Most people have experienced the dreaded mid-afternoon energy crash, along with the intense sugar cravings that often accompanies it. This is a biological response to a combination of physiological factors. Once you understand the science, it’s easy to fix. Discover what’s really going on in your body, and how to stop afternoon sugar cravings instantly.
The Science Behind Your Afternoon Craving
You ate lunch. So, why are you craving something sweet just a few hours later? There are three main culprits driving you to reach for the chocolate mid-afternoon. Each of them alone is enough to induce cravings, but when they occur together (as they often do), it’s almost guaranteed you’ll be seeking something sweet:
- The cortisol dip: Cortisol is the alertness hormone. It follows its own daily cycle and naturally declines later in the day, leading to fatigue. Your brain may seek a quick energy source to compensate.
- The blood sugar roller coaster: A lunch high in carbohydrates causes a rapid increase in blood glucose, which is then followed by a steep crash. This crash triggers cravings as your body tries to raise sugar levels again.
- The protein deficit: Protein makes you feel fuller for longer. If you don’t eat enough protein, you’ll be hungry just hours later, making you susceptible to sweet food for a fast energy boost.
Mid-afternoon cravings can originate from what you did or did not eat at lunchtime. A fruit salad without protein, or something from the bakery just won’t work. To avoid an afternoon energy collapse, plan balanced lunches ahead of time, making sure to include protein, fiber, and whole foods. Definitely avoid processed carbs that will spike your glucose and leave you worn out and desperate for a lift by 3 p.m!
However, as much as you might plan ahead, cravings sometimes still happen. If you do find yourself experiencing a mid-afternoon crash, the good news is that there is a quick, easy, no-prep way to fix it:
How to Stop Sugar Cravings Instantly
The key is to stabilize your blood glucose, not spike it further. Protein and healthy fats digest slowly, providing a steady release of energy that prevents crashes and keeps you feeling full.
The ideal solution to sugar cravings is some hard cheese cubes (such as cheddar, swiss, or Gouda), paired with a handful of nuts. This savory combination provides protein, healthy fats and calcium, and requires virtually no preparation.
Other grab-and-go ideas include:
- A small bag of almonds and a piece of dark chocolate
- Low-sugar beef or turkey jerky
- A cup of plain Greek yogurt
- Apple slices with nut butter
Beyond Lunch — Other Drivers of Sugar Cravings
While your food choices are a primary factor, they aren’t the only possible cause. Two other powerful biological factors can trigger an intense afternoon sugar drive:
The Stress Connection
When you are under stress, your body releases high levels of cortisol because your brain perceives danger. This keeps you alert and ready for a fight-or-flight response. It therefore craves sugary, fatty and carb-heavy foods that provide a quick, temporary source of fuel and comfort. If your working day is consistently stressful, you may be caught in a daily cycle of stress eating.
When cortisol is elevated too often i.e. “always stressed out”, fat burning is decreased. Sustained high cortisol increases insulin resistance and stimulates fat accumulation – Boo!
The Sleep Deficit
A poor night’s sleep is another common culprit. Poor sleep disrupts appetite-regulating hormones, increasing the hunger hormone ghrelin and decreasing leptin, which is the hormone that makes you feel full. This imbalance makes you feel hungrier throughout the day, especially amplifying cravings for sugary or high-calorie junk food.
Building Habits to Prevent the Mid-Afternoon Crash
Quick-fix snacks will help when you’re in the middle of an afternoon sugar craving. However, the ultimate goal is to prevent them. Here are some strategies to address the root cause of the issue and stop sugar cravings in the long term:
- Front-load your protein: For example, add eggs to your breakfast, and eat at least a palm-sized portion of protein (like chicken, fish, or beans) at lunch.
- Hydrate strategically: Set a reminder to drink a full glass of water around 2:30 p.m. Dehydration is often mistaken for hunger and can exacerbate fatigue. Fortunately, this one’s easy to avoid!
- Take a short walk: Just a few minutes of gentle exercise can boost your circulation and energy levels. If your mid-afternoon blues are partially due to stress, this can help reset your focus without needing to eat. Take a 10-minute walk if the mid-afternoon cravings creep in.
- Prioritize sleep: Better-quality sleep can help stabilize your appetite hormones, leading to fewer cravings and crashes. Stay away from screens after 7 pm. Limit alcohol – it disrupts deep sleep.
Your Simple Plan to Beat Afternoon Sugar Cravings
Beating your afternoon sugar cravings is about understanding your body. It has nothing to do with willpower. Planning ahead for healthy lunches and snacks is the best fix. However, you can stop sugar cravings instantly once you understand how cortisol, blood sugar, and protein work together. Have some protein-rich snacks ready for next time the cravings strike, and always plan ahead to build nutrition habits for long-term success!
