Weight Management + Thyroid


While diet and exercise play an important role, hormones can also have significant impact on weight management. Hormones are key players in regulating weight, metabolism, blood sugar, insulin, and when and where the body stores fat. 

The following hormone imbalances are key contributors to weight gain:

Oestrogen Dominance – oestrogen/progesterone imbalance leads to weight gain in hips, thighs; water retention; low thyroid/metabolism

Androgen Deficiency – testosterone/DHEA imbalance leads to decreased lean muscle, low metabolic rate, with increases in body fat and lowered metabolic rate

Vitamin D3 Deficiency – leads to hyperinsulinemia; visceral fat

Thyroid Deficiency – elevated TSH is indicative of hypothyroidism, low metabolic rate, stalled weight loss, obesity

Insulin Resistance – elevated fasting insulin indicates insulin resistance, a precursor of metabolic syndrome. Increased appetite, sugar cravings, belly fat; inhibits thyroid and metabolism; combined with elevated HbA1c is predictive of type 2 diabetes

An Ideal Screening Tool

Used as a screening tool, the ZRT Laboratory Weight Management Profile aids in early detection of insulin resistance, metabolic syndrome and type 2 diabetes.

The comprehensive test report is designed to help clinicians:

  • recommend effective treatments to rebalance hormone levels
  • address vitamin D and thyroid deficiencies
  • reduce overall risk for metabolic syndrome
  • potentially avoid the onset of type 2 diabetes
