i did that years ago (1970-1980) back then i think we called it atkins,,, it worked,, gave you incredible muscle tone (we,,, as in the whole team) did it so 'exercise' was already part of our program. as i have aged i am not fat,, but wouldn't mind dropping about 10-15lb,,20 would make me look boney. (sp).. i sometimes fast for 3 days,, sometimes up to 6 just to detox not weight loss.......i feel fine except a little hungry first few days.
fasting has helped me to raise my heart rate,, my bp stats are always well under 100 on both numbers....family/doctors call me 'near dead'----(yes i have a fear of being buried alive,, so there are several stupid rules before i can be buried-dont follow the rules,, dont show up for the will reading)
