Why test for weight loss?
If you're eating well and exercising but not losing weight, there may be a medical reason. Thyroid disorders, insulin resistance, hormonal imbalances, and chronic inflammation can all make weight loss significantly harder. Testing identifies these barriers so you can work with your body — not against it.
