It has been understood for a long time that obesity has a direct impact on lipid metabolism and there is a close correlation between BMI, high levels of LDL cholesterol and reduced levels of HDL cholesterol. There is an increased intimate relationship between obesity and increased cholesterol, both linked with increased consumption of saturated and trans fats, abundant in many foods, even those that seem not contain them.
People with central or truncal obesity, which is predominantly distributed the extra weight around the body and upper abdomen, are particularly susceptible to hypercholesterolemia. This pattern of distribution of fat is associated with increased levels of visceral fat, believing that it is more metabolically active than the predominant subcutaneous fat in non-stem fat patterns distribution.
Obesity is also a risk factor for diseases such as diabetes (because it generates changes of lipid metabolism and negatively impacts the glucose-insulin) and hypertension, which in turn are associated with increased risk of atherosclerosis and high cholesterol. Many obese people are known by a sedentary lifestyle, and may find it particularly difficult to practice regular exercise, increasing their risk of developing hypercholesterolemia.
When truncal obesity, high cholesterol, high blood glucose and / or hypertension occur at the same time, you can make a diagnosis of metabolic syndrome or X syndrome. Individuals with X syndrome have an increased risk of developing several serious diseases such as diabetes, cardiovascular disease, stroke and some cancers.
Changes in diet and lifestyle are very important in the prevention and management of obesity and high cholesterol levels. In addition to practicing regular exercise (find the best exercises for weight loss here) and quitting smoking, some dietary changes such as reducing trans and saturated fats, eat a moderate amount of saturated fat and increasing intake of soluble fiber can be all that is needed to restore and maintain healthy weight and normal levels of cholesterol. However, if these changes have no significant impact after several months, then medication for lowering cholesterol may be prescribed.
