16 biomarkers impacting weight gain and loss: Insulin Glucose Hemoglobin A1C (HbA1c) Thyroid Stimulating Hormone (TSH) Triiodothyronine (T3) Free Thyroxine (T4) Free Thyroglobulin Antibodies (TgAb) Thyroid Peroxidase Antibodies (TPO) Leptin Cortisol High-Sensitivity C-Reactive Protein (hs-CRP) Triglycerides Apolipoprotein B (ApoB) Vitamin D Magnesium Iron Many of these lab tests are often overlooked during routine check-ups, but advanced testing can expose these invisible issues. If you’re not s

Overeating isn’t about willpower—it's about biology. Leptin, a hormone produced by fat cells, signals fullness to the brain. When leptin is out of balance and leptin resistance develops, it sends false hunger signals, leading to overeating and slow metabolism. Testing leptin levels provides insight into this imbalance. To gauge the broader cardiovascular and metabolic risks linked to leptin resistance, combine leptin testing with: -Insulin -High-Sensitivity C-Reactive Protein (hs-CRP) -Apolipopr
