30 Days 2 Shredz: The Fastest, Safest Stubborn Fat Loss Protocol For Getting INSANELY Shredded in Record Time

The wait is officially over for good.

30 Days 2 Shredz: Reprogram Your Mind and Metabolism to Torch Fat, Sculpt Muscle and Create Your Dream Body in 30 Days or Less, my (now) SIXTH international best-selling book, is available for purchase. 

Since the start of 2023, I have been heavily promoting its release and hyping up all the brand-new stubborn body fat loss intel you can expect to find in the book.

I have made promises of possible release dates and had to keep pushing them back (you’ll see why in this article).

But it is finally here.

The blueprint for permanently altering your body composition to become dramatically leaner within 30 days or less… safely and sustainably.

30 Days 2 Shredz, if its instructions are followed to the letter, will give you a dream body beyond your wildest imagination and change you into the best version of yourSELF.

Muscle loss, metabolic dysregulation, hunger cravings, hormonal crashes, or side effects — these things simply don’t have to be a “reality” of achieving sub-10% body fat.

I AM proud to say the days of hardcore bodybuilders and fitness enthusiasts torturing themselves to death for the perfect figure are no longer necessary.

Keep reading to discover why 30 Days 2 Shredz is the most precise and cutting-edge fat loss book the world has ever seen.


“ANOTHER Fat Loss Book!? Come On, Man!”

Long-time readers will be quick to point out 30 Days 2 Shredz is my THIRD book on the subject of fat loss I have published.

Which begs the question: Why would I even waste my time writing about getting shredded yet again when I already have two massively successful books talking about it? 

There’s The Metabolic Blowtorch Diet released in October 2017 with a 4.5/5 star rating across +500 reviews.

156 pages jam-packed with scientific references and detailed explanations to explain – for the first time in my career – the methods behind the madness of my intermittent fasting protocol.

And then I have its sequel, Guaranteed Shredded, self-published exactly two years later.

The most advanced and optimal version of The Metabolic Blowtorch Diet for rapid yet healthy fat loss, clocking in at a mere 20 pages of nothing more than the bare essentials of what one must know.

Not to mention there is an entire main page on my website compiling all of my very best articles on getting leaner (for FREE).

One might think 30 Days 2 Shredz is nothing more than a lazy rewrite of my prior content to make a quick buck and cement myself even further as a health and fitness authority on Amazon.

You wouldn’t be wrong in making this assumption and frankly I had the same thought process as well.

But as anyone who has received an advance copy can attest, 30 Dayz 2 Shredz is not just infinitely better than any other fat loss book or info product on the market.

It is also separate from – AND superior to – both The Metabolic Blowtorch Diet and Guaranteed Shredded.

Here are just a few ways in which the book builds upon the foundation of my prior fat loss books, taps into my 3 decades of bio-hacking for maximum fat burning, and expands upon my tried-and-true principles of fasting, training, supplementation, and surgically precise drug use.

The Extreme Time Limit of Just One Month

All of my prior books were written with the intention of “it takes as long as it takes” when it comes to reaching a certain body fat percentage relative to your starting date and your current level of fitness.

Due to our unique individual biochemistry and genetic profiles as human beings, I was not in a position to make promises such as “Lose 20 Pounds in 20 Days”.

That’s for the magazines in grocery stores, scammy sales letters from Internet marketers, and over-hyped infomercials hawking the newest exercise machine or weight loss supplement.

Over here in the world of Jay Campbell, we have more integrity about the things we say and mean.

I would rather lose customers and money than sell my soul to the demons of the fitness industry.

Now, let me be clear: There is a world of difference between what I promise and what other people promise.

My books made the claim of faster RELATIVE fat loss, meaning you would lose more fat and at a far faster rate when compared directly against conventional fat loss protocols.

What I AM doing with 30 Days 2 Shredz for the very first time is establishing a narrow pre-defined time frame to optimize for maximum stubborn body fat loss.

It is now entirely possible for people to lose a ridiculous amount of body – more than they ever imagined possible – in just a single month if their approach is precise and every variable is accounted for and fully dialed in.

Brand New Changes to the Collective Body of Fat Loss Knowledge

Believe it or not, the esoteric science of accelerated fat loss has changed dramatically since the start of the pandemic-fuelled lockdowns.

Four whole years is indeed a lot of time for advancements to be made with respect to the newest medications, peptides and biomedical technologies now accessible for further enhancement of the body’s fat-burning mechanisms.

