Cholesterol, a waxy substance produced by the liver, circulates in the bloodstream to be used by cells. It also is eliminated by the liver. Excessive levels of cholesterol, however, can accumulate in arteries and restrict blood flow. Following a low cholesterol diet can lower blood levels of cholesterol and may help you lose weight.
Types of Cholesterol
Cholesterol moves through the bloodstream attached to proteins called lipoproteins, according to Diet.com. Low-density lipoproteins (LDL), also called "bad" cholesterol, pick up cholesterol in the liver and travel through the body. If too much cholesterol is present from overproduction by the liver or from a diet of high cholesterol foods, the cholesterol sticks to artery walls and forms plaque. As plaque accumulates inside arteries, the passages narrow and restrict blood flow. Plaque raises the risk of blood clots and may cause a stroke or heart attack if arteries of the brain or heart become blocked. High-density lipoproteins (HDL), sometimes referred to as "good" cholesterol, remove cholesterol from the arteries and return it to the liver, where it is eliminated.
Cholesterol and Weight Loss
Dietary cholesterol is found in meats and dairy products. Reducing the amount of dietary cholesterol reduces the overall levels circulating in the body, according to Diet Spotlight. The goal of low cholesterol diets is to lower LDL levels while increasing HDL levels. The focus is not weight loss; however, following a low cholesterol diet involves limiting high-fat foods and eating more fruits, vegetables and whole grains. By eating healthier to reduce cholesterol, many people find they lose weight in the process. Adding exercise to a low cholesterol diet increases the weight loss and cholesterol lowering benefits.
Foods to Avoid
Organ meats, such as liver, contain the highest amounts of cholesterol and should be avoided in a low cholesterol diet, according to Diet.com. Whole-milk dairy products and red meats with fat marbling are not recommended for a low cholesterol diet. Avoid saturated fats--for example, butter, shortening, lard and other meat fats.
Beneficial Foods
Eat fruits, vegetables and whole grains to lower LDL and raise HDL. Diet.com suggests choosing monounsaturated fats (for example, olive or canola oils) or polyunsaturated fats (such as corn, soybean or safflower oils). Use margarine rather than butter. Broil, roast, grill or bake food and ask for gravy, salad dressing and sauces on the side. Dietary fiber increases HDL levels, so include oatmeal and oat bran, brown rice and whole grain bread in your diet. Following a healthy, low cholesterol diet and controlling portions can lead to weight loss.
Cautions
A low cholesterol diet requires no special foods and is safe and healthy for anyone to follow, including children, according to Diet Spotlight. However, consult your doctor before beginning any diet. Following a low cholesterol diet may not reduce cholesterol to the desired levels, and you may require cholesterol-lowering medications. Remember, weight loss is not the goal of this diet, although you may shed pounds by eating healthier.
