This study is looking at how a high-fiber diet, high-intensity interval exercise, or a combination of both can improve health for people with Heart Failure with Preserved Ejection Fraction (HFpEF). HFpEF is a type of heart failure where your heart can pump blood normally, but it's too stiff to fill properly. You might be able to join if you are at least 40 years old, have HFpEF with NYHA class II-III symptoms (meaning you have some limitations with physical activity), have doctor's approval for exercise and diet, and are fully vaccinated for COVID-19. The study will measure success by looking at your VO2peak (a measure of how well your body uses oxygen during exercise) after 4 weeks. The current recruitment status is unclear.
