UP day = eating 100% of one's normal Burn
Adding to my above-post regarding JUDDD.
An UP day in JUDDD (or any Alternate Day plan) is supposed to be just a Normal, Maintenance day.
Meaning a day in which a person eats his or her total, normal day's calorie burn.
Bear in mind that my current Plan is to eat 100% of my burn rate on UP days,
and 45-50% of my burn rate on Down days.
There are larger, younger females who have a daily burn of around 2000 calories, in that case it would be appropriate for them to eat 2000 on UP days.
However, since my normal day's total calorie burn is only between 1000-1100, that is the appropriate amount for me to eat on my UP days.
I've found that on Down Days I am not able to consistently follow through with eating only 20% of my burn rate as is recommended by Dr. Johnson (which for me is only around 220 calories).
Even 300 calories per Down day has proven to be too low for me to succeed with long-term,
and so I increased that amount to 500 calories...which is about 45 to 50% of my current total daily burn rate.
