I found a piece at (I think) Mark's daily apple, suggesting that under 150g carbs could be a good target for weight maintenance, so I figured that it would be suitable for feast days. I also remember from the interview with Voltek and Phinney (link in resources I think) that they said the obesity and diabetes epidemic coincided with an increase in a population wide average daily carb consumption of about 50g and so, looking at my previous average consumption I figured that 150g would represent a 50g drop.
However, Peter Attia points out that people's tolerance to carbs varies so some need to cut out more than others. My feeling is that it's worth starting by reducing your carbs by 50g and see how you respond.
