Fundamentals

Many individuals experience a subtle yet persistent sense of imbalance, a feeling that their body’s internal rhythm has shifted. Perhaps it manifests as a lingering fatigue that no amount of rest seems to resolve, or an unexplained difficulty managing weight despite consistent effort.

Others might notice mood fluctuations, a diminished drive, or a struggle with mental clarity that was once effortless. These experiences are not merely isolated symptoms; they often serve as quiet signals from a deeply interconnected system within the body ∞ the endocrine network. Understanding these signals, and the biological underpinnings that create them, represents a powerful step toward reclaiming vitality and function.

The endocrine system operates as the body’s sophisticated internal messaging service, utilizing hormones as its chemical couriers. These hormones travel through the bloodstream, delivering instructions to various organs and tissues, orchestrating everything from metabolism and growth to mood and reproductive health. When this intricate communication network encounters disruptions, the effects can ripple throughout the entire physiological landscape, leading to the very symptoms many individuals describe.

The Dietary Fat Connection

Dietary fats are not simply sources of energy; they are fundamental building blocks and critical signaling molecules within the body. Their quality and balance directly influence cellular integrity and the efficiency of hormonal communication.

When the intake of dietary fats becomes imbalanced over time, particularly with an overabundance of certain types and a deficiency of others, the long-term resilience of the endocrine system can be significantly compromised. This is not a matter of simple caloric excess alone; the specific types of fats consumed play a profound role in shaping the body’s internal environment.

The quality of dietary fats profoundly influences the body’s internal communication network, affecting hormonal balance and cellular function.

Understanding Different Fat Types

Dietary fats are broadly categorized into several types, each with distinct biological roles. Saturated fatty acids (SFAs) are typically solid at room temperature and are found in animal products and some tropical oils. Unsaturated fatty acids, which include monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs), are generally liquid at room temperature.

MUFAs are abundant in olive oil and avocados, while PUFAs are found in fatty fish, nuts, and seeds. PUFAs are further divided into omega-3 and omega-6 fatty acids, which are considered essential because the body cannot produce them and must obtain them from diet.

A less desirable category includes trans fatty acids, often created through industrial processing, which have been widely recognized for their detrimental health impacts. The balance and proportion of these fats in one’s diet directly influence the composition of every cell membrane in the body, which in turn dictates how cells receive and respond to hormonal signals.

Cellular Sensitivity and Hormonal Reception

Every cell in the body is encased by a cell membrane, a dynamic barrier composed primarily of lipids and proteins. This membrane is not merely a passive boundary; it is an active participant in cellular communication, housing numerous receptors that act as docking stations for hormones. The fluidity and integrity of these membranes are directly influenced by the types of fats incorporated into their structure.

An imbalance in dietary fat intake, particularly an excess of saturated and trans fats, can alter the lipid composition of cell membranes, making them less fluid and potentially impairing the function of hormone receptors. When receptors are compromised, hormones struggle to deliver their messages effectively, leading to a state of cellular insensitivity.

This means that even if hormone levels are adequate, the cells may not be “hearing” the instructions, resulting in a functional deficiency at the tissue level. This cellular resistance is a fundamental mechanism underlying many endocrine dysfunctions.

The Inflammatory Cascade

One of the most significant long-term effects of imbalanced dietary fat intake on endocrine resilience is the promotion of chronic, low-grade inflammation. This inflammatory state is not the acute, localized response to injury or infection, but rather a systemic, persistent cellular irritation that can silently undermine metabolic and hormonal health.

An excessive intake of omega-6 fatty acids, particularly from processed vegetable oils, coupled with an insufficient intake of anti-inflammatory omega-3 fatty acids, shifts the body’s biochemical pathways toward producing pro-inflammatory signaling molecules. These molecules, known as eicosanoids, are derived from fatty acids and play a crucial role in regulating inflammation. When the balance is skewed, the body exists in a perpetual state of low-level alert.

Oxidative Stress and Cellular Damage

Chronic inflammation often goes hand-in-hand with increased oxidative stress. This occurs when there is an imbalance between the production of reactive oxygen species (ROS) and the body’s ability to neutralize them with antioxidants. High dietary fat intake, especially of unhealthy fats, can increase mitochondrial-generated ROS, leading to cellular damage. This damage can directly affect endocrine glands, impairing their ability to synthesize and secrete hormones, and further compromise the sensitivity of target cells to these hormones.

