Why Do I Crave Sugar Every Afternoon?

The 3 p.m. slump is common. Here's what's usually behind it, and simple ways to break the loop.

If you hit a wall mid-afternoon and suddenly need something sweet, you're far from alone. Several things tend to stack up at that time of day.

1. The lunch rebound

A meal heavy in refined carbs can raise blood sugar quickly. When it drops back down, many people feel tired, foggy and hungry again, and the body asks for fast fuel.

2. Your natural energy dip

Your internal clock includes a natural dip in alertness in the early afternoon. Combine that with a carb-heavy lunch and the slump gets deeper.

3. Short sleep

Poor or short sleep is linked with stronger hunger signals and a bigger appetite for sweet, high-calorie foods the next day.

4. Stress

Stress hormones can push cravings toward quick comfort foods, and the middle of a busy workday is when stress often peaks.

Simple ways to break the loop

• Build lunch around protein and fiber. Add vegetables, beans, eggs, fish or meat, and go lighter on refined carbs.
• Take a 10-minute walk after eating. Light movement after meals helps your muscles use glucose.
• Drink water first. Mild dehydration can feel like fatigue or hunger.
• Plan a better snack. Nuts, Greek yogurt or an apple with nut butter beats a vending machine raid.
• Protect your sleep. It's the least glamorous fix and often the most effective.

When to see a doctor

If you're constantly thirsty, urinating often, losing weight without trying or feeling exhausted no matter what you do, talk with your doctor. Those can be signs worth checking.
