At last check, my HDL was 77, which is pretty high for a guy. How did I get this? Not from exercise in particular, but diet. Five years ago, my HDL was around 50. What is my diet like? High in fats, but they are natural fats like those found in meat, fish, eggs, dairy, and nuts. I limit my intake of carbohydrates, refined carbohydrates in particular, but I do eat lots of fresh and frozen vegetables and limited amounts of fruit. I avoid highly processed fats like partially hydrogenated vegetable oil (this is a must to get that HDL up) and most liquid vegetable oils (extra virgin olive oil being an exception). It is hard to avoid soybean oil because it is in virtually everything like salad dressings and such. I also take a tablespoon of Carlson's Cod Liver oil every day for its high quality Omega 3 essential fatty acids EPA and DHA (and it is high in Vitamin A and D also).
Still not conviced that increasing your fat intake can raise your HDL? Read this:
STUDY REVEALS NO BENEFIT TO SELECTED CARDIOVASCULAR RISK FACTORS IN LOW-FAT DIET
For decades, low-fat diets have been advocated for weight reduction and to lower the risks associated with heart disease. However, clinical trials have not confirmed that low-fat diets actually accomplish this. In a study recently published in the Journal of the American College of Nutrition, Kulwara Meksawan, PhD, et al., studied the effects of dietary fat on selected cardiovascular risk factors of healthy, yet sedentary, men and women. Over a three-week period, researchers gathered data on 11 volunteers who followed a three-phase nutritional approach. The first phase allowed subjects to consume only 19 percent of their calories from fat, and the second phase, which was used as a control, allowed 30 percent of daily calories from fat. The final phase of the study increased calories from fat to 50 percent. Researchers found no adverse effects on body weight, body fat, blood pressure, resting heart rate or cholesterol levels in their study subjects. In fact, high-density lipoprotein (HDL) or "good" cholesterol levels improved on the diet that derived 50 percent of calories-from-fat.
In conclusion, researchers note that their data suggests a diet severely restricting dietary fat is not necessarily beneficial to the nutritional status and plasma lipoproteins of healthy sedentary people. Regardless of weight loss, very low-fat and high-carbohydrate diets did not show improved serum cholesterol, and since long-term compliance with such diets is poor,they do not result in long-term loss of weight or body fat.
