After his February 2017 heart attack, fitness trainer Bob Harper said he changed how he ate: he moved toward Mediterranean-style meals, gave up red meat, and ate more fish and plant-based protein. In a later interview, he described a more balanced mix of protein, carbohydrates and fat, with a low-fat lean. These are descriptions of his own choices over time—not a single, formal diet plan or advice for every heart patient.
What Harper said he changed
Harper’s accounts point to a shift in both food choices and the way he thought about eating. In 2018, AARP reported that he had given up red meat and was eating more plant-based proteins and fish. Men’s Health that year described his approach as Mediterranean-style and noted that he was eating more vegetables.
- Less red meat: AARP reported that Harper had given it up.
- More fish and plant-based protein: These were among the foods he said he was eating more often.
- A Mediterranean-style pattern: Men’s Health used this description of his post-heart-attack eating.
The reports describe broad choices, not a detailed menu, serving sizes or a set of rules to follow.
How his later description differed
In a 2021 Parade interview, Harper framed his diet in terms of macronutrients: “My diet is much more balanced now, utilizing all the macronutrients (protein, carbs and fat).” He also described leaning toward a low-fat pattern.

That emphasis is not necessarily at odds with the earlier accounts. The 2018 reports highlighted foods and an overall Mediterranean-style pattern; the later interview highlighted balance among protein, carbohydrates and fat. The sources do not establish one exact plan or say that the later description replaced the earlier one.
His heart attack and recovery matter to the story
Harper had a heart attack during a workout in February 2017. The American Heart Association reported that he later learned he had familial hypercholesterolemia, an inherited condition associated with elevated LDL cholesterol and increased cardiovascular risk. His fitness did not make him immune to a heart attack, and the available accounts do not establish that his diet caused the event.
Rank #2
In 2018, Harper told AARP, “I’m an ideal patient now; I’m doing exactly what my doctors tell me to do.” AARP also reported that his recovery involved medication and cardiac rehabilitation. He described rebuilding confidence in his heart as gradual: “It was a slow process of building my relationship and trust with my heart again.”
His story therefore involves more than changing food choices. Harper’s own accounts place his eating changes alongside medical care and rehabilitation; they do not present diet as a substitute for either.

What his story can—and cannot—tell you
Harper’s interviews are useful for understanding how he described adapting after a serious health event. They are not a prescription for other people recovering from heart disease. Food choices and treatment need to account for an individual’s health, medications and clinician’s advice. Anyone making changes after a heart attack should discuss them with their care team.
Men’s Health mentioned Harper’s book The Super Carb Diet in its 2018 coverage, but the reporting does not establish that the book describes his post-heart-attack eating plan. It should not be treated as a cardiac-health recommendation based on these interviews.
