helps push the body into ketosis faster.
L-Taurine
A common energy-drink ingredient found abundantly in the brain and muscle tissue, per Molecular Vision — though its full physiological role remains somewhat unclear.
AC-11
An extract commonly used in dietary supplements and skincare products, according to the Dermatology Online Journal.
Better//Broth (4 packets)
The only “food” you’ll consume during the 60-hour fast — a chicken and beef bone broth in thyme and salted caramel flavors, containing beta-hydroxybutyrate, fermented L-leucine, and type II collagen peptides.
Type II Collagen
Research in PLoS One links this collagen type to reduced inflammation in the body.
L-HICA
A leucine metabolite used as a muscle-building supplement, included here to help prevent muscle breakdown during the fast.
Rooibos Tea
A caffeine-free South African tea, often taken with milk and lemon.
5-HTP
A natural compound sometimes used for depression, with early research suggesting a possible appetite-suppressant effect, though more study is needed.
Signal//OS AM/PM (6 packets)
Marketed to help repair DNA, improve concentration, and support immune function, containing vitamin B12, Eleutherococcus senticosus extract, valerian root, reishi mushroom, BioPerine, and ashwagandha.
Eleutherococcus Senticosus Extract
An adaptogenic herb linked to improved workout capacity, reduced stress, immune support, and — per Nutrients — improved memory.
Reishi Mushroom
Common in Eastern medicine, native to Asia.
BioPerine
A black pepper derivative that helps the body absorb other nutrients more effectively.
Keto//OS Pro (1 packet)
Includes an N8 Bioavailability Blend of whey protein isolate, MCT powder, KetoNAT, fermented L-leucine, and C-Med 100.
MITO//PLEX (3 packets)
Includes a Mitochondrial Matrix Support Blend of creatine monohydrate, Mito2PQ, and C-Med 100.
Does Keto Reboot Work?
Will you lose weight during a Keto Reboot? Yes — any 60-hour fast produces weight loss. The bigger question is whether it lasts, and that depends on sticking to a strict ketogenic diet after the fast ends.
Keto Reboot Benefits and Results
Feedback on Amazon and Facebook has been mixed, with some customers calling it one of the toughest 60 hours they’ve experienced. There are no testimonials on Pruvit’s official site, though as of our research, 634 Amazon reviewers rated the program 4.2 out of 5 stars.
Keto Reboot and Weight Loss
Research in the International Journal of Obesity found intermittent fasting can support weight loss, but typical intermittent fasting windows fall well short of 60 hours, which raises real safety questions at that length. Cureus notes more research is still needed to determine whether extended fasting leads to lasting weight loss or contributes to weight regain down the line.
How to Take Keto Reboot
The program follows a set schedule: eat normally on Sunday and take Signal//OS PM 30 minutes before bed; on Monday and Tuesday, take Keto//OS NAT, Signal//OS AM, and MITO//PLEX upon waking, Better//Broth at noon, Keto//OS NAT again at 3pm, Better//Broth at 6pm, and Signal//OS PM before bed; on Wednesday, take Signal//OS AM, MITO//PLEX, and Keto//OS Pro upon waking. Throughout the 60-hour fasting window, only water is allowed — at least a gallon a day, since the formula’s salt content makes dehydration a real risk if intake is too low.
How Much Does Keto Reboot Cost?
The kit runs $110 on Amazon or $79 through the official Pruvit website, covering everything needed for one full 60-hour fast.
Potential Keto Reboot Side Effects
Stomach-related issues — pain, cramping, and diarrhea — are the most commonly reported side effects. Broader fasting-related side effects can include headache, dizziness, fatigue, muscle loss, food cravings, irritability, and mood swings.
Keto Reboot Pros and Cons
Pros: An informative official website and free post-fast recipes.
Cons: High cost, real safety concerns with 60-hour fasting, a strict post-fast diet requirement, complaints about taste and customer service, no money-back guarantee, and the fact that ketosis is achievable without this specific product at all.
The Bottom Line on Keto Reboot
Is a nearly three-day fast, subsisting mostly on bone broth and supplements of uncertain benefit, really the right approach? Weight loss is a genuine journey, but it doesn’t have to be this difficult. A steady, sustainable combination of diet, exercise, and long-term consistency will generally get you further — and more safely — than an extended fast built around a proprietary supplement system.
