The non-pharmacological (other than drugs) ways to reduce cholesterol
1. Decrease intake of saturated fats and excess of carbohydrates.
2. Maintain ideal body weight.
3. Exercise daily for ~45 minutes after consulting your doctor.
4. Intake of appropriate calories as per your weight, height , life style and gender.
in future, not only depends upon your cholesterol levels but also on many other factors like presence of cardio-vascular disorder/ diabetes/ kidney
disease etc. but , yes theoretically it is feasible to stop statins in future.
