Ketosis is not some magical mind state.
When all glucose and glycogen reserves are exhausted, body will start producing energy by burning fat reserves. To do so it needs to produce ketones. When low or glucose body will gradually start switching to ketosis to supplement energy needs and eventually fully switching to ketosis and only way of producing energy.
When glucose is available it will be used as primary 'fuel' source again.
That is a reason why after fasting its important to ease in the cards and sugars.
- beagle3 6y agoThat's a reason, but likely not the only reason. There are likely reasons relating to regulation of other digestion processes that slow down to a halt while fasting. Coming up from a fast and eating a lot of food quickly may cause refeeding syndrome - regardless of whether it is carbs or protein/fat. Switching back to carbs from pure fat or pure protein is not dangerous in the same way, AFAIK (but I'm not a doctor).