The cumulative effect of inflammation and oxidative stress creates a hostile environment for the delicate endocrine glands and their signaling pathways. Over time, this sustained assault can diminish the glands’ capacity to function optimally, reducing the overall resilience of the hormonal system to respond to daily stressors and maintain homeostasis.

Initial Hormonal Disruptions

The immediate impact of imbalanced dietary fats can be observed in key hormonal systems. One of the earliest and most widespread disruptions involves insulin sensitivity. Insulin, a hormone produced by the pancreas, is responsible for regulating blood glucose levels by facilitating glucose uptake into cells. When cells become resistant to insulin’s signals, blood glucose levels remain elevated, prompting the pancreas to produce even more insulin. This state, known as insulin resistance, is a hallmark of metabolic dysfunction.

Research consistently shows that diets rich in saturated fats significantly worsen insulin resistance, while diets higher in monounsaturated and polyunsaturated fatty acids can improve it. This is partly due to the changes in cell membrane composition, which affect the insulin receptor’s ability to bind insulin and initiate the appropriate cellular response.

Beyond insulin, other hormones begin to show signs of strain. Leptin, an appetite-regulating hormone secreted by fat cells, can also become dysregulated. Elevated levels of saturated fatty acids can induce leptin resistance, meaning the brain no longer accurately receives the satiety signals from adipose tissue. This can contribute to persistent hunger and weight gain, creating a vicious cycle that further stresses the endocrine system.

Even thyroid hormones, which govern metabolism and energy expenditure, can be indirectly influenced by dietary patterns that affect leptin signaling. The intricate web of hormonal interactions means that a disruption in one area can cascade, affecting seemingly unrelated endocrine functions over time. The body’s systems are always in conversation, and dietary fats influence the clarity of that dialogue.


Intermediate

When the body’s internal communication system, the endocrine network, faces prolonged challenges from imbalanced dietary fat intake, the subtle disruptions observed in the initial stages can progress into more pronounced clinical manifestations. This section explores the specific mechanisms by which chronic fat imbalances necessitate targeted interventions, including hormonal optimization protocols and peptide therapies, to restore systemic balance and resilience.

The body, much like a complex orchestra, requires each section to play in harmony; when certain instruments (hormones) are out of tune due to dietary influences, a skilled conductor (clinical intervention) can guide them back to synchronicity.

Adipose Tissue as an Endocrine Organ

Adipose tissue, commonly known as body fat, is far more than a passive storage depot for excess energy. It functions as a highly active and dynamic endocrine organ, secreting a diverse array of signaling molecules known as adipokines. These adipokines play critical roles in regulating metabolism, inflammation, and even reproductive function.

In a state of balanced fat intake and healthy adipose tissue, adipokines like adiponectin contribute to insulin sensitivity and anti-inflammatory processes. However, when dietary fat intake is chronically imbalanced, particularly with an excess of saturated and trans fats, adipose tissue can become dysfunctional.

This dysfunction leads to altered secretion profiles of adipokines, often characterized by reduced adiponectin and increased levels of pro-inflammatory cytokines such as tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6). This shift contributes significantly to systemic low-grade inflammation and exacerbates insulin resistance.

Impact on Steroid Hormone Synthesis

Dietary fats provide the raw materials for the synthesis of steroid hormones, including testosterone, estrogen, progesterone, and cortisol. Cholesterol, derived from dietary fats and synthesized in the liver, is the precursor molecule for all steroid hormones. An imbalanced fat intake can affect the availability of appropriate precursors or the efficiency of the enzymatic pathways involved in hormone production.

For instance, a diet severely deficient in healthy fats can limit cholesterol availability, potentially impairing steroidogenesis. Conversely, an excess of certain fats, particularly those that promote inflammation, can disrupt the delicate enzymatic cascades required for balanced hormone synthesis. This can lead to imbalances in sex hormones, affecting both male and female reproductive health, and influencing stress hormone regulation.

Insulin and Leptin Resistance Deep Dive

The interplay between dietary fats, insulin, and leptin is central to metabolic and endocrine resilience. Chronic consumption of diets high in saturated and trans fats directly contributes to the development of insulin resistance. This occurs at the cellular level, where the altered lipid composition of cell membranes reduces the efficiency of insulin receptor signaling. The body compensates by producing more insulin, leading to hyperinsulinemia, which itself can drive further metabolic dysfunction and inflammation.

