**Abstract**

To truly eliminate the possibility of diabetic foot ulcers, the elimination of the symptoms of diabetes is essential. There are many forms of diabetes and there is no one diet that is effective for all patients. It is essential that a proper diet is utilized and for most diabetic patients a reduction in weight and the restoration of a properly balanced microbiota can eliminate the devastating effects of diabetes including foot ulcers. This review examines in detail the different types of diets, and how they affect the host and the microbiota to eliminate as much as possible the risk of foot ulcers. Microbiota, diet, incretins, and insulin all directly affect the deposition of fats which causes insulin insensitivity and diabetes in most patients.
