I fast for 23 hours everyday and consume around 1500 calories within the 24th hour. Is this a good or bad diet plan? I'm female, 5'9", aprox 145 lbs.

..Not Physiologic. 20 y/o female says she Fasts23hrs everyday & consumes 1500calories within the 24th hour; asks if good or bad diet plan. Definitely Not Physiologic. Cars, Ships, Airplanes etc perform Optimally when the manufacturers recommendations are followed. So too the Human body when it goes with the natural rhythm of Life. One with so much discipline can certainly find a way to accommodate natural Physiology.
