She forgot to mention that ketogenic diets might cause bad breath, otherwise all the usual shibboleths are here. She implied that the diet could kill you.
One of her biggest gripes is that rapid weight regain is a problem after you go off the diet. But that’s a problem with all diets.
If you keep eating like most Americans, you’ll be fat like most Americans.
Clearly, I disagree with much of what the dietitian writes. Under “Categories” on the left side of this page, click “ketogenic diet” for details.
Here’s a taste:
“Limited food choices are not the only unglamorous part of the diet. In order to detect if your body is in ketosis, you must pee on a stick that will detect ketones in your urine. You will also experience some intense side effects. The combination of cramps, constipation, irritation, brain fog, insomnia, and more that are common during the start of the diet are labeled the “keto flu.” Symptoms seems to last anywhere from a week to a month until your body becomes accustomed to ketosis.”

Diabetic Mediterranean Diet 
I am glad I have normal human weight and in perfect heath following the ADA diet.
My mother’s diabetes and kidney disease progressed relentlessly under current CDA dietary guidelines. Constant changes to medications, increased insulin resistance and finally dialysis.
