I don't know if smelling apples is good for your health. Eating apples is helpful to lose weight, but apples themselves don't lose weight! Because eating apples can make you feel full and eat less other foods! Reducing the absorption of fat and calories helps to lose weight! I have a classmate who lives in Xia County. She has a lot of fruit. She doesn't eat much every day, mainly apples! She is still very fat, about 130 kg! So eating apples is good for your health, but it has no obvious effect on losing weight!
