Anytime you consume more calories than your body uses, no matter what type of food those calories come from, you will not lose weight or you will gain weight. This is why he said to not count calories but they do count and why he said that exercise is not optional. Eat the correct foods in the right porportions for your activity level or get up an move more and have more freedom in what you eat.

When you eat fat, the body is slower to break it down and get it into your bloodstream. So, you are fuller longer and more satisfied with what you eat. You have a steady stream of energy rather than the fast burst that carbs provide. Any fat you don't use is not just flushed magicly from the body it is stored, just the same, as anything else.
