I used to do 36 hours a week, as an experiment. Not for weight loss. Maintained my weight.
Results: lower LDL cholesterol. Sharply lower. Blood pressure lower only while fasting.
Side effects: migraines. I tried to arrange it so there was not so much time fasting before sleeping but would usually wake up with a migraine.
Never fasted more than 2 days voluntarily.




Just coffee. I would eat a late breakfast one day, then stop eating, coffee (no calories) the next morning and then nothing until supper, usually around 8pm.
Yes the LDL went back up. I know it was related to the fasting and not weight loss - I am not fat and maintained calories overall to keep my weight stable. I had been sort of stumped, like you are. Obviously if someone is overweight and loses weight that will have benefits, there wasn’t a lot of research on people of normal weight fasting and not reducing. I got the one measurable benefit, but no improvements I could feel in any way, and the headaches were pretty bad.
