I will work on creating actionable steps that can be personalized for your unique nutritional needs.


This blogs mission is to elevate your understanding on how to effectively harness the power of protein, not just as a nutrient, but as a vital component of a holistic approach to health, vitality and longevity.


Protein Distribution: More Than Muscle

Protein's journey in our bodies is a testament to its versatility. While we often prioritize its role in muscle building (only thinking about it as a muscle building tool), an astonishing 50% of dietary protein supports the function of our abdominal organs and 40% is pivotal in metabolic processes. It's honestly a powerhouse for energy, urea synthesis, and even neurotransmitter production (think brain health and function); side note, high amounts of protein in the morning, for breakfast, is a great way to enhance brain function. With 50% of dietary protein going to the organs and 40% in metabolic processes this only leaves a modest 10% for muscle protein synthesis; yet, this is where BCAAs shine. Bypassing the liver to a significant extent, up to 80% of these amino acids directly fuel our muscles.


Protein plays a critical role in maintaining the vitality of our internal ecosystem. The liver, for instance, is a hub of protein use, engaging in detoxification, hormone production, and other vital processes that sustain life. Similarly, the gut utilizes protein to maintain its integrity, supporting a robust immune system and facilitating the absorption of nutrients. BCAAs, particularly leucine, isoleucine, and valine, sidestep the liver's filtration and are preferentially shuttled to skeletal muscles, where they contribute to repair, growth, and energy supply during physical exertion (leucine is key, more on this later). This selective distribution underscores the body's intricate system of prioritization, ensuring that each protein we consume serves multiple, critical roles, reinforcing the notion that protein is vital not only for building muscle but for our overall well-being.


The Role of Isotope Labeling in Protein Tracking

Advanced research techniques, such as isotope labeling, have allowed scientists to trace the intricate pathways of protein within the body, shedding light on the mechanisms of muscle building. Through these methods, it's been established that high-quality proteins—typically yielding about 3 grams of leucine per 25-gram portion—play a pivotal role in muscle protein synthesis. This has challenged the longstanding belief in a rigid 'leucine threshold.' Instead, research shows that while cells do require a certain level of leucine, this amino acid alone does not limit the capacity for protein synthesis.


As we grow older, the efficiency with which our bodies synthesize protein can decrease, a phenomenon not due to a reduced capacity to utilize protein but rather a state known as anabolic resistance. This condition suggests that aging muscles require higher quantities of protein for optimal function and growth, emphasizing the need for more protein-rich meals throughout the day. Moreover, each meal should be sufficiently rich in essential amino acids, particularly leucine, to overcome this age-related anabolic resistance. Thus, anabolic resistance in the elderly doesn't spell the end of muscle growth; it simply calls for a more strategic approach to protein consumption, ensuring that every meal contributes effectively to the body's anabolic needs. Everyone, especially as we age, should prioritize getting high amounts of protein at breakfast (ends a fast), after a workout (recovery and muscle need it) and at dinner (the body grows at night).


Muscle Protein Anabolism: Striking a Balance

Understanding muscle growth requires us to delve into the intricate process of protein accretion. It's not merely the creation of new proteins but the dynamic equilibrium between muscle protein synthesis (MPS) and muscle protein breakdown (MPB) that dictates growth. Honestly, the intricate process of hypertrophy hinges on this balance. Sustaining a higher rate of MPS relative to MPB over time ensures the accumulation of muscle mass (i.e. Hypertrophic gains).


This delicate balance is orchestrated by the mammalian target of rapamycin (mTOR), a crucial cellular pathway that integrates signals from mechanical tension—induced by lifting weights—insulin-like growth factor 1 (IGF-1), and the availability of essential amino acids, notably leucine. When activated, mTOR paves the way for increased MPS, setting the stage for muscle growth and repair. However, your fuel has to be on par and protein levels must be adequate or MPB will occur.


Post-exercise, the body enters a catabolic state where muscle proteins are broken down. However, with the right stimulus—particularly resistance training and adequate nutritional support—mTOR becomes activated, shifting the balance in favor of anabolism over catabolism. This is not just about recovery; it's about priming the muscles to adapt and grow stronger in response to the stimulus provided. Therefore, both workout intensity and nutrition are critical, with protein intake and its timing playing pivotal roles in ensuring that mTOR can do its job effectively, promoting growth. One should ensure that each training session they are taking their working sets to 1-2 reps of failure, while maintaining eating habits of 1g per 1 pound of bodyweight (can even be more).


Protein Intake: One Size Does Not Fit All

The realm of protein intake is not one-size-fits-all, particularly for those who lead an active lifestyle or engage in regular athletic training. The standard recommendation I see for protein intake, ranging from 0.73 to 1 gram per pound of body weight (the RDA is even way lower), may suffice for the general population not training. However, for athletes, active gym goers and/or individuals with considerable muscle mass, this guideline often falls short of meeting their enhanced nutritional needs.


