When a woman is over 30, she usually becomes very stressed. During the day, she has to face a difficult boss, and at night, she has to wash clothes, cook and take care of the children. Basically, she has no time to take care of herself. When women are stressed, stress hormones are easily produced in the body. This substance will accelerate the conversion of blood sugar into fat and make her brain dull. Sometimes I feel nothing when I eat too much.
