More energy, stable blood sugar, no more cravings, and maximum fat burning – that’s just a glimpse of what so-called exogenous ketones promise: a drinkable powder that induces ketosis even while eating carbs.
Does this new super supplement deliver on its promises?
To be honest, I was very skeptical at first. The only reason I gave it a chance was because my trusted coaching colleague Sebastian recommended it.
Was I disappointed?
In this article, I’ll share my full experience with exogenous ketones – going far beyond my initial short-term review – including insights from others around me. Because reactions have been surprisingly diverse…
Effects and Applications
Recently, I saw a video from a doctor who was completely out of shape but offered “weight-loss coaching.” He said:
“Exogenous ketones are garbage. It’s like rubbing sweat on yourself because people sweat during workouts. But you didn’t even work out!”
No, YOU haven’t worked out in a while, buddy, I thought.
But is he right?
What Exogenous Ketones CANNOT Do
Many people confuse exogenous and endogenous ketosis.
Once they discover the difference, they assume exogenous ketosis doesn’t work.
Plot twist – even for Dr. D.D. with the sweat analogy: It works differently. It just requires some background knowledge and nuanced thinking – let’s dive in.
Endogenous Ketosis – The Natural Way Into Ketosis
Endogenous, natural ketosis isn’t fun. You need to give up carbs. For weeks.
Here’s what happens: the body uses gluconeogenesis (converting protein to carbs) and ketogenesis. It rapidly turns body fat into ketones.
These ketones fuel the brain and muscles, reduce stress and inflammation, suppress hunger, and melt fat. Awesome.
Takeaway: The main benefit of natural ketosis is that ketones are made from your body fat – and they help burn it fast.
The downsides: You have to give up carbs, and it’s not meant to be a permanent solution. Smart cycling is necessary to stay healthy.
Drinkable Ketones – The Fast Track to Ketosis
Exogenous ketones are a powder you simply drink. They enter your bloodstream and deliver the same effects as endogenous ketones. One-to-one. Provided you use the right type (rBHB ketones).
The key difference: you can still eat carbs.
R-BHB and Fat Loss – Can It Work?
Sure, ketones are calories. So shouldn’t they hinder fat loss?
That’s a fair question. But keto drinks do promote fat burning – just through a different mechanism.
When your body naturally enters ketosis, ketones are the end product of intense fat burning (via beta-oxidation).
That process is bypassed with exogenous ketones.
Step 1: You drink the keto shake – ketones appear in your blood. No fat was burned, no new metabolic pathway required.
Why It Works: Fat Metabolism Optimization
- They reduce inflammation – just like natural ketones. This improves insulin sensitivity. Less fat gain (especially belly fat), more muscle, faster metabolism – a positive feedback loop.
- Ketones curb cravings. They prevent blood sugar crashes (Falkenheim et al. 2022), regulate hunger hormones (Stubbs et al. 2018), and reduce sugar cravings.
- Better sleep & less stress. They enhance deep and REM sleep phases (Robberechts et al. 2023). That means better recovery, more fat burning, less stress, even if you sleep less.
“Well, then sleep faster!” – Arnold Schwarzenegger
Yes, it really works.
More energy, stable blood sugar, no more cravings, and maximum fat burning – these are just a few of the promises surrounding so-called exogenous ketones: a drinkable powder that induces ketosis, even while consuming carbohydrates.
But does this novel super-supplement live up to the hype?
To be honest, I was highly skeptical of the product at first. The only reason I gave it a try was because my trusted coaching colleague Sebastian recommended it.
Did it disappoint me?
In this article, I’ll share my personal long-term experience with exogenous ketones beyond my initial impressions – including some insights from people around me, whose responses were surprisingly diverse.
Effect and Areas of Application I recently watched a video from a doctor who was completely out of shape but offered “weight loss coaching.” He said:
“Exogenous ketones are trash. It’s like rubbing yourself with sweat because people sweat during workouts. But you didn’t even work out!”
My thoughts? “No, YOU’VE never worked out, buddy.”
But let’s break it down: was he right?
What Exogenous Ketones CANNOT Do Many people confuse exogenous with endogenous ketosis. They discover some differences and then assume exogenous ketosis doesn’t work.
Plot twist – also for Dr. D.D. with the sweat analogy, if you’re reading this: it works differently. But to understand that, you need some background knowledge and nuanced thinking – which I’ll explain right now.
The Truth About Ketones: Comparing Endogenous and Exogenous Ketosis Endogenous ketosis is the natural way into ketosis – and let’s face it, no one enjoys it. It requires giving up carbs. For weeks.
Here’s what happens: your body uses gluconeogenesis (converting protein to carbs) and ketosis. The latter produces ketones from your own body fat at high speed.
This comes with many benefits: ketones fuel your brain and muscles, reduce inflammation and stress, erase hunger, and melt away fat. Amazing.
Note: The main benefit of natural ketosis is that ketones come from your own body fat and rapidly burn it.
The downsides? You need to give up carbs, and it’s not suitable for long-term use unless you cycle it smartly.
