Overview

Metabolism is how the body converts food into energy and manages fuel — glucose, insulin, and lipids. Metabolic health underlies cardiovascular disease, diabetes, liver disease, and more.

Why it matters

Insulin resistance and metabolic dysfunction are upstream of many chronic diseases. Because they develop silently over years, early markers and lifestyle change offer a large window to intervene.

Frequently asked questions

How do I know if I'm metabolically healthy?

No single number tells the whole story — clinicians look at glucose, insulin, triglycerides, blood pressure, waist size, and liver enzymes together.

Are GLP-1 medications a shortcut?

They produce substantial, proven weight loss and metabolic benefit, but they're chronic therapies with side effects and cost — best understood as one powerful tool, not a replacement for the fundamentals.
