Answer: The foundation for weight loss continues to be based on physical activity and diet. Take in fewer calories than you burn, and you lose weight. The 2015 Dietary Guidelines for Americans recommends cutting calories by 500 to 700 calories a day to lose 1 to 1.5 pounds (0.5 to 0.7 kilograms) a week.
