Saying that something is genetic does not mean that it isn't diet related. The food we eat can turn genes on and off. Some people may have a greater genetic propensity to develop heart disease (or any other disease) but whether that propensity is realized will depend on the environmental influences that effect them which includes diet. That said anything any of us would say about the cause of Bob Harper's heart attack would only be speculation. That he is a cast member of that fat shaming show is another issue entirely. I hope he recovers his health and makes wise decisions for himself going forward.
