Not if you read the research, the arguments are pretty compelling against carbohydrates unless you are running or something.
It also explains why so many people have stories that go something like, "Back in my day, we ate 5 eggs and 8 rashers of bacon for breakfast, on toast smothered in high fat butter, and we were fine." They actually were fine.
I think even the correlation between high fat diets and heart problems is not as strong as people believed. As far as I know (and I could be wrong) obesity itself is correlated more strongly with heart disease than high fat diets. In other words, if you get fat from carbs but dont eat fat, you are still in trouble. Conversely, if you eat a lot of fat but stay thin, you're not at zero risk but are better off than the fat dude who only eats white bread and coke.
It actually doesn't matter what you eat: proteins, lipids, carbohydrates. They're all basically hydrocarbon skeletons with some amine groups in some cases. They can each be converted to one another depending upon the needs of your body. Regardless of which one you eat if you sit on your ass and do nothing after eating them they will become "fat" and be stored.
