Unhealthy lifestyle choices, particularly a diet high in saturated and trans fats, are major contributors to increased LDL cholesterol levels. Consuming foods like fatty meats, full-fat dairy products, fried foods, and processed snacks can raise LDL cholesterol. Lack of physical activity, obesity, smoking, and certain medical conditions like diabetes and kidney disease also play a role in increasing LDL cholesterol. While genetics and family history can influence cholesterol levels, lifestyle factors are the primary drivers of LDL cholesterol increase. By adopting a heart-healthy diet, engaging in regular exercise, maintaining a healthy weight, and other lifestyle modifications, you can effectively reduce LDL cholesterol levels. In some cases, medication may be necessary, as prescribed by a healthcare professional.
