Does regular walking improve lipid levels in adults?

Q: Evidence-based answer: Minimally. Regular moderateintensity walking for a period of 4 or more weeks minimally decreased total cholesterol (TC) and low-density lipoprotein (LDL) levels by about 7 mg/dL in women with overweight or obesity (strength of recommendation [SOR]: C, systematic review and meta-analysis on disease-oriented evidence). For adults ages 40 to 65 years, regular walking for 3 or more months inconsistently affected cholesterol and triglyceride levels (SOR: C, based on 3 randomized controlled trials [RCTs] with disease-oriented evidence).Kayla Hatchell, MD; Emily Chin, DO; Brian Vukelic, MD; Katherine Fortenberry, PhD; Dominick Ose, DrPH; Eliza Taylor, MPH, BS, CHES; Rachel Goossen, MD (University of Utah), Rick Guthmann, MD, MPH (Advocate Health Care Illinois Masonic Medical Center Program)Includes bibliographical reference
