How Detecting Hunger Shapes Our Mood: The Science Behind Hangry
A month-long study with 90 healthy adults using continuous glucose monitors and smartphone mood checks found that mood worsens primarily when people perceive hunger, not simply when blood sugar drops.

The piece, republished from The Conversation, also notes the everyday relevance for parents managing kids' meals.
