The Claim

In older obese adults with heart failure with preserved ejection fraction, caloric restriction combined with aerobic exercise improves quality of life as measured by the Kansas City Cardiomyopathy Questionnaire by approximately 17–23 points over 20 weeks, and adding resistance training does not further improve this outcome.

In plain English

In older adults who are obese and have heart failure with preserved ejection fraction, a program of reduced calorie intake and aerobic exercise increases quality of life scores on the Kansas City Cardiomyopathy Questionnaire by 17 to 23 points after 20 weeks, and adding resistance training provides no additional benefit.

Why this might work

Losing excess body fat and doing regular cardio lowers pressure in the blood vessels and reduces stiffness in the arteries, which makes it easier for the heart to fill with blood between beats. This reduces chest tightness and fatigue, helping people feel better in their daily lives.

  1. Study: A Randomized, Controlled Trial of Resistance Training Added to Caloric Restriction Plus Aerobic Exercise Training in Obese Heart Failure with Preserved Ejection Fraction

    In older obese adults with a type of heart failure, eating less and doing cardio made them feel much better in their daily lives—by about 17 to 23 points on a quality-of-life scale. Adding weight training made their legs stronger but didn’t make them feel any better than just dieting and cardio alone.