Similarly, leptin resistance emerges as a significant consequence of imbalanced fat intake. Leptin, secreted by adipocytes, signals satiety to the brain. When adipose tissue becomes dysfunctional due to chronic exposure to unhealthy fats, the brain’s ability to respond to leptin diminishes. This leads to a persistent feeling of hunger, reduced energy expenditure, and a propensity for weight gain, creating a feedback loop that further stresses the endocrine system and metabolic pathways.

Chronic consumption of unhealthy fats impairs cellular responses to insulin and leptin, driving metabolic dysfunction and persistent hunger.

The Hypothalamic-Pituitary-Gonadal Axis Disruption

The Hypothalamic-Pituitary-Gonadal (HPG) axis is a complex neuroendocrine pathway that regulates reproductive function and sex hormone production in both men and women. Imbalanced dietary fat intake can significantly disrupt this axis.

In men, obesity, often driven by chronic high-fat diets, is associated with altered adipokine secretion and increased aromatase activity in adipose tissue, leading to higher estrogen conversion from testosterone. This can result in lower circulating testosterone levels, impacting libido, muscle mass, bone density, and mood. The HPG axis attempts to compensate, but chronic disruption can lead to functional hypogonadism.

For women, imbalanced fat intake and subsequent metabolic dysfunction can contribute to conditions like Polycystic Ovary Syndrome (PCOS), characterized by insulin resistance, hyperandrogenemia (excess androgens), and menstrual irregularities. Adipose tissue dysfunction in central obesity can lead to higher androgen levels, even without a PCOS diagnosis. The delicate balance of estrogen, progesterone, and testosterone is profoundly sensitive to dietary fat quality and metabolic health.

Targeted Hormonal Optimization Protocols

When dietary and lifestyle interventions alone are insufficient to restore endocrine balance, targeted hormonal optimization protocols can play a crucial role in recalibrating the system. These interventions are designed to address specific hormonal deficiencies or imbalances that have arisen, often exacerbated by long-term dietary fat dysregulation.

Testosterone Replacement Therapy Men

For middle-aged to older men experiencing symptoms of low testosterone, such as reduced energy, decreased libido, and changes in body composition, Testosterone Replacement Therapy (TRT) can be a vital intervention. A standard protocol often involves weekly intramuscular injections of Testosterone Cypionate (typically 200mg/ml). This exogenous testosterone helps restore physiological levels, alleviating symptoms and supporting overall well-being.

To maintain natural testosterone production and fertility, Gonadorelin is often included, administered via subcutaneous injections twice weekly. This peptide stimulates the pituitary gland to release luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which are essential for testicular function.

Additionally, Anastrozole, an oral tablet taken twice weekly, may be prescribed to block the conversion of testosterone to estrogen, mitigating potential side effects like gynecomastia. In some cases, Enclomiphene may be added to further support LH and FSH levels, particularly for fertility preservation.

Testosterone Replacement Therapy Women

Women, including those who are pre-menopausal, peri-menopausal, or post-menopausal, can also experience symptoms related to low testosterone, such as low libido, persistent fatigue, and mood changes. Protocols for women typically involve lower doses of Testosterone Cypionate, often 10 ∞ 20 units (0.1 ∞ 0.2ml) weekly via subcutaneous injection.

Progesterone is prescribed based on menopausal status, playing a critical role in balancing estrogen and supporting uterine health. For some women, Pellet Therapy, which involves long-acting testosterone pellets inserted subcutaneously, offers a convenient and consistent delivery method. Anastrozole may be considered when appropriate, particularly if estrogen levels become elevated. These tailored approaches aim to restore hormonal equilibrium, addressing symptoms and enhancing quality of life.

Post-TRT or Fertility-Stimulating Protocol Men

For men who have discontinued TRT or are actively trying to conceive, a specific protocol is implemented to stimulate endogenous testosterone production and support fertility. This protocol typically includes Gonadorelin to stimulate pituitary function, along with selective estrogen receptor modulators (SERMs) such as Tamoxifen and Clomid. These medications help to block estrogen’s negative feedback on the pituitary, thereby increasing LH and FSH release and stimulating testicular testosterone production. Anastrozole may be optionally included to manage estrogen levels during this phase.

