How long does it take to lower cholesterol levels?

Cholesterol: It can take 6 to 8 weeks to see changes in cholesterol after changes in diet or starting a new medicine. We usually wait 2 or 3 months to recheck the fasting lipid panel in order to see any changes.

Varies: Cholesterol medications can affect your lipid panel within 4 weeks however dietary changes need time. You can not reverse years of eating poorly in two months. I see dietary shifts in cholesterol over 6 months and longer. Eating better is a lifestyle not a diet.
