Judaism has a long rich history of Loopholes.
It is not only Judaism. I seen this movie before.
Here is what qualifies as a fast on one of the Holiest days of the year.
Four egg omelet at breakfast with no meat.
Two tuna fish sandwiches for lunch. Each about an inch thick. Throw in either apple/cherry pie with ice cream on top.
Pound of shrimp for dinner. Sides of mac/cheese and butter noodles.
After that fast I can't eat for a few days.
