How to change hdl and ldl levels?

Lipids: Low fat and low carbohydate diet with lots of aerobic exercise.

HF/LC ↓BodyFat &Meds: Low fat theory by ancel keys; long promoted; opposite evidence. ↓ & efficient body fat is healthy. Ldl & HDL are complex particles, 80-100 proteins/particle: transport all fat molecules in h20 outside cells. Each LDL particle carries thousands of cholesterol, triglyceride, phospholipid & other fat molecules. Cholesterol often misleading, get NMR particle test. Statins↓ldl niacin↑hdl, carbs↑ldl↓hdl.

Diet, exercise, meds: Hdl can improve through regular aerobic exercise. It also responds to nicotinic acid (niacin), as well as to statins, fibrtes, and fish oil. Ldl improves through weight loss, dietary modifications (less fat containing foods), and meds (statins, niacin, bile acid resins, and enteric binders like welchol (colesevelam) and zetia). Every pound lost in someone overweight typically drops LDL by 1-1.5 points.

Foods Meds Exercise: Hdl & LDL are complex protein particles which transport all fat molecules in the water outside cells. Get NMR particle test for accurate data. Carbs(sugar) & obesity raise LDL & especially ↓ large HDL levels. Thus go hf/lc foods. Statins & chol absorption inhibitors tend to ↓ LDL particle concentrations. Cutting carbs, Niacin & intense exercise usually ↑ hdl, esp large-hdl particle concentrations.
