Smelling some unique flavors can suppress appetite or promote metabolism to help lose weight, but smelling incense takes effect quickly and fails quickly. Some people will be particularly sensitive to these smells, and some adverse reactions may occur if they smell them frequently. Therefore, losing weight by smelling incense is not a long-term solution. To lose weight, we must adhere to a healthy diet and scientific exercise. In terms of diet, it is necessary to control the total calorie intake, eat less greasy and sugary foods, and eat more foods rich in dietary fiber, such as vegetables, fruits and coarse grains. In sports, we insist on combining Li Xing training with aerobic exercise, burning fat and exercising muscles at the same time.