Athletes striving for peak performance and muscle maintenance must adjust their protein consumption accordingly. Not only do they require more protein to repair and build muscle tissue, but their bodies also need additional amino acids to support the increased metabolic demands of intense training. For such individuals, protein needs may escalate to 1.2-1.5 grams per pound or more, contingent on their training regimen and body composition goals. As if quantity wasn’t hard enough, timing protein intake plays a role as well; although, timing is secondary to total protein intake.


Timing is also a critical component of protein intake. Strategic consumption of protein at key times throughout the day can significantly amplify muscle protein synthesis. A robust serving of protein upon waking helps reverse the muscle catabolism that occurs during the overnight fast. Post-workout, a substantial protein meal accelerates recovery by replenishing amino acid reserves and kickstarting repair processes. Lastly, a dose of protein before bed can provide a sustained release of amino acids, aiding muscle recovery and growth during sleep.


For those seeking to sculpt a lean, muscular physique, higher protein intake coupled with strategic timing is not just beneficial; it's essential. It ensures that muscle tissues are continuously fed with the building blocks they need, not only to recover from the day's exertions but also to prepare for the physical challenges ahead.


Calorie Deficits and High Protein Requirements

When faced with a calorie deficit, one must understand the DEMAND for protein consumption is HIGHER than normal. When calories are pared down, each nutrient plays a crucial role, but it's protein that MUST take center stage. The aim is to shield muscle mass from the catabolic effects of a calorie deficit, ensuring that the body retains its muscular integrity even as it sheds fat.


Frequent protein-rich meals become not just a recommendation but a necessity in such scenarios. They are the bulwark against muscle loss, providing a constant influx of essential amino acids needed to sustain muscle protein synthesis. This approach transcends the goal of fat reduction, focusing instead on preserving and fortifying the body's lean tissue. For those who eat in a deficit and eat regular to low protein amounts, per body mass, they lose high amounts of lean muscle mass (not good).


A key player in this process is leucine, an amino acid that serves as a potent trigger for muscle building. By spreading protein intake across multiple meals, you create an environment where leucine levels in the blood remain consistently high. This steady state facilitates ongoing muscle maintenance, helping to ensure that even in the midst of a calorie deficit, the body's muscle-building machinery remains well-fueled and operational.


In essence, protein in a calorie-restricted regimen isn't just about meeting a daily quota; it's about strategic timing and distribution to protect against muscle loss.


Protein's Unlimited Potential

The long-standing myth that our bodies can only utilize a finite amount of protein in one sitting has been debunked by modern science; I have argued with people over this myth numerous times over my 20-year career but have never had a study to support, until now. A groundbreaking study in Cell Reports (2) have illuminated the reality that there is no upper ceiling when it comes to protein's potential for muscle synthesis. This revelation is reshaping how so-called “experts” view protein consumption, especially in relation to exercise and recovery.

When we consume protein in large quantities, particularly after a strenuous workout, our bodies do not simply discard the excess. Instead, they harness this nutrient-dense bounty, channeling amino acids to the muscles where they're urgently needed for repair and growth. This process is not just about replenishing what we've expended; it's about capitalizing on the anabolic window, the critical period post-exercise when our muscles are primed to absorb nutrients and initiate the rebuilding phase.


This efficient use of protein is evidenced by the surge of amino acids in the bloodstream following a high-protein meal or shake. These amino acids are not aimlessly floating in our circulatory system but rather on a mission to boost muscle protein synthesis. As such, indulging in a protein-rich diet, particularly after workouts, can significantly enhance our body's recovery process and contribute to greater gains in muscle mass!! Let’s Go!!


The practical takeaway from these findings is clear: don't hold back on protein, especially when your muscles are in a state of recovery. By doing so, you're not only feeding your body's immediate needs but also laying the foundation for stronger, more resilient muscle growth over time. For me, I choose about 40-50g of fast absorbing grass-fed Whey Protein Isolate directly after my workout and then 3 eggs and 5oz of ground grass-fed beef shortly after that. The mixture of fast then slow ensures a longer anabolic window of feeding!



Protein stands as a cornerstone of nutrition, not just for those sculpting their physique or enhancing athletic prowess, but for anyone aspiring to optimal health and well-being; protein plays a multitude of roles in the body. It is the lifeblood of organ functionality, the building block of muscular development, and the fuel that powers our metabolic processes.


Our journey through the world of protein has revealed its capacity to influence muscle anabolism, underscored the importance of leucine in triggering muscle growth, and highlighted the necessity of consuming ample amounts post-workout to leverage protein synthesis. We've also seen how protein intake isn't a one-size-fits-all scenario; it's a variable that should be customized according to individual needs, lifestyles, and goals.