Not only have novel mechanisms been discovered and exploited, but we also have published results in our hands thought to be mere science fiction just 4-5 years ago.

Literally, it would have been impossible to publish 30 Days 2 Shredz and make the extraordinary claims you’ll see later in this article.

Sure, the basics of elite-level health and vitality are proven by both bro-science and “nerd” science: Why fasting is good for health, how to preserve muscle in a caloric deficit, optimal macronutrient intake, principles of effective resistance and cardiovascular training, etc.

However… our current knowledge of the newest frontiers in medicine mostly comes from real-world observation and in-field experimentation.

Just in the last two years alone, we’ve had the GLP-1 receptor agonists Semaglutide, Tirzepatide and now Retatrutide enter our lives (along with the media crusade against them).

We got introduced to the amazing power of Tesofensine in enhancing BDNF production and helping us feel AWESOME during extended fasts of 24 hours and longer.

Pharma-grade human growth hormone, when dosed properly, is several orders of magnitude above peptides such as Ipamorelin and CJC-1295 for enhancing the body’s production and secretion of growth hormone.

But in order to use all of these Golden Age agents in unison with one another, it wouldn’t be enough just to write another article or two on my website.

I had to get into CREATOR mode and really flesh out how these new discoveries help us hack our biological systems.

And assuming society doesn’t collapse, rest assured this is just the very beginning.

I AM going all-in on the belief even better tools will emerge following the publication of 30 Days 2 Shredz (and you’ll hear about them first from yours truly).

Addressing the Most Common (And Dangerous) Pitfalls of High-Speed Fat Loss

While my book is truly the be-all-end-all exploration of fat loss in the shortest amount of time possible, I didn’t want the best results at the expense of the worst outcomes imaginable.

There are indeed faster ways to lose fat than what I recommend in 30 Days 2 Shredz, yet they suffer from one or more of the following flaws:

  • Maladaptive metabolic adaptation
  • Dysfunctional hormonal health (ex. loss of libido)
  • Suboptimal thyroid function (ex. lack of appropriate body temperature regulation)
  • Damaged mental health (i.e. eating disorders such as orthorexia, negative image of oneself via body dysmorphia, etc.)
  • Extreme hunger cravings
  • Boredom due to repetitive and restrictive nature of a diet/program (leading to lower compliance)
  • Unsustainable lifestyle habits (missing out on events with family and friends, complete diet inflexibility, etc.)
  • Muscle tissue loss due to inappropriate macronutrient use (as evidenced in crash starvation diets and extended water fasts)
  • Use of toxic drugs such as DNP

Publishing my book any earlier than right now would have been impossible without at least one of the above inevitably happening.

And it only takes just one of these flaws to manifest the hellish yet inevitable rebound weight gain that puts most dieters even further behind compared to where they started.

But the promises I make in the book, including the absolute certainty you will not experience a single side effect I just listed, are no longer science fiction.

They are a REALITY, and the next point will show you exactly why.

In-Depth Case Studies, Data, and Proof From People Just Like You

My previous books would always use yours truly as a testimonial to vouch for the effectiveness and safety of what I preached.

For good measure, I would include a few written words of praise from other people, and if I was really in a good mood I would include one before-and-after photo transformation.

But despite the tens of thousands of book reviews and emails I privately get from people saying my prior fat loss books changed their lives, I was selling myself short.

And as much as I despise scientism, the claims I make in 30 Days 2 Shredz are more extraordinary compared to anything I have ever said before.

Therefore, extraordinary evidence was needed to back up my marching orders… especially given the end result will ultimately be staring back at you in the mirror.

Yoda’s famous quote “do or do not, there is no try” is sage wisdom when it comes to evaluating how powerful any fat loss approach is.

So I did what I never did before, and had my private VIP Mastermind members beta-test my findings for the entire of 2023.

They ran at least one cycle of the 30 Days 2 Shredz program, if not multiple cycles.

They carefully documented and tracked every single thing they did, with full transparency about their successes and their failures.

I’ll say this… even in the most imperfect approach I saw, the results they achieved in merely four weeks are unlike anything the world has ever seen for fat loss in the fastest and healthiest way possible.

(NOTE: All of these transformations are documented in Chapter 10 of the book, as discussed later on in this article)

And yours truly was a part of this testing as well, as I got myself into my best condition for my 52nd birthday on February 24 of this year.

Myself and my VIP Mastermind members achieved 10x what was possible with the most advanced strategies found in Guaranteed Shredded.

All of us are official members of the new upper class of super-lean athletes, and now it’s time to see how you too can join the club.

