Weight Management & Obesity

Weight management challenges are rarely a simple matter of willpower or caloric math. The body's weight regulation system is governed by a complex interplay of hormones — including insulin, leptin, ghrelin, cortisol, thyroid hormones, and sex hormones — that influence hunger, satiety, fat storage, and metabolic rate. As we age, metabolic rate slows, muscle mass declines (reducing caloric burn), and hormonal changes shift the body toward fat storage, particularly in the abdomen. Insulin resistance — in which cells become less responsive to insulin's signal to absorb glucose — is a common underlying driver of weight gain that is often undiagnosed.

Weight management difficulty presents as an inability to lose weight despite consistent effort, or a gradual, unexplained weight gain over months or years. The weight often accumulates preferentially in the midsection (visceral fat), which carries greater metabolic health risks than subcutaneous fat. Patients may notice that strategies that previously worked — cutting calories, increasing exercise — are no longer effective. Intense food cravings, particularly for carbohydrates and sweets, are common and reflect underlying hormonal dysregulation. Fatigue, poor sleep, and mood changes often accompany weight struggles, creating a cycle that makes behavior change more difficult.
