There is no harm in navel dripping essential oil to lose weight. It is enough to do aerobic exercise such as jogging, brisk walking, skipping rope, playing badminton, gymnastics, swimming and yoga for more than 30 minutes every day. Eat more fruits and vegetables and drink more water. Be careful not to eat anything after 8 pm, refuse all puffed food, preserved fruit, candied fruit and sweet drinks (except freshly squeezed juice), and eat less.
