If you are concerned about ketosis and want a gradual plan, look at the schwarzbein program. The two plans are somewhat similar but there is a higher carb allotment on Schrzbein at least initially. Good way to ease into eating this way. My family had no complaints when I started them eating that way. It is a long term wol though. The weight will not fall off as quickly, wieght loss is actually a side effect of what she is trying to achieve; healthy adrenal glands and insulin sensitivity. Good luck.