What’s Inside “30 Days 2 Shredz”?

30 Days 2 Shredz clocks in as a 418-page behemoth, making it more than twice the length of The Metabolic Blowtorch Diet and Guaranteed Shredded put together.

Each chapter would require its own article if I were to provide a summary because of how much content has been jammed into the book.

And believe me when I say this book has been massively shortened down — entire bonus chapters and sections had to be completely removed and instead released as future products I AM in the middle of developing.

So without further ado, here is exactly what you’re going to get when you read 30 Days 2 Shredz from start to finish…


✔️ Why loving and trusting yourSELF is the true key to getting shredded (the most effective training methods, peptides, hormones, and supplements will NEVER overcome self-sabotage and feelings of unworthiness)

✔️ My personal journey with following the 30 Days 2 Shredz protocol exactly as outlined in the book (dates, starting photos, photos halfway through the program, ending photos, commentary… this is probably the first time I have ever documented any of my biohacking experiments so religiously)


✔️ The exact criteria to determine whether you are a beginner, advanced, or elite level dieter (your experience with fasting, weightlifting, supplement/peptide use, and hormonal optimization will dictate how you set up the program. Lie to yourself about this and you WILL sabotage your success before you’ve even started)

✔️ Why some people may find the beginner level of 30 Days 2 Shredz to be too challenging (and the two ways this can be easily fixed)


✔️ How my long-held philosophy of “insulin-controlled living” has become obsolete in the 2020s (and what I AM going to replace it with going forward in all my future articles, videos, webinars, courses, and books)

✔️ A little-known industry-insider secret about why the ketogenic diet leads to damaged insulin metabolism (this goes all the way back to the late 1990s when the diet was first tested on famous fitness influencers, both household names you’d recognize and names only the true OGs will know of)

✔️ A high-end spreadsheet to document and record every single factor you will be tweaking in the 30 Days 2 Shredz program (a resource that was ONLY available to VIP Mastermind members paying me $25,000 a year is now it’s yours to use in all its glory)

✔️ My final stance about the “debunked” myth of body somatotypes and why they matter in dictating your approach to nutrition (things like your insulin sensitivity and genetic predisposition to losing fat and/or building muscle are more affected by your somatotype than you think. Fortunately for you, one’s predominant somatotype can change over time with the right diet and training)

✔️ Step-by-step instructions for calculating your macronutrient needs, the BEST macronutrient sources to eat for fully optimized health, and a FREE nutrition calculator to make the process even easier (you’ll discover why I actually go out of my way to recommend AGAINST eating chicken breasts and turkey, a stance that’s gotten me into a lot of trouble with the bodybuilding community at large)


✔️ 29 fat loss supplements, peptides, hormones, research chemicals, and medications to make dramatic fat loss within 30 days humanly possible and effortless (each one is broken down into what it is, how it works for fat loss, why I recommend it for the 30 Days 2 Shredz program, who should and shouldn’t use it, how to dose it precisely, and where to buy it)

✔️ The ultra-cheap supplement almost EVERY person fasting forgets to take, which explains why they have fatigue and brain fog (even I am guilty of not explicitly talking about this in my prior two books, so it’s high time I cleared the air about this supplement)

✔️ Six important milestones a beginner-level dieter must achieve before they can even think about using advanced supplements (Milestone #1 alone is enough to stop 80% of all dieters from ever tapping into the game-changing research chemicals known to make a world of difference in the speed of fat loss)

✔️ Why Phentermine has an undeserved reputation as a “dangerous” weight loss drug (I’ll give you the real scoop behind the “fen-phen” diet craze that killed people in the 1990s and early 2000s, plus I’ll show you how to avoid the side effects people commonly experience when using Phentermine)


✔️ The importance of “positive muscular failure” (PMF) for both muscle gain and fat loss (no other training methodology will produce bigger and stronger muscles than PMF-style training, and you’ll se how 2 working sets for a muscle group in one training session is all you require to build a world-class physique when they are performed with correct technique and maximum intensity)

✔️ Why taxing all three energy systems within the human body is the only way to maximize the fat loss benefits of resistance training (this gets into some harsh truths the low-rep “5×5” bros don’t want to acknowledge, but they should as it explains why the majority of its proponents have exactly the same physique year after year)

✔️ How maximal muscle preservation, and even muscle gain, is entirely possible with far lighter weights than you think (I’ll share some insights about legends like Jay Cutler, Mike Mentzer, and Dorian Yates you won’t believe are true… unless you’re someone like me who personally knows these people, because you WILL NOT see this kind of intel in a fitness magazine or an interview)

