What is Metabolic Health — and Why It Matters

Metabolic health is about how well your body generates and uses energy. At the heart of this process are your mitochondria - the little power plants inside your cells that convert nutrients into energy and keep everything running. If functioning properly, mitochondria help fuel everything from brain function to physical activity. When your diet is high in sugar, refined carbohydrates, and ultra-processed foods, your blood sugar and insulin levels can stay too high for too long. The “standard American diet” promotes chronic inflammation that over time overloads and damages the mitochondria, leading to insulin resistance. Meaning eventually your body becomes less responsive to insulin, making it harder to keep blood glucose in check. This sets the stage for fatigue, weight gain, hormonal imbalances, and increased risk of health concerns. Data from 2023 estimates that at least 88% of Americans are metabolically unfit, with one or more chronic conditions that affect their quality of life.

Mitochondria are deeply connected to almost every system in your body. When they are working well, you feel focused, energized, and resilient. But when your mitochondria become damaged or dysfunctional, it can have ripple effects far beyond just feeling tired. Mitochondrial dysfunction and insulin resistance are at the root of conditions like type 2 diabetes, heart disease, stroke, fatty liver disease, polycystic ovarian syndrome, some cancers, and more. Many autoimmune conditions and inflammatory disorders show signs of impaired mitochondrial health.

Emerging research shows a strong link between mitochondrial dysfunction and mental health and psychiatric conditions including depression, anxiety, ADHD, and Bipolar disorder. Why? Because your brain is one of the most energy-hungry organs in your body. When mitochondria can’t produce energy efficiently, brain function suffers, and can lead to mood issues, brain fog, and emotional dysregulation.
