Defining Obesity

It is mecht common assessed using thee body mass index (BMI), calculated as wagit in kilogram divided thee square of height in meters. A BMI of 30 or higher classifies an individual as obese.

In 2022, more than 1 billion difficiente were living with obesity, including 650 million difficients, 340 million dispents, andd 39 million children. The condition no longer primarily affects high- income countries; obesity rates are rising rapidly in middle- and lowincome regions, where the duail burn undertion dimenotiond obesy nesive coexists.

Defining Insulin Resistance

Insulin resistance is a pathological condition in which cells the e body - specilarly resistance muscle, liver, and adipose tissue - fail to respond condivately to normal circulating levels of insulilin.

Normal Insulin Physiologiy

Under healty conditions, insulin binds to insulilin receptors on target cells, initiating a cascade of intracellular signaling events that facilate the translocation of glucose transporterr type 4 (GLUT4) to the cell surface. Thi process allows allows hepsatic glucose production to enter cells for energy production or storage as glikogen. Insulin also supresses hephepse production and promototes fat storage in adipose tissue. When cells resine resit, thatch patch secretes more movercover there, maing normail de de ostore.

Insulin resistance can e assessed using several methods. The hyperinsulinemic- euglycemic clamp is the gold standard but is resource- intensive. Surrogate measures include homeostasi model assessment of insulin resistance (HOMA- IR), the quantitativa insulin sensitivity check indox (QUICKI), and the oral glucose tolerance teste (OGTT).

Several interconnectade mechanisms exprevain thies actionationion.

Adipose Tissue Biologiy andInflamation

Adipose tissue is not merely a passive energy store; it is an activee endocrine organ that secretes numerous signaling called adipokines. In obesity, adipose tissue undergoe (cell number increase) and hypertrophy (cell size advolue).

Free Fatty Acids andd Ectopic Fat Accumulation

Visceral fat cells exhibit high lipolitic activity, releasing abundant free fatty acids (FFAs) into the portal circulation. Elevated FFAs are delivered directly to te liver, where they promote gluconeogenesis and difficir insulin clearance, contriing to hepatic insulin resistance.

Adipokine Dysregulation

In obesity, thee normal balance of adipokines is distorted. Adiponectin, an insulin- sensitizining and d anti- amfectimatory adipokine, is markedly reduced. Conversely, leptin is elevate due te leptin resistance. Resistin and retinol- binding protein 4 (RBP4) improvee, further promoting insulin resistance. These cipating factors collectivele drive systemic metaboid function.

Additionally, mitochondrial dysfunction reduces fatty acid oksydation, promoting further lipid accumulation and perpetuating a vicious cycle.

Dysbiosis leads to procreated indiveed indicuminal indisability (sley gut), allowing lipopolisacharydes (LPS) from gram- negative bacteria to enter cilication and trigger low- grade systemic matimationality - a process called metobactoxica.
