Meal Prep: Stress Free Eating

Aventry Health Editorial Staff

In today’s fast-paced world, we often underestimate the daily mental load of feeding ourselves. Whether it’s choosing what to cook, grocery shopping, or managing time to prepare meals, the process can trigger stress responses that quietly wear us down.

But science shows that meal prep can counteract this daily strain—not just by saving time, but by improving how your brain and body handle stress.

The science of stress and food

When you're under stress, your body releases cortisol, a hormone that influences everything from your appetite to your sleep. Elevated cortisol levels are associated with:

• Increased cravings for high-sugar, high-fat “comfort” foods

• Blood sugar instability

• Impaired decision-making and impulse control (yes, even at mealtime)

• Weight gain, especially around the abdomen

Research published in Appetite (2016) found that people experiencing chronic stress were more likely to engage in disordered eating behaviours, including overeating and emotional eating.

How meal prep lowers stress

1. Reduces decision fatigue: We make over 35,000 decisions a day, and food choices are some of the most frequent and mentally taxing. By planning meals in advance, you offload that daily cognitive burden.

   
   

2. Stabilizes blood sugar: Prepping balanced meals in advance helps you avoid skipped meals or impulsive choices that lead to blood sugar spikes and crashes.

   
   

3. Supports healthy eating habits: When healthy food is already made and ready to eat, you're more likely to make better choices. This is known as "choice architecture"—designing your environment to support healthier behaviours.

   
   

4. Improves time management: Prepping meals just once or twice a week can save you hours throughout the week—not to mention reduce the pressure of figuring out what to eat when you’re already hungry and tired.

Some final thoughts…

Meal prep isn’t just a trendy life hack—it’s a scientifically supported way to reduce stress, support your health, and improve your relationship with food.

By investing a few hours in meal planning and prep each week, you’re creating space for better mental clarity, physical health, and emotional wellbeing.
