I haven't see any reported cases of CRC dramatically responding to simple fasting, or separately, ketogenic diets, amongst the brave souls that tried them. Nevertheless I do suspect there are some potential health benefits with some big caveats. We certainly cut down on the carb content of meals the first year or two, fairly aggressively, but not a consistent keto diet. I still think it was a good move, certainly there were benefits to weight control, inflammation, cholesterol, HgbA1C, and FBS.
1. The ketogenic diets tend to be difficult for most people to achieve and sustain ketosis.
2. Not all ketogenic diets are equal. They can be built out of different protein and fat sources, with the question of which components or combinations are best. Also lurking in the background discussions, are the important non starch/sugar components of vegetables and fruits that may contain important aspects of cancer nutrition e.g. flavonoids and special fibers
3. Various sugar-cancer propositions are pushed too simplistically, with the cancer cells likely stripping the body of carbs and proteins. A simple fast can lose weight quickly and miss important nutrients to boot. Likewise keto diets with adequate energy intake can still miss important nutrients from inadequate vegetable and fruit extract intakes. There has long been some preclinical evidence that higher levels of flavonoids can do interesting things in cancer on a contributory basis, so a keto diet devoid of them may be counter productive, whatever the merits of induced ketosis. Also IGF-1 levels are related to carb intakes both in the short term sense with sweetners (including some non sugars) and obesity, so a potential positive merit for keto diet.
4. Failed keto dieters can put on pounds per day if they rebound and eat a high carb/high fat diet...
5. To inhibit glucose utilization in cancer cells we also use IV vitamin C.