Growth Hormone Peptide Therapy

Beyond traditional hormone replacement, peptide therapies offer another avenue for supporting metabolic function and overall vitality, particularly for active adults and athletes seeking anti-aging benefits, muscle gain, fat loss, and improved sleep. These peptides work by stimulating the body’s natural production of growth hormone (GH) or by mimicking its actions.

Key peptides in this category include ∞

  • Sermorelin ∞ A growth hormone-releasing hormone (GHRH) analog that stimulates the pituitary gland to produce and secrete GH.
  • Ipamorelin / CJC-1295 ∞ A combination often used to provide a sustained release of GHRH (CJC-1295) and a selective GH secretagogue (Ipamorelin), leading to a more physiological pulsatile release of GH.
  • Tesamorelin ∞ A GHRH analog specifically approved for reducing visceral adipose tissue in certain conditions, also showing benefits for body composition.
  • Hexarelin ∞ Another GH secretagogue that can stimulate GH release, often used for its potential to improve cardiac function and muscle growth.
  • MK-677 (Ibutamoren) ∞ An oral GH secretagogue that increases GH and IGF-1 levels by mimicking ghrelin’s action, promoting muscle mass and reducing fat.

Other Targeted Peptides

Additional peptides address specific aspects of health that can be impacted by long-term metabolic and endocrine imbalances ∞

  • PT-141 (Bremelanotide) ∞ This peptide acts on melanocortin receptors in the brain to improve sexual function in both men and women, addressing issues like low libido that can arise from hormonal dysregulation.
  • Pentadeca Arginate (PDA) ∞ This peptide is utilized for its potential in tissue repair, accelerating healing processes, and reducing inflammation, which is particularly relevant given the chronic inflammatory state often induced by imbalanced dietary fats.

These protocols, whether hormonal optimization or peptide therapies, represent sophisticated tools for restoring balance when the body’s intrinsic regulatory mechanisms have been overwhelmed by persistent dietary and environmental stressors. They are not isolated treatments but components of a comprehensive strategy aimed at supporting the body’s inherent capacity for self-regulation and resilience.

Comparison of Dietary Fat Types and Their Endocrine Impact

Saturated Fatty Acids (SFAs) Red meat, butter, cheese, coconut oil Worsens insulin resistance, promotes inflammation, contributes to leptin resistance, alters cell membrane fluidity.
Trans Fatty Acids Processed foods, fried foods, some baked goods Strongly pro-inflammatory, increases oxidative stress, severely impairs cellular function and hormone signaling.
Monounsaturated Fatty Acids (MUFAs) Olive oil, avocados, nuts Improves insulin sensitivity, supports cell membrane integrity, generally anti-inflammatory.
Omega-3 Polyunsaturated Fatty Acids (PUFAs) Fatty fish (salmon, mackerel), flaxseeds, walnuts Anti-inflammatory, supports cell membrane fluidity, aids in hormone receptor function, may improve insulin sensitivity.
Omega-6 Polyunsaturated Fatty Acids (PUFAs) Vegetable oils (corn, soybean, sunflower), processed foods Excessive intake promotes pro-inflammatory eicosanoid production, contributes to chronic inflammation if unbalanced with omega-3s.


Academic

The long-term consequences of imbalanced dietary fat intake on endocrine system resilience extend into the intricate molecular and cellular landscapes of human physiology. This academic exploration moves beyond the symptomatic and clinical, delving into the precise biochemical pathways and systems-level interactions that underpin these profound effects.

The body’s endocrine network, a marvel of biological engineering, relies on precise molecular communication; when the very components of these messages are distorted by dietary fat quality, the entire system can experience a cascade of dysregulation.

Molecular Mechanisms of Insulin Resistance

At the heart of many endocrine disruptions caused by imbalanced dietary fats lies the molecular pathology of insulin resistance. While the intermediate section touched upon cellular insensitivity, a deeper look reveals the specific intracellular signaling pathways affected.

High intake of saturated fatty acids (SFAs) and trans fatty acids leads to the accumulation of specific lipid metabolites, such as diacylglycerols (DAGs) and ceramides, within non-adipose tissues like skeletal muscle and the liver. These lipid intermediates act as intracellular signals that interfere with the insulin signaling cascade.

