My boyfriend had exactly the same problem last November. His doctor wanted to wait a month before putting him on meds to see if he can lose some weight and exercise, and see if that would have an impact on his cholesterol/triglyceride numbers. His numbers were off the charts high, and the "good" cholesterol was very low.
Right away, my boyfriend increased his fiber intake, eating high fiber, low sugar cereals like three times a day. He ate more fruits and veg's, drank tons of water, and decreased his fat and dairy in take. He did this EVERY DAY for a month. In addition to this, he started taking garlic, green tea, and chromium picolinate supplements (his doc told him to try the picolinate, but I've just read it may not be good to use). Also he tried Xtendlife Cholest-Natural - a supplement we found on the internet. (We are not the types to just get stuff from the internet and trust it right away, I guess the Xtend life was an exception.)
Anyway, within in a month and a half's time, he had lost 13 lbs and his number went down to normal. His doctor was very truly amazed, as were we! We can't pinpoint what exactly worked, if it was the weight loss or the supplements or both, but something did work!
