Can someone please explain this: 都没吃饭吗 I was watching a drama and in the scene, the coach was speaking to her team:

Coach: 希望每个队员都能拿出最好的状态。能不能做到 (I know all of you can do your best。 Can you do that?)
Team: 能！(Yes!)
Coach: 都没吃饭吗 (Not loud enough!)

Can someone please explain to me why &quot;都没吃饭吗&quot; can mean this? Would you ever use that to ask if your friends have eaten?
Thank you!!
It means the coach thinks the players are not energetic enough as if they were hungry.
This sentence can only be used in some situations:

a coach blames the players being not energetic enough
an officer blames the soldiers being not powerful enough
fighter ridicule the opponent being so weak

or similar. Always considered as a blaming or ridiculing.
If you ask a friend about eating, it would be “吃饭了吗？” instead of “没吃饭吗？”.
