Find out why you’re having trouble losing weight
If only maintaining a healthy weight were as simple as the “calories in, calories out” formula. In truth, a number of genetic and biological factors can impact your weight—ranging from leptin resistance, which means you never feel full—to hormone imbalances. Once you understand why diet and exercise haven’t been sufficient to get you to your ideal weight range, you can modify your lifestyle and work with your doctor to develop a strategy to achieve your health goals.
Weight loss tests can help:
- Find out if an abnormal thyroid is making it harder to lose weight
- Learn whether hormone imbalances and elevated cortisol are contributing to your diet struggles
- See whether food allergies or intolerances are at play
- Test for leptin resistance, insulin resistance and more!
