Is skipping breakfast bad for your health?

The evidence on skipping breakfast is more nuanced than the old "most important meal of the day" messaging suggests. For most healthy adults, skipping breakfast is not inherently harmful. That slogan was largely popularized by cereal companies and is not strongly supported by science. Research shows mixed results. Some studies link breakfast skipping to higher obesity risk, but this may reflect broader lifestyle patterns rather than the meal itself. Intermittent fasting, which often involves skipping breakfast, has shown health benefits for many people. What matters more is overall diet quality and total calorie intake throughout the day. People with diabetes or certain medical conditions may genuinely need to eat in the morning, but for healthy adults it largely comes down to personal preference and what helps them eat well overall.