✔️ The RIGHT types, duration, and intensity of cardio to do for injury-free fat loss (most people who do cardio end up catabolizing muscle or setting themselves up for joint replacements later down the road… if you’re in your 30s and above, follow my instructions to the letter and you’ll save yourself an unpayable hospital bill)


✔️ My unique approach to refeeds and carbohydrate cycling that prevents metabolic rate downregulation and muscle catabolism, all while maintaining an extreme caloric deficit and enough energy to lift heavy weights at maximum intensity (I’ll show you what it means to selectively manipulate your carbs around your workout window for the best training and body composition results possible)

✔️ Why the “bros” are right when it comes to eating at least 4-6 meals a day for maximum muscle gain (there are serious downsides to just eating 1-2 meals a day for intense resistance training not realized by most long-term fasters until it is already too late)

✔️ How HIIT cardio ends up being the #1 cause of muscle tissue loss on fat loss diets (all it takes is a single shift in timing for HIIT to turn your body into a fat-burning machine without your muscle tissue being affected in any way)

✔️ How the fitness community was brainwashed into believing people can lift heavy weights in a fasted state (you’ll see exactly what happens to everyone who is dumb enough to do this… if you want to ignore my advice at your own peril, feel free to do so)

✔️ A FREE 3-day full-body weightlifting program based on the principles of PMF (included are exact exercises, sets, reps, rest periods, how and when to increase the weight, and some Jay Campbell wisdom for select exercises in the form of explaining proper lifting technique and video demonstrations)


✔️ A deep dive into the numerous biological processes leading to the health benefits of fasting, especially the sped-up fat loss (Hunter Williams provides an hour-by-hour breakdown of the process of fasting, showing you why it forces your body to preferentially tap into your body fat stores and is way more powerful than “just inducing a calorie deficit”)

✔️ Laying down the hammer once and for all about what does and DOES NOT count as real fasting (way too many people take something so simple and screw it up by making it too complicated to the point where it’s no longer fasting… read this part and you’ll avoid 99% of the misinformation on the Internet about this topic)

✔️ How long you should be fasting depending on whether you are a beginner, advanced, or elite level dieter (I include specific meal plan examples for each level so you know exactly when to eat, if at all, how much you should be eating, and the best food choices to make fasting much easier to endure)

✔️ A collection of my favorite hacks to get the most out of fasted cardio (bodybuilders will crap their pants at the mere idea of doing as much cardio as I recommend, but in the long run you WILL become more insulin-sensitive and have a much higher tolerance for carbohydrates… a necessity for when you finish losing fat and transition towards building muscle)


✔️ The benefits of going “off-plan” once a week during an extreme diet like 30 Days 2 Shredz for your mind and your body (the benefits are not just psychological… you’ll see why occasionally splurging on a well-designed cheat meal is physiologically crucial to prevent fat loss from coming to a complete standstill)

✔️ Why the weekends are ironically the GREATEST opportunity for the highest rate of fat loss per unit of time (if you’re a Spartan who wants to be 100% on point for the entirety of the program, I’ll show you how to use your Saturday and Sunday to tap into a fat loss mechanism that science and medicine have been unable to replicate with pharmaceuticals (YET))

✔️ Strict guidelines to avoid turning unavoidable meals with friends and family into disasters ruining all the fat loss progress you made during the week (I won’t ask you to bring a Tupperware container to a restaurant, but there are certain things you absolutely should not consume and certain combinations of foods you should stay away from)


✔️ A weekly schedule putting together everything you’ve seen in the last 2 chapters (almost everyone who previewed the book understood immediately what to do without this chapter… but if you’re lost, have no fear because I wrote it to leave no stone unturned and make things as easy as possible for you)

✔️ Monthly calendars to show you what your 30-day run of 30 Days 2 Shredz will look like depending on whether you’re a beginner, advanced, or elite level dieter (each calendar is formatted so you can print it off, place it on the wall, and know exactly what to do each day… and what’s coming up ahead in the near future)


✔️ Why it is mission-critical for anybody following an extreme fat loss diet to take a 1-2 planned “maintenance” break (believe it or not, this is increasingly becoming the #1 place where people self-sabotage many weeks and months worth of fat loss progress… in some cases I’d even argue it’s more important to get this part right than the 30-day program itself)

✔️ How to properly adjust your diet, training, and supplementation for your maintenance break depending on your body somatotype and body fat percentage (if you want to maintain your new physique for far longer than your planned break, I’ll show you how to do that too… just know your maintenance break is NOT an excuse to pig out and be lazy!)

