As a rule, I shy away from extreme diets or eating regimens. Atkins? Never heard of him. Whole 30? Wholly not going to bother with it. Paleo? Some things are better left in the history books. However, the simplicity of the ketogenic (keto for short) diet appealed to me, and seeing as I had a wedding to attend—and a bridesmaid's dress to wear—I needed something effective to help me shed some weight, and fast.
