From page 148 of the third edition (2000) of Freeman, Freeman and Kelly’s “The Ketogenic Diet”.
Daily intake for a 13 month old child:
Commercial formula providing 28.3 grams of fat composed of equal parts high oleic safflower oil, soy oil and coconut oil, plus an extra 38.1 grams of almost pure omega six from from a standard safflower oil emulsion, a little soy protein 'n' glucose polymer. Vitamins and minerals. A maximum of 980ml of water in total.
This paediatric ketogenic diet is a child of its time, steeped in the benefits of massive PUFA ingestion and often combined with phenobarbitone. The child in the case study above could barely swallow as a result of the high dose of phenobarbitone she was taking. If you were to suggest hepatopathy, dyslipdaemia and potentially fatal pancreatitis as sequelae of the diet, I would not be surprised.
Please do not feed this to your child, we are no longer in the 1970s.
On the other hand, if you order a steak in a restaurant and it comes to you with salad and chips on the side, you do not HAVE to eat the chips to stop yourself developing fulminating pancreatitis.
If you are post-obese, via low carb eating, there is every likelihood that repeatedly consuming the chips (to avoid the pancreatitis, don’tchano) will cure you of the post-ness of your obesity. Enjoy the chips by all means.
