A full 7 days? I think I would loot a McDonalds by day 5.

I am toying with the idea of extending one of my IF days to 48 hours instead of 24. For example - eat 3 meals on Sunday, the last one being an early dinner. Eat the next meal on Tuesday night, 48 hours later. I would only have to sleep on an empty stomach one night (Monday). Tomorrow is an IF day on my 5:2 with the normal routine being to eat only supper. Maybe I will push it into Friday before I eat.
