It is best not to drink soybean milk when eating bread. Cake and tofu are a fat combination. I think bread and soybean milk are different, too, hehe. As far as what you eat at present is concerned, it should not be fat, but the nutrition is not balanced. Your diet lacks vitamins and fiber. You should eat more fruits and vegetables to promote digestion and avoid fat accumulation. Besides, it may be time to lose weight. Your body has adapted to your diet and exercise and is no longer thin. It is suggested to increase the intensity of exercise or change the way of exercise.
