Many people believe modest overweight does not pose any health risks. A global meta-analysis of almost 4 million adults who never smoked and had no chronic conditions at baseline found all-cause death rates were the lowest when BMI was normal (20-24.9). Death rates increased significantly and linearly when BMI was above 25. BMIs below 20 also increased risk.
