Personally I don't tend to worry to much about the food side of things even though I do try and make sure they are empty.
I can't see that a tortoise in the wild will starve itself for three to four weeks they will have a limited amount to eat I'm sure but if it gets warm enough to eat I'm sure they will and then if the temp drop again being a reptile they will sleep again.
It's the same with tortoises that are carrying eggs some people say don't hibernate them but mine have hibernated with eggs and as soon as awake they tend to get rid of them again I'm sure this happens in the wild.
I think a lot of the information we tend to think as gospel is very outdated hence we tend to get an awful lot of people that are to frightened to hibernate.
These are my thoughts please don't shoot me.
