No, cholesterol doesn't drop quickly with diet alone—expect modest changes in 3-6 weeks for LDL/triglycerides, with full effects in 3-6 months.
Realistic Timeline
Diet tweaks (cut saturated fats <7% calories, add soluble fiber 10-25g/day from oats/beans, omega-3s from fish) lower LDL 5-15% initially, stabilizing after 12 weeks. Add exercise/statins for faster drops (20-30% in 4-6 weeks).
Triglycerides fall quicker (14-42% in 3-12 weeks with intermittent fasting or low-carb).
Why Not Instant
Liver produces 75% cholesterol; diet impacts the rest via absorption. Genetics matter—some see 10% drop in 3 weeks, others slower. Retest at 3 months; consistency beats speed.