✔️ The adjustments I recommend you make when you run your second cycle of 30 Dayz 2 Shredz and beyond (as you get leaner, you’ll need to tweak a few variables in order to preserve as much muscle mass as possible and prevent fat loss slowdown)

✔️ A comprehensive mini-guide containing every single way you can troubleshoot major stalls in weight loss and body composition (believe me when I say there are a LOT of variables and options provided, but don’t get overwhelmed… as you finish the guide, you’ll realize it is NOT impossible to overcome serious fat loss plateaus)


✔️ FOUR ultra-detailed case studies demonstrating how safe and effective 30 Days 2 Shredz is when utilized to its maximum potential (the stories are quite diverse with respect to age and training background, but all of them show how reproducible and life-changing these transformations can be)

✔️ How a formerly obese healthcare executive slimmed himself down the “long and hard” way, but then went from 15% body fat to 8% body fat in the span of 45 days at the young age of 49 years old with my program (that’s a 50% reduction in his total body fat within a month and a half… a stupidly impressive transformation)

✔️ Why an elite-level former Division 1 NCAA football player calls 30 Days 2 Shredz “the undisputed GOAT of any fat loss program ever given to mankind” (this is coming from someone who trained consistently and intensely as a NATURAL from ages 12-28 and only started using exogenous testosterone alone at 29 years old… a person who has truly seen and tried it all in the fitness industry and is already genetically gifted)


✔️ A diabolically shrewd way to improve the rate of fat loss per unit of time at the highest level to ludicrous speeds (it’s shockingly simple yet adds many more hours of hardcore fasting to your week)

✔️ How to fast for even longer than what is scheduled for elite-level dieters and reach the absolute peak of maximal fat loss (this is NOT for everyone… even for the most hormonally optimized and neuromuscularly efficient among us, there are very tight limits on how often and how long to use this hack so you don’t eat away at muscle tissue)

✔️ My highly-tested “damage control protocol” for MASSIVE eaters who want to eat ridiculous cheat meals while staying ultra-lean 365 days a year (I’ll hook you up with the exact dietary guidelines, pre- and post-meal training programs, and supplement regimens I use to make the excess thousands of calories consumed work in the favor of muscle gain instead of fat gain)

✔️ The newest piece of non-invasive biomedical technology showing incredible promise for targeting fat burn AND muscle growth at the same time (Monica and I tested this ourselves and radically reduced intra-abdominal body fat while improving lower ab definition at the same time… with only one 30-minute session a week between May and October of last year)

But before you get too excited and pick up a copy of 30 Days 2 Shredz, I have some final words for you…

Who “30 Days 2 Shredz” is NOT For

As much as I want every single person in the world to have 30 Days 2 Shredz on their bookshelf as a lifelong fat loss manual, there are two important caveats to make for would-be buyers.

#1 – The more seriously you take this process and the more of my advice you follow, the more fat you will lose and the easier it will be to stay 100% on plan.

In order to manifest all of the extraordinary claims I make in the book to their maximum level and effect, STRICT ADHERENCE to the supplements, medications, resistance, and cardiovascular training protocols is required.

Not everyone can or will follow all of the instructions in my book, and that’s OK.

It’s the main reason why I divide readers into 3 separate tiers from the first chapter… after all, everybody starts off with differing levels of discipline, athleticism, and financial commitment.

#2 – If you are a highly inflamed dumpster fire who is incapable of intermittent fasting and refuses to allow themselves to become “fast adapted”, 30 Days 2 Shredz is not the program for you. 

Anybody in this camp is likely over 25-30% body fat, untrained, drinking too much alcohol, and NOT loving and trusting themselves.

Believe me when I say you will fail miserably if you are using this program to get in beach shape for a trip to the tropics next month… you will likely do more harm than good.

In this situation, my recommendation would be to spend the next 3-6 months learning and practicing the basics of what is found in The Metabolic Blowtorch Diet before you take on the beginner level of 30 Days 2 Shredz.

Since your microbiome (i.e. gut) is a sea of pathogens screaming to be fed, you will find fasting to be a challenge at first.

And it will be very difficult if not impossible to start doing fasts for 24 hours and longer.

That’s not to say anybody with enough fortitude and an iron will can eventually learn to become fast-adapted… but perhaps an easier program will be the better choice for an inflamed dumpster fire.

30 Days 2 Shredz will still be here and alive when you are ready. 😉
