Lifestyle changes recommended for those with high cholesterol include: smoking cessation, limiting alcohol consumption, increasing physical activity, and maintaining a healthy weight. A diet that emphasizes low-cholesterol foods, restricts saturated fats,[7] and avoids trans fat is also recommended.[34] In strictly controlled surroundings, dietary changes can reduce cholesterol levels by 15%. In practice, dietary advice can provide a modest decrease in cholesterol levels and may be sufficient in the treatment of mildly elevated cholesterol.[35]