Specifically, DAGs can activate novel protein kinase C (PKC) isoforms, particularly PKCθ in muscle and PKCε in the liver. Activated PKC isoforms then phosphorylate key components of the insulin signaling pathway, such as insulin receptor substrate-1 (IRS-1), at serine residues rather than tyrosine residues.

This serine phosphorylation inhibits the downstream propagation of the insulin signal, effectively creating a molecular “blockade” that prevents glucose transporter 4 (GLUT4) translocation to the cell membrane in muscle and suppresses hepatic glucose production in the liver. The result is a diminished cellular response to insulin, leading to hyperglycemia and compensatory hyperinsulinemia.

Mitochondrial Dysfunction and Oxidative Stress

Imbalanced dietary fats, particularly SFAs, also contribute to mitochondrial dysfunction. Mitochondria, the cellular powerhouses, are responsible for fatty acid oxidation and ATP production. Excessive lipid overload, driven by high-fat diets, can overwhelm mitochondrial capacity, leading to incomplete fatty acid oxidation and increased production of reactive oxygen species (ROS). This heightened oxidative stress damages mitochondrial DNA, proteins, and lipids, further impairing mitochondrial function.

Dysfunctional mitochondria are less efficient at energy production and contribute to a pro-inflammatory state. The accumulation of ROS can activate stress-sensitive kinases, such as c-Jun N-terminal kinase (JNK) and inhibitor of kappa B kinase (IKK), which in turn activate inflammatory transcription factors like Nuclear Factor-kappa B (NF-κB).

NF-κB activation promotes the transcription of pro-inflammatory cytokines (e.g. TNF-α, IL-6), creating a self-perpetuating cycle of inflammation that directly impairs insulin signaling and contributes to systemic endocrine dysregulation.

Imbalanced dietary fats disrupt cellular energy production and trigger inflammatory pathways, fundamentally altering hormone signaling.

Adipokine Dysregulation and Systemic Inflammation

The role of adipose tissue as an endocrine organ becomes even more critical at the academic level of understanding. In states of chronic positive energy balance and imbalanced fat intake, adipocytes undergo hypertrophy (increase in size) and hyperplasia (increase in number). This expansion, particularly of visceral adipose tissue, leads to a shift in adipokine secretion.

There is a decrease in beneficial adipokines like adiponectin, which normally enhances insulin sensitivity and possesses anti-inflammatory properties. Simultaneously, there is an increase in pro-inflammatory adipokines such as leptin (leading to leptin resistance), resistin, TNF-α, and IL-6.

This altered adipokine profile creates a state of chronic low-grade systemic inflammation. These inflammatory mediators circulate throughout the body, affecting distant organs and endocrine glands. For example, TNF-α can directly inhibit insulin signaling by inducing serine phosphorylation of IRS-1, mirroring the effects of DAGs and ceramides.

IL-6 can impair hepatic insulin sensitivity and contribute to the acute phase response. This inflammatory milieu directly impacts the function of the pancreas, liver, muscle, and other endocrine glands, reducing their responsiveness and resilience.

Gut Microbiota and Endocrine Crosstalk

A rapidly expanding area of research highlights the profound influence of the gut microbiota on endocrine health, particularly as mediated by dietary fat. Imbalanced dietary fat intake, especially high saturated fat diets, can induce gut dysbiosis ∞ an alteration in the composition and function of the gut microbial community. This dysbiosis can lead to increased intestinal permeability, often referred to as “leaky gut.”

When the intestinal barrier is compromised, bacterial components, such as lipopolysaccharides (LPS), can translocate from the gut lumen into the systemic circulation. This phenomenon, known as metabolic endotoxemia, triggers a robust inflammatory response. LPS activates Toll-like receptor 4 (TLR4) on immune cells and other tissues, leading to the activation of NF-κB and the subsequent release of pro-inflammatory cytokines.

This systemic inflammation directly contributes to insulin resistance, metabolic dysfunction, and can impact the HPA axis, influencing cortisol regulation. The gut-brain axis, a bidirectional communication pathway, is also affected, influencing appetite regulation and mood, which are intimately linked to hormonal balance.

Epigenetic Modifications and Long-Term Programming

Beyond immediate biochemical effects, long-term imbalanced dietary fat intake can induce epigenetic modifications, which are heritable changes in gene expression that do not involve alterations to the underlying DNA sequence. These modifications, such as DNA methylation and histone modifications, can alter the accessibility of genes involved in hormone synthesis, receptor expression, and metabolic regulation.

