| I fast once or a twice a year for 3-6 days, and I practice "one meal a day" most of the year. My first fast was difficult, I did not supplement with electrolytes, slept too much and basically spent the duration watching series and feeling awful. It is much better to go outside, work and try to follow your regular habits. Electrolytes supplements are a must, and also some paracetamol during the first few days to reduce the inconvenience of your brain switching from glucose to ketones. Fasting is easier the more you do it, partly because of calibrated expectations and less fear but I also think that the body simply adapts. The only difficult day is the first one, for me. The mental clarity thing is not a boost, you won't gain IQ points or intellectual stamina, more like slightly enhanced mood and more stable/regulated mental performance. |
