Abstract: Provided is a body weight control method for a pet, including a body weight reduction step of feeding pet food, which has a moisture content of less than 25%, and a protein content of 20% by mass or more in terms of dry matter and a soybean-derived ingredient content of 5% to 30% by mass in terms of dry matter with respect to the total amount of pet food, to a pet daily for a period of 20 days to 100 days in a feeding amount that meets a daily energy requirement of 70×kg BW0.75, in which a body fat percentage of the pet immediately after completion of the body weight reduction step is reduced by 5% or more with respect to a body fat percentage of the pet at a start of the body weight reduction step.
