It's absolutely hard. I just expect that a blanket "carbs are evil" is likely to be as incorrect as the blanket "fats are evil" advice. (e.g., the Twinkie diet http://www.cnn.com/2010/HEALTH/11/08/twinkie.diet.professor/index.html http://www.cnn.com/2010/HEALTH/11/08/twinkie.diet.professor/... ) Amount of food we eat, roughly eetimatable as calories, is important. I think gut biota is also an interesting field we are just learning about. But yes, eat in moderation and exercise.
