Underweight vs. Overweight: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Updated on November 18, 2023
Underweight refers to weighing less than what is considered healthy for a given height, while overweight is weighing more than what is healthy.

Key Differences

Being underweight means having a body weight lower than what is deemed healthy for a person's height, often indicating inadequate nutrition or underlying health issues. Overweight, conversely, refers to excess body weight compared to standard height-weight charts, often due to excess body fat.
