The FT reported that airlines could save money by reducing passenger weight. The amount of benefit from using fat-burning drugs could reach $580 million. As Financial Times analysts calculated, reducing the average weight of 178 passengers by just 10% on board a Boeing 737 would reduce takeoff weight by 2%. This figure will significantly reduce fuel costs. To make their ships lighter, carriers are removing olives from the menu, using the lightest possible dinnerware and reducing the weight of beverage carts.
