Nutrient dense bioavailable protein – the secret to optimal body composition


The dietary tug-of-war between low fat and low carb has often overshadowed a macronutrient deserving of spotlight: protein. However, it’s not just about the quantity, but also the quality and bioavailability of protein we consume. This article sheds light on the protein leverage hypothesis, emphasizing the significance of protein bioavailability.

The Protein Leverage Hypothesis (PLH) Defined

The Protein Leverage Hypothesis (PLH) suggests that humans instinctively consume food until they meet their amino acid needs. In simpler terms, insufficient protein intake can drive our bodies to crave foods high in carbohydrates and fats, searching for those vital amino acids. The ramifications? Consuming protein sources with low bioavailability may lead us down the path of overeating and subsequent weight gain.

Bioavailability: Beyond Just Protein Intake

Animal-based versus plant-based sources of protein

Bioavailability refers to the proportion of protein that can be readily absorbed and utilized by the body. Not all protein sources are created equal. Particularly, plant-based protein sources, while beneficial in many aspects, often have lower bioavailability compared to their animal-based counterparts. This means, individuals relying solely on plant-based proteins may need to consume even more to meet their requisite protein needs.

Protein Ratios and Their Importance

The focus should not only be on the quantity of protein but also its quality. Traditional diets, rich in bioavailable protein, ensured a state of satiety, thus preventing overeating. However, as modern diets introduce more plant-based sources, understanding the bioavailability becomes paramount.

Re-evaluating Protein Recommendations

Current guidelines suggest a range of 0.8-1.0 grams of protein per kilogram of body weight. However, when bioavailability is considered, especially with a plant-centric diet, this range may not suffice. Protein metabolism experts highlight the need to adjust intake based on protein source and its respective bioavailability.

Could low bioavailability of our protein sources be a contributor to today’s obesity concerns? Researchers like David Raubenheimer and Stephen Simpson hint at this. Their work suggests that our body’s relentless quest for protein might cause us to overconsume calories, especially when our primary protein sources are less bioavailable.

The Modern Diet Conundrum

Protein is the master macro nutrient. Too much protein = weight loss, too little = weight gain

In questioning the conventional wisdom that a plant-based diet is inherently beneficial for human health, I want to highlight a few points. First, plants have their own survival mechanisms, which often involve producing natural pesticides and toxins to deter predators. This could potentially have implications for human health.

Another important aspect to consider is the bioavailability of plant-based proteins, which is generally lower compared to animal-based proteins. What this means is that you might need to consume larger amounts of plant foods to meet your protein requirements. This increased consumption can lead to a higher caloric intake, which, in turn, could result in unintentional weight gain.

So, plant-based diets come with their own set of challenges. These include anti predation toxins that predispose you to autoimmune pathologies via the Leaky Gut Syndrome, as well the need for careful planning to make sure you’re getting adequate protein without exceeding your caloric needs.

Conclusion: A Renewed Focus on Bioavailable Protein

Reevaluating the bioavailability of your protein sources

Our exploration underscores the importance of not just consuming protein, but also ensuring it’s from a bioavailable source. For those finding themselves constantly hungry or snacking, reconsider your protein sources. By choosing highly bioavailable proteins, you may experience reduced cravings and a boost in overall health.
