If I can ever amass enough moral fiber I will try one day fast the next eat almost ad lib but only items of high nutrition and as low a glycemic index as practical - seems to work well for some on the CR-ON forum - or perhaps a 2 day per week fast like the 2 least stressful days in your week - whatever works - my diet is one long ever changing experiment.
