Overweight or obese is one of the negative factors causing high cholesterol. Most people having misconception that only fatty need to concern about dietary issue, chronic disease such as heart attack, high cholesterol, diabetes will not happen to lean people, and in reality we often see a lot of fatty having high cholesterol. BUT, lean people should not take for granted that high cholesterol only happen to fat people. High cholesterol may cause by genetic and lifestyle.
Diabetes, kidney disease, thyroid dysfunction and other disease may also cause high level of cholesterol. Familial hypercholesterolemia (FH) is an autosomal dominant disorder. Those patients not necessary are fat, some even very skinny but cholesterol level is high. Poor dietary habits, including eating too much high fat, greasy food and unhealthy habits, such as staying up late, lazy to move, etc., more and more lean people also joined the ranks of high cholesterol.
Nowadays, there are many young people over the intake of high fat, high calorie, high-cholesterol foods, do not eat fruits and vegetables, network addicted, pay no attention to sports, these are bad habits, even lean or skinny, cholesterol might also be "excessive." Therefore, regular medical examination is necessary, if high levels of cholesterol is found, should be treated.
In addition, a British study shows that lean people who do not exercise regularly may have the same level of cholesterol compare to fatty.
The London-based team measured the levels of heart-clogging cholesterol (LDL) in 110 peoples which divided into 3 groups, 36 lean exercisers who took regular cardiovascular exercise, such as running or cycling, three times a week or more, 46 lean non-exercisers and 28 obese non-exercisers.
They found lean exercisers had good LDL levels, but those in lean and obese non-exercisers were higher and similar. And, lean exercisers have lower risk of cardiovascular disease, the aerobic energy higher than 30% of those who do not exercise. Dr Gary O'Donovan, exercise physiologist at Brunel University, said: "It was already known that aerobic fitness was amongst the most reliable measure of health now and in the future and that those who did well in fitness tests were likely to live around five years longer".
This study also showed that lean non-exercisers' body fat may not higher than those fat people but the cholesterol in blood may be the same, the risk of heart disease and other diseases might also same with those who are fat. This is because the heart has nothing to do with fat, and cholesterol levels are closely linked.
Peng Yuqing, associate chief physician of Beijing University of Chinese Medicine subsidiary Dongfang Hospital pointed that blood cholesterol has nothing to do with the subcutaneous fat, those with normal metabolism who have slim body if do not control on dietary and healthy lifestyle, may have risk of having high cholesterol. Peng Yuqing stress on intake of animal offal, especially liver which has high cholesterol content, and seafood such as squid, shrimp, crab roe are high-cholesterol food, do not take too much each time, especially for elderly. Besides that, mental stress, tension and staying up late, excessive stress causing the body tends to appear lipid metabolism and may also lead to high cholesterol.
Therefore, lean people should also develop awareness of fitness and practise good exercise habits. As long as you have the sense of fitness, beside running, swimming and other sports activities, you may also climb up stairs and mop the floor any day anytime in your lifetime, these are also good form of exercise.
体重超重是高胆固醇的一个不利因素。大部分人都认为，减肥只是胖人的事，而像心脏病、高血脂、糖尿病这些富贵病更不会找上瘦人，在日常生活中，我们也经常看到很多胖人胆固醇高。然而，瘦人不要认为高胆固醇是胖人的『专利』而掉以轻心，先天的遗传与后天的生活习惯是造成胆固醇偏高的主要原因。
糖尿病、肾病、甲状腺功能减退等病患都有可能造成胆固醇偏高，『家族性高胆固醇症』是种发生在常染色体上的显性遗传病，患者虽然不胖，有的甚至非常瘦，但是胆固醇却很高。受不良的膳食习惯，包括食用过多高脂肪、油腻食物与不健康的生活习惯，如熬夜、懒动等，愈来愈多的瘦人也加入到高胆固醇的行列。
如今许多年轻人过度摄入高脂肪、高热量、高胆固醇食物，不爱吃水果和蔬菜，贪恋网络，不注意运动，有这些不良的习惯，就算是瘦人，胆固醇也会『超标』。因此定期到医疗机构检查是很必要的，万一发现胆固醇偏高要及时治疗。
另外，英国的一项研究显示，瘦人不经常运动，胆固醇和胖人一样高。
在这项研究中，研究人员将110名男性分为3组：36人体型偏瘦，每周做3次有氧运动，如跑步、骑车等;46人同样体型偏瘦，但不运动; 另外28人为没有运动习惯的肥胖者。
研究最后显示，虽然两组瘦人的体重和身高相差不多，但有运动习惯的人体内总胆固醇和低密度胆固醇含量明显低于不运动的人，患心血管疾病的风险最低，其有氧能量高于不运动者30%。英国布鲁内尔大学运动科学系教授加里·多诺万表示，有氧能量是最可靠的健康指标，在体能测试中有良好表现的人，会比其他人长寿约5年。
这项研究还指出，体型偏瘦，但没有运动习惯的人，虽然脂肪没有胖人多，但血液中的胆固醇含量却没有改变，心脏病等疾病的发病风险与胖人无异。因为心脏病与脂肪多少无关，而与胆固醇含量紧密相连。
北京中医药大学附属东方医院亚健康科主任彭玉清指出，由于血液中胆固醇含量与皮下脂肪含量无关，代谢正常的人即使是体型偏瘦的人若不注意饮食和生活习惯，同样有高胆固醇的风险。彭玉清强调，动物内脏，尤其是肝脏的胆固醇含量最高，海鲜中的鱿鱼、虾米、鱼子和螃蟹都是高胆固醇的食物，每次不可多吃，尤其是老人。而长期精神紧张、压力过大和熬夜，过度应激，容易使机体出现脂代谢紊乱，同样是导致高胆固醇的诱因。
因此建议，体型较瘦的人也应该培养健身意识，养成良好的运动习惯。只要你有了健身意识，除了跑步、游泳等运动外，日常生活中随时随地都可以做的爬楼梯，拖地等，也是不错的锻炼方式。
