"Did you eat today?"
It sounds like something your mom texts when she’s worried, or maybe a casual check-in from a roommate who noticed the fridge hasn't been opened in eight hours. But honestly, it’s becoming one of the most significant diagnostic questions in modern wellness. We live in a world where "hustle culture" rebranded starvation as "intermittent fasting" and where high-cortisol workdays literally shut down our hunger signals. When someone asks if you’ve eaten, they aren't just asking about calories. They’re asking if you’ve checked in with your body’s most basic survival requirements.
Most of us fail this check-in more often than we’d like to admit.
The Biology of Forgetfulness: Why "Did You Eat Today" Matters
Hunger isn't just a growling stomach. That’s a common misconception. By the time your stomach is making noise, you’re already deep into a blood sugar crash. The brain consumes about 20% of your body's total energy. When you skip meals, the first thing to go isn't your physical strength—it's your emotional regulation.

Ever heard of "hanger"? It’s real. Science backs it up.
When glucose levels drop, the brain perceives it as a life-threatening crisis. It triggers the release of adrenaline and cortisol. Suddenly, a minor email from your boss feels like a personal attack. You get snappy. You lose focus. You might even feel shaky or lightheaded. If you’ve ever found yourself spiraling into a bad mood for "no reason," the answer to did you eat today is usually the smoking gun.
Dr. Deanna Minich, a nutrition scientist and Fellow of the American College of Nutrition, often discusses how colorful, consistent eating impacts more than just the scale—it impacts the "inner atmosphere" of the human mind. If the fuel isn't there, the machinery grinds. It’s physics.
The Stealthy Erasure of Appetite
We have a weird relationship with food in 2026. Stress is a massive appetite suppressant for a huge chunk of the population. High levels of stress hormones can lead to a condition called "anorexia of aging" or just general stress-induced loss of appetite. Basically, your sympathetic nervous system—the "fight or flight" mode—takes over.
Think about it. If you were being chased by a predator, you wouldn't stop for a sandwich. Your body shuts down digestion to prioritize running. Today, our "predators" are deadlines and social media notifications. We stay in fight-or-flight for ten hours straight.
Then there’s the caffeine factor. We drink coffee to stay awake, but caffeine is a powerful stimulant that masks hunger cues. You might feel "fine" at 2:00 PM, but you’re actually running on chemical fumes.
Beyond Calories: The Nutrient Gap
Eating isn't just about stopping the hunger. It’s about the quality of the "yes." If the answer to did you eat today is "I had a handful of crackers and a diet soda," your body is still technically starving for micronutrients.
Magnesium. Zinc. B-vitamins.
These are the building blocks of neurotransmitters like serotonin and dopamine. If you aren't eating whole foods, you aren't just tired; you’re literally unable to manufacture happiness at a chemical level. It’s a harsh truth. You cannot supplement your way out of a bad diet, though many try.
Why the Question is a Social Lifeline
In many cultures, asking "Have you eaten?" is the equivalent of saying "I love you." In Korea, the phrase Bap meogeosseoyo? is a standard greeting. It’s a way of checking on someone’s soul by checking on their stomach.
When we ask our friends did you eat today, we are acknowledging that they are a biological organism with needs, not just a productivity machine. It’s a grounding technique. It pulls the person out of their head and back into their physical form.
The Actionable "I Forgot to Eat" Checklist
If you find yourself constantly reaching the end of the day and realizing you’ve survived on nothing but air and spite, you need a system. Willpower isn't enough because willpower requires glucose—the very thing you’re missing.
- The "Mechanical Eating" Rule. If your hunger cues are broken due to stress or ADHD, don't wait for them. Eat at 8, 12, and 6. Set an alarm if you have to. It feels robotic, but it keeps the brain stable.
- The Power of Liquid Nutrition. When your stomach feels "closed" due to anxiety, don't force a heavy meal. A smoothie or even a glass of whole milk can provide the protein and fats needed to stabilize blood sugar without making you feel nauseous.
- The "Big Three" Check. Every meal should have a protein, a fat, and a fiber. If you're missing one, you'll be hungry again in sixty minutes.
- Protein First. Always. Start your day with 30 grams of protein. Research suggests this significantly reduces late-day cravings and keeps your focus sharp through the afternoon slump.
Dealing with Chronic Under-Eating
If the answer to did you eat today is consistently "no" or "hardly anything," it’s worth looking at the why. Is it a lack of time? Is it a sensory issue? Or is it something deeper, like disordered eating or a physical ailment?
Sometimes, the gut-brain axis is just misaligned. Gastroparesis (slow stomach emptying) or even common gut dysbiosis can make the thought of food unappealing. If you’re genuinely never hungry, it’s time to see a functional medicine practitioner or a registered dietitian. This isn't just about being "forgetful." It’s about your foundational health.
The Immediate Next Steps
You’ve read this far. Now, stop.
Assess your current physical state. Is your mouth dry? Is there a slight tension behind your eyes? Is your mood a little brittle?
Go to the kitchen. Don't look for a "snack." Look for fuel. A piece of fruit and some peanut butter. A hard-boiled egg. A handful of walnuts.
The goal is to move from a state of depletion to a state of maintenance. You don't need a five-course meal, but you do need to acknowledge that your body is a vessel that requires physical input to produce mental output.
Prioritize a 30-gram protein hit within the next hour. If it’s late at night, opt for something with complex carbohydrates and tryptophan, like oatmeal or a turkey slice, to help transition your nervous system into "rest and digest" mode.
Stock your "Emergency Hunger" drawer. Keep non-perishable, high-density foods like sardines, beef jerky, or protein bars in your workspace. When you realize you've hit that mid-afternoon wall, you won't have to make a decision—you'll just have to eat.
Check in on one person. Send a text. Ask them: did you eat today? You might be the only person who asks, and it might be the reminder they desperately need to step away from the screen and take care of themselves.
