I still do it mate and I have maintained by weight over the past year.
Usually Monday - Thursday while I'm at work.
Fast from about 21:00 to 12:00ish the next day.
Hods of food after exercising. I didn't bother with the BCAA or whatever before strength training and I'm mostly only running now.
It's just about getting into a bit of a routine.
What do you eat before exercise please?
I have done some exercise in a totally fasted state but I felt a bit 'weak'. Therefore I have been drinking a shake about an hour before a run or if I do some free weights. Shake is water/milk, crushed banana, honey and myProtein powder stuff but when it runs out I won't buy any more. After the run I eat a bagel + chicken breast or hard boiled egg and then eat over the next 6 or 7 hours, main meal at 8ish when I return home.
I don't eat anything before I exercise now. Biggest exertion of the week is usually on a Saturday so I'll start the fast at 8ish on the Friday, go for a run at around 09:00 and then have usually a bagel with salmon and/or eggs at 1/2ish. At first this was making me feel quite ill but I've started to have a berocca-type hydration tablet (9 calories) before the run and some disolvable B Vitamins during the run, which seems to help.
