Most people know the feeling: After a night out, your body craves burgers, pizza, or fries. The urge seems almost irresistible, but is junk food really a good solution for hangovers? The answer isn’t as simple as you might think.

Why You Crave Junk Food After Drinking

When you drink alcohol, it affects your brain’s appetite regulation. Alcohol inhibits the production of leptin, the hormone that normally signals fullness to your brain. As a result, you experience intense hunger – especially for calorie-dense foods. Additionally, alcohol causes blood sugar levels to fluctuate, which triggers cravings for quick carbohydrates and fat. That’s why a greasy pizza or burger seems so tempting after a night out.

The Pros and Cons of Junk Food After a Night Out

There are actually some benefits to eating junk food after drinking. It fills you up quickly, temporarily stabilizes blood sugar levels, and can help restore your salt balance, which alcohol disrupts. However, there are also downsides:

  • Digestive issues: Alcohol irritates the stomach, and greasy junk food can make it worse, leading to nausea and bloating.

  • Worsened hangover symptoms: While junk food may provide a temporary energy boost, your blood sugar will crash again, increasing fatigue and headaches.

  • Poor sleep quality: Eating fatty foods right before bed can disrupt sleep, making it harder for your body to recover.

What Should You Eat Instead?

If you want to avoid the worst hangover symptoms, there are better alternatives. Complex carbohydrates from whole grain bread or oatmeal can stabilize blood sugar without causing drastic fluctuations. Protein from an omelet or yogurt provides satiety without overloading your stomach. Additionally, staying hydrated is crucial – drink plenty of water or an electrolyte-rich sports drink to help your body recover.

So, while junk food might seem like the perfect solution in the moment, it can actually make your hangover worse. Simple alternatives can help your body recover more effectively – and make the day after a little easier to handle.
