Shortcuts Keto Gummies - Due to my A1C going to 5.4-5.6 my Dr. lowered the dose to once per day and I very soon after the change noticed a craving for sweets again and weight gain of 8 pounds over 6 months. I do believe that Metformin decreases appetite and cravings thus the weight loss. I also make an assumption that increased utilization of the sugar and interference with storage of sugar also interferes with weight gain. I find that my appetite and cravings are reduced while on metformin.
