You cannot debunk a notion that’s not a “notion” to begin with? These “debunking” (“hype”) citations (“notions”) are kind of like “Elvis Sightings?”
What she is referring to IS NOT a “ketogenic diet” by today’s standards; this is what she linked her conclusion to:
”…Over the course of the study, each subject was instructed to attend 22 dietary counseling sessions with a registered dietitian; average attendance was 66% for both groups. During the first two months of the study, the low-fat group was instructed to consume only 20 g of fat per day and the low-carb group only 20 g of carbs per day. However, they were not expected to stay at these levels indefinitely: at the end of this 2-month period, they started adding fats or carbs back to their diet until they felt they’d reached the lowest intake level they could sustainably maintain. Neither group was able to stick to the very low starting intakes: by month 3, the low-fat group was already consuming an average of 42 g of fat per day, whereas the low-carb group was consuming an average of 96.6 g of carbs per day.
It’s possible some in the low-carb group may have been in ketosis during these first two months due to the very low carb intake prescribed. While the low-carb group was able to achieve reduced carb intake throughout the trial (≈115 g/day), only a very small minority reported consuming ≤50 g/day— the intake threshold typically required to stay in ketosis.[6] …” Low-fat vs low-carb? Major study concludes: it doesn’t matter for weight loss
[6] THEMATIC REVIEW Definition of low-carbohydrate diet: Much of the controversy in the study of LCDs stems from a lack of a clear definition. The rationale of carbohydrate restriction is that, in response to lower glucose availability, changes in insulin and glucagon concentrations will direct the body away from fat storage and toward fat oxidation. There is a suggestion of a threshold effect, which has led to the clinical recommendation of very low concentrations of carbohydrate (20–50 g/d) in the early stages! of popular diets. This typically leads to the presence of measurable ketones in the urine and has been referred to as a very-low-carbohydrate ketogenic diet (VLCKD) or a low-carbohydrate ketogenic diet (LCKD). Potent metabolic effects are seen with such diets but, beyond the threshold response, there appears to be a continuous response to carbohydrate reduction. The nutritional intake of 200 g carbohydrate/d has been called an LCD, but most experts would not consider that to provide the metabolic changes associated with an LCKD. We suggest that LCD refers to a carbohydrate intake in the range of 50–150 g/d, which is above the level of generation of urinary ketones for most people. Low-carbohydrate nutrition and metabolism
