Here's some fun facts about why you should never send your child to bed without dinner as a punishment and why doing it not only makes you a bad parent but causes them physical harm long-term.
Skipping meals is the absolute worst way to lose weight as anyone in the practice will tell you, since it shoves your metabolism down a hole in an attempt to store fat since going hungry tricks your body into thinking that you're starving to death. Aka, your child will likely suffer obesity down the line and it'll be an utter pain to fix.
And
Going to bed hungry makes it hard to sleep. Y'know why you fall asleep easier with a full stomach in a warm area? Well, you're comfy and you're probably having one of those legendary "food comas" that frat boy down that hall was talking about last week. If you give your child this punishment frequently, they're likely to have long-term insomnia, which is really not good for their Mental Health. (Personal experience)
