I am convinced by the overwhelming peer-reviewed research that anyone who eats a low-carb diet is increasing the risk of health issues such as heart problems. Importantly research shows it doesn't matter how much exercise or what exercise these people do makes absolutely no difference to that increased risk.
I post on this because of Bob Harper, a TV supposed diet and exercise guru who advocates a low-carb high-meat diet. Sadly for him he suffered a heart attack earlier this year. Fortunately although being, in his words, dead for two days, he did not actually die and is now recovering. This youtube video takes the instance of Bob Harper's dietary approach to task.
Bob now argues that he has some form of genetic predisposition to heart attacks. I think we all have such a predisposition: just eat enough fat. However that's not the end of the matter. There are rumours that Bob has now become a vegetarian. Perhaps soon he will improve his diet even more!
