There is a fair amount of controversy over the basic question of how people gain weight. Is it simply a matter of energy intake being greater than energy expenditure? Or is there more to it; do the type of calories we eat matter and can avoiding certain types help to lose or prevent weight? The various low-fat, low-carb, and glycemic index advocates can’t seem to agree on which it is.
However, most can agree, and logical sense would tell us, that drinking 500 calories of soda is not equal to eating 500 calories of fruits and vegetables. One is simply “empty” calories—those that provide no real nutritional benefit and don’t do much to combat hunger.
Whether you ascribe to the simple idea of trying to burn more calories than you take in or focus on avoiding certain types of calories, you want to minimize intake of empty calories, and maximize nutrient-dense calories.
