Neither Golden Flavor Calcium Fortified Oligosaccharide Cereal or Golden Flavor Original Cereal is the best choice for weight loss. While they are both rich in nutrients, such as dietary fiber and protein, which can increase satiety, they do not directly lead to weight loss.

Both cereals can be used as part of a healthy diet to provide dieters with essential nutrients such as carbohydrates, fat and protein. However, the key to weight loss lies in the balance of total calorie intake and physical exercise. Therefore, if you want to improve your body fat, you need to properly control your total calorie intake and increase your exercise.

Overall, no matter which cereal you choose for breakfast, you need to pay attention to controlling total calorie intake and adhering to exercise exercise in order to achieve weight loss. If you have special nutritional needs, you can consult a professional dietitian or doctor for advice.