For example, a maternal high-fat diet during pregnancy can epigenetically program offspring for increased susceptibility to insulin resistance and metabolic dysfunction later in life, particularly affecting male offspring. This highlights how dietary fat choices can have intergenerational consequences for endocrine resilience, influencing the “set point” of metabolic health from early development.

These epigenetic changes can affect the expression of genes encoding for insulin receptors, adipokines, and enzymes involved in fatty acid metabolism, thereby predisposing individuals to long-term endocrine vulnerabilities.

Impact on Hypothalamic-Pituitary Axes

The three major hypothalamic-pituitary axes ∞ HPA (adrenal), HPT (thyroid), and HPG (gonadal) ∞ are exquisitely sensitive to metabolic signals and inflammatory states induced by dietary fat imbalances.

  1. Hypothalamic-Pituitary-Adrenal (HPA) AxisChronic inflammation and insulin resistance, driven by imbalanced fats, can dysregulate the HPA axis, leading to altered cortisol secretion patterns. While some studies suggest high sodium intake (often associated with Western diets) can increase cortisol, a Mediterranean-style diet can reduce it.

    Chronic cortisol elevation can further exacerbate insulin resistance and contribute to visceral adiposity, creating a feedback loop that diminishes adrenal resilience.

  2. Hypothalamic-Pituitary-Thyroid (HPT) Axis ∞ Thyroid hormone secretion can be influenced by nutritional signals like leptin. Leptin resistance, a consequence of imbalanced fat intake, may indirectly affect thyroid hormone levels and sensitivity, though the precise regulatory relationship is still under investigation.

    Thyroid hormones are crucial for metabolic rate and energy balance, and their dysregulation can lead to widespread systemic effects.

  3. Hypothalamic-Pituitary-Gonadal (HPG) Axis ∞ As discussed, the HPG axis is highly vulnerable. Chronic inflammation, insulin resistance, and altered adipokine profiles from imbalanced fats can directly impair gonadal function.

    In men, this can lead to reduced testosterone production and impaired sperm quality. In women, it contributes to conditions like PCOS and can disrupt menstrual regularity and fertility. The altered metabolic environment impacts the pulsatile release of GnRH from the hypothalamus and the responsiveness of the pituitary and gonads.

Longevity and Cellular Senescence

The long-term effects of imbalanced dietary fat intake extend to the very processes of aging and cellular longevity. Chronic inflammation, oxidative stress, and metabolic dysfunction induced by unhealthy fats accelerate cellular senescence ∞ a state where cells stop dividing but remain metabolically active, secreting pro-inflammatory molecules. These “senescent cells” contribute to tissue dysfunction and the development of age-related diseases.

The impact on endocrine resilience is clear ∞ a system constantly battling inflammation and oxidative damage ages prematurely, losing its capacity for robust self-regulation. Strategies that promote healthy fat intake, such as those rich in omega-3 PUFAs, are recognized for their “anti-aging” effects, supporting cognitive processes and maintaining synaptic functions. Conversely, diets high in saturated fats negatively impact brain functions and increase the risk of cardiovascular and neurological diseases, all of which have endocrine components.

Molecular Pathways Affected by Imbalanced Dietary Fats
Pathway/Mechanism Key Molecules/Processes Affected Endocrine Consequence
Insulin Signaling Cascade IRS-1 serine phosphorylation, PKC activation, GLUT4 translocation, hepatic glucose production Insulin resistance, hyperinsulinemia, increased risk of Type 2 Diabetes.
Mitochondrial Function ROS production, ATP synthesis, fatty acid oxidation, mitochondrial DNA integrity Oxidative stress, reduced energy efficiency, impaired endocrine gland function.
Adipokine Secretion Profile Decreased adiponectin, increased leptin, resistin, TNF-α, IL-6 Systemic inflammation, leptin resistance, exacerbated insulin resistance.
Gut Barrier Integrity Increased intestinal permeability, LPS translocation, TLR4 activation Metabolic endotoxemia, systemic inflammation, HPA axis dysregulation.
Epigenetic Regulation DNA methylation, histone modifications of metabolic/hormone genes Long-term programming of metabolic dysfunction, intergenerational vulnerability.
