Dr. Sebi diet, also called the Dr. Sebi alkaline diet, is a plant-based diet developed by the late Dr. Sebi. This diet is based on the African Bio-Mineral Balance theory and was developed by the self-educated herbalist Alfredo Darrington Bowman - better known as Dr. Sebi.The diet consists of a specific list of approved vegetables, fruits, grains, nuts, seeds, oils, and herbs. As animal products are not permitted, the Dr. Sebi diet is considered a vegan diet.most foods on this diet are low in calories, except for nuts, seeds, avocados, and oils. Therefore, even if you ate a large volume of approved foods, it's unlikely that it would result in a surplus of calories and lead to weight gain.
