Fat is much more difficult to metabolize. Sugar is easily assimilated into your body.

Best to give up the carbs then you'll be OK.

But fat still delivers more than twice the amount of calories per gram as carbs. Your body needs a lot of glucose to operate effectively. Carbs are an important part of any diet and, like all macronutrients, should be consumed in moderation. Trying to demonize one macronutrient over another doesn't make much sense because the problems being debated can normally be avoided by simply consuming less energy than you expend.

My grandfather's generation were mostly employed by agriculture. They worked like hell and consumed a diet high in carbohydrates. Yet obesity and diabetes were rare. Michael Phelps consumes around 12,000 calories a day when he's in training. His diet is heavily weighted to carbohydrates because he needs the energy. He needs his glycogen reserves maxed out. I'd say he's in pretty good shape and is one hell of a competitor. He wouldn't be either of those if he didn't "carb up" like he does.
