6 Changes in Your Blood After 90 Days of Fasting (Science Explained)

6 Changes in Your Blood After 90 Days of Fasting (Science Explained) This video explains the six blood test changes that occur after 90 days of intermittent fasting, from insulin to liver enzymes. Blood work reveals what the scale and mirror cannot, showing measurable shifts in metabolic and cardiovascular markers over three months. The video reads through each marker, what it means, and the honest research behind how much it changes. What's covered in this video: How fasting insulin and HOMA-IR drop, the marker most profoundly changed in fasting studies, reversing insulin resistance. Why HbA1c, the three-month blood sugar average, makes 90 days the ideal window to prove real metabolic change. How triglycerides fall while HDL cholesterol often holds or rises, with an honest note on variable LDL. Why the inflammation marker CRP tends to cool, lowering heart disease and stroke risk. How blood pressure eases as insulin drops and the kidneys release retained salt and water. Why liver enzymes ALT and AST fall as fasting drains fat from a fatty liver. Mentioned in this video: intermittent fasting, fasting insulin, HOMA-IR, insulin resistance, HbA1c, prediabetes, triglycerides, HDL, LDL, CRP, C-reactive protein, blood pressure, ALT, AST, fatty liver disease, NAFLD.