Drinking Ketones – The Fast Track to Ketosis Exogenous ketones are powders you drink. They enter the bloodstream and create the same effects as endogenous ketones. One-to-one. As long as you use the right kind (r-BHB ketones). The main difference: you can still eat carbs.
r-BHB and Fat Loss – Can It Work?
At first glance, ketones are extra calories. Shouldn’t they hinder fat loss?
Fair point. But keto drinks do promote fat burning – just in a different way.
Normally, ketones are the end product of intense fat burning (via beta-oxidation). That’s skipped with exogenous ketones.
Step 1: you drink the keto shake. Ketones appear in your blood – without your body needing to burn fat or learn new pathways.
Why It Works: Fat Metabolism Optimization
The ketone powders affect your metabolism differently. Before we get to the real-life experience, here’s how they work:
- Reduce inflammation (like natural ketones)
- Improve insulin sensitivity
- Lead to less fat gain (especially belly fat from insulin resistance) and better muscle growth
- Increase overall metabolic rate and fat burning
Ketones Curb Cravings Cravings usually result from blood sugar crashes. Ketones help stabilize that (Falkenheim et al. 2022).
Result? No hunger, more energy, better mood. They also regulate hunger and appetite hormones (Stubbs et al. 2018). This reduces sugar cravings and boosts fat metabolism.
Better Sleep & Less Stress with r-BHB Ketones Drinking ketones tends to improve deep and REM sleep (Robberechts et al. 2023).
Why is that important? In REM sleep, we process emotions and reduce stress. In deep sleep, physical systems regenerate – including stress systems and fat-burning processes.
With ketones in your system, you spend more time in these stages. So even with less sleep, your sleep becomes more efficient.
“Then sleep faster!” – Arnold Schwarzenegger.
Yes, it really works.
We haven’t even covered all benefits yet, and it’s already clear: exogenous ketones work. Just differently.
Now let’s get to the experiences.
Are Exogenous Ketones Dangerous? Side effects.
Side Effects of Pruvit r-BHB Ketones Luckily, I didn’t experience side effects. But the most common one (though rare) is detox-style diarrhea if you chug the drink too fast without being used to it. Easy fix: drink slowly over 15 minutes.
Even rarer: mild headaches after the first 4-6 uses.
Some users also lose weight rapidly in the first weeks, possibly due to shedding water retained from inflammation (e.g., in legs).
How I Use Exogenous Ketones
There are countless ways to use them. I typically drink keto shakes in the morning to boost focus and stay protected from my biggest weakness: sweet snacks. That was a huge breakthrough and made fat loss much easier.
I also use them during workouts – especially when training fasted, when I need sharp focus or lightning-fast reflexes (which ketones noticeably enhance, especially when fatigue sets in).
And when I need to drop a few pounds (like after winter), I use them immediately.
My r-BHB Ketone Experience: What They Did for Me
I’ve been using exogenous ketones for over 3 years now. I’ve tested them in various contexts and the longer I use them, the more impressed I am.
Effects kicked in the very first time, within an hour. It was like someone turned on a light in my brain – clear, fast thinking. That clarity now persists even without ketones.
With ketones, I complete 6-8 hours of desk work in just 3. After tough days, I still have energy and motivation to train or go out.
They also eliminate cravings for up to 10 hours, improve my focus, enhance my gluten tolerance, clear up my skin, and improve my sleep.
I even lost noticeable body fat – despite already being lean (you can see it in the photo above). So yes, full-spectrum effects.
Results in Athletes
As a health coach, I help many clients improve fat loss and performance, including athletes.
Athletes use the drinks to improve training and recovery. Results vary: some report sharper focus and reflexes, others feel improved stamina or a “second lung.” Reactions differ widely.
Weight Loss with Exogenous Ketones: How Many Kilos?
Most of my clients, friends, and peers use r-BHB ketones to burn fat without hunger, boost post-work productivity, or improve sleep. Losing belly fat, waking refreshed, no afternoon crash, no caffeine dependence – it’s a new life for many.
Weight loss results can be spectacular, sometimes even in the first few days. Certainly within 2-4 weeks. Like Tina’s experience:
Ketones often provide the energy and metabolic setup needed for change:
The most dramatic case? Simone lost 90 lbs (40 kg):
As mentioned, the benefits go far beyond fat loss. Mental energy and better sleep are major drivers.
Mona still couldn’t believe her sleep improvement:
“I used to sleep 10 hours and still feel tired. My Garmin confirmed it – sometimes just minutes of deep sleep. Now, for the first time, I had five deep sleep phases in a row.”
Fun Fact
I recently discovered that Navy SEALs and other elite units have been using keto supplements for a while. I only knew about cyclists using versions that cost over $1,000 per dose. Imagine that.
Conclusion: My Experience with r-BHB Ketones
Based on my experience, I can say: they’re worth it.
Yes, they’re not super cheap (about €5-6 per sachet), but much cheaper than they used to be. If you’re willing to invest a few euros a day in yourself, it’s absolutely worth trying.
Just make sure to use the right ketone supplements. Unfortunately, many brands now sell fake or ineffective ketones – exposed in my major ketone review.
Here’s how you can get the real, effective r-BHB ketones straight from the official source at the best price.
