There was this guy in Poland, an MD, who figured this exact thing in 60s. He essentially took and modified the damaged liver diet (rich in MCTs mostly) and have it in a series of trials, lightly controlled, vs a plain lower calorie diet, to a bunch of people in sanatoriums. He derived the diet from basic principles and then available dietary tables - being forced into service but the military he had to learn dietetics. Extremely sick people who could barely walk. The results were pretty resounding, so good they made whole Polish Academy of Sciences at the time recoil and denounce him. He was thought to have committed fraud. They stopped denouncing him repeatedly only in some 2000s. This was the more correct grandfather of better known Atkins diet. It has some uses. One of them is rapid weight loss, the other is diabetes, hepatitis recovery, a few connective tissue diseases and epilepsy refractory to treatment. It is driven by explicit testing for ketosis and microelement and vitamin tables. And the difference is it's an actual process not just one flat prescription.
