Tim originally experimented with policosanol at both high and low doses to in an effort to increase HDL (good) cholesterol and decrease LDL (bad) cholesterol. Remarkably, Ferriss was able to lower his total cholesterol from 222 to 147 while almost doubling his HDL cholesterol when taking policosanol before bed. Along with improving his cholesterol levels, Ferriss noticed an unintended reduction in body fat. After more testing and experimenting with different dosages, Ferriss concluded that 23 milligrams of policosanol before bed was optimal for fat-loss. Ferriss specifically takes Nature’s Life Policosanol.
