How pasta ends up on your hips when too many carbs pass your lips

Your cells budget energy very carefully. They do not store more than they need right now. Any glucose the cell does not need for its daily work is converted to glycogen (animal starch) and tucked away as stored energy in your liver and muscles.
Your body can pack about 400 grams (14 ounces) of glycogen into liver and muscle cells. A gram of carbohydrates — including glucose — has four calories. If you add up all the glucose stored in glycogen to the small amount of glucose in your cells and blood, it equals about 1,800 calories of energy. If your diet provides more carbohydrates than you need to produce this amount of stored calories in the form of glucose and glycogen in your cells, blood, muscles, and liver, the excess will be converted to fat. And that’s how your pasta ends up on your hips.
