Sugar for Stress? Here’s What You Should Know

Jan 13, 2025 | General Health

When you think of stress relief, sugar might not be the first thing that comes to mind. In fact, sugar often gets a bad rap in the world of nutrition. But did you know that sugar can actually support your metabolism and help reduce stress? 

This idea stems from the work of Ray Peat, a biologist and researcher who believes that sugar plays a vital role in keeping our bodies balanced, especially during stressful times. While a balanced and healthy diet is key for overall health, let’s take a closer look at how and why sugar can help during stressful times.

How Does Stress Affect Your Metabolism?

Stress has a way of throwing our bodies out of balance. When we’re stressed, our bodies produce more cortisol, a hormone that helps us cope with stress but can also wreak havoc on our metabolism when it stays elevated for too long. Cortisol can lower your blood sugar levels, slow down your metabolism, and even make you crave more sugary or high-fat foods. Over time, this can lead to fatigue, weight gain, and an overall sluggish feeling.

So, where does sugar come in? According to Ray Peat, sugar—specifically from natural sources like fruit and honey—helps regulate the body’s stress response and keeps metabolism functioning smoothly. By supplying your body with easily accessible energy, sugar helps reduce the demand on your adrenal glands to produce more cortisol, which, in turn, can lower your stress levels.

However, it’s worth noting that too much sugar combined with processed foods can have the opposite effect and actually increase stress (and inflammation) throughout the body.

Yet, natural sugars—from fruits and honey specifically—offer quick energy to the body, which helps stabilize blood sugar levels and provides immediate relief from stress. Additionally, these natural sources of sugar are packed with vitamins, minerals, and antioxidants, which further support the body, especially when under stress.

Why Low-Carb Diets May Increase Stress

Many popular diets today promote low-carb or sugar-free approaches to weight loss and health. However, Ray Peat’s research suggests that restricting carbohydrates—especially sugars—can actually increase stress on the body. When your body is deprived of glucose, it has to work harder to produce energy, often by breaking down muscle tissue or ramping up cortisol production. This can leave you feeling more tired, anxious, and stressed.

In contrast, Peat argues that including moderate amounts of natural sugars in your diet can keep your body running efficiently. Sugar provides quick, easy-to-access fuel that supports your brain and muscles, reducing the need for your body to activate stress responses like the release of cortisol.

How to Incorporate Healthy Sugars Into Your Diet

So, how can you use sugar to support your metabolism and reduce stress without overdoing it? Here are a few simple tips:

  • Choose natural sugars: Opt for natural sources of sugar like fruits, honey, and even dairy products. These foods not only provide glucose but also offer other nutrients that are beneficial for your overall health. And remember, portion sizes are important!
  • Balance your meals: Pair natural sugars with healthy fats and proteins to prevent blood sugar spikes and crashes. A good balance of macronutrients can help maintain stable energy levels and keep stress at bay.
  • Listen to your body: If you’re feeling fatigued, jittery, or stressed, it might be your body’s way of telling you that it needs more fuel. Don’t be afraid to reach for a piece of fruit or a spoonful of honey to give yourself a quick energy boost.
