Many of us are well aware of the adverse effects of stress on our mental and physical state. However, one lesser-known consequence is its ability to cause weight gain. Whether it’s turning to comfort foods or having trouble sleeping, stress can prompt us to make choices that hinder our efforts to maintain a healthy weight.
In this article, we’ll explore how stress can cause weight gain, examine the science behind this connection, and provide actionable tips to help you manage stress and support your goals.
How does stress cause weight gain?
1. Hormonal changes
One of the primary ways stress can cause weight gain is through hormonal changes in the body. When we are stressed, our body releases a hormone called cortisol, which plays a critical role in the body’s fight-or-flight response. The connection between cortisol and weight gain is significant.
Cortisol is necessary for survival in stressful situations, but when levels remain elevated over time, it can cause your body to enter a state where it burns fewer calories and stores more fat, especially in the abdominal area. This slowing of metabolism can make it harder to lose weight or even maintain a healthy weight, despite efforts to eat well and exercise.
2. Emotional eating and cravings
Stress doesn’t just alter how our body processes fat—it also changes how we eat. Ever found yourself reaching for junk food when you’re overwhelmed? This isn’t just a habit; it’s a biological response driven by stress.
There will be an increase in cravings for high-calorie, sugary foods. These foods are comforting in the moment and become a coping mechanism but over time, they can lead to overeating and weight gain. From a psychological perspective, stress may cause people to indulge in emotional eating, where they consume foods high in sugar, fat, and calories. This stress-induced eating can lead to excessive calorie intake and, in some cases, feelings of guilt or shame, which only reinforce the cycle. Breaking this cycle is key to preventing stress-related weight gain.
3. Disrupted sleep patterns

Stress can also cause weight gain by disrupting sleep patterns, with many individuals experiencing insomnia or poor sleep quality due to heightened alertness. Chronic stress keeps the nervous system in a heightened state, leading to restless nights. This makes it harder to relax and achieve restorative sleep.
Poor sleep has been linked to several factors that contribute to weight gain. For example, sleep deprivation increases the production of ghrelin, the hunger hormone, while reducing leptin, the hormone that signals fullness. This imbalance leads to heightened hunger and cravings, making it more challenging to avoid overeating.
4. Reduced physical activity
Regular exercise plays a crucial role in maintaining a healthy weight, as it helps to regulate metabolism, burn calories, and promote overall physical health. However, stress may cause individuals to feel fatigued or mentally drained. This makes it harder for them to find the energy or motivation to exercise, causing them to adopt a more sedentary lifestyle. This, coupled with increased stress levels, can cause even more weight gain.
How to manage stress for a healthier weight

It’s clear that managing stress is as important as exercise and a healthy diet when it comes to weight management. Here are some strategies to help you mitigate the impact of stress on metabolism and weight gain:
- Practice stress-relief techniques – Try meditation, deep breathing exercises, or yoga to regulate stress levels and balance hormones.
- Find healthy coping mechanisms – Instead of turning to food for comfort, try hobbies, journaling, or spending time with loved ones.
- Prioritise quality sleep – Aim for seven to nine hours of sleep per night to regulate hunger hormones to support healthy metabolism.
- Stay active – Keep moving. Even low-impact activities like walking, stretching, or swimming can reduce cortisol levels and boost overall well-being.
- Eat mindfully – Focus on nutrient-dense, whole foods to stabilise blood sugar levels and prevent stress-related cravings.
Taking a holistic approach to weight management
However, despite our best efforts, managing stress and weight can be challenging due to the responsibilities we carry in our everyday lives. If you’re struggling to achieve your desired results, seeking support from professionals who can offer guidance may be helpful. A tailored weight loss programme, for example, can provide targeted strategies and support to help you overcome obstacles and reach your goals.
Additionally, non-invasive fat removal treatments such as cryolipolysis can address stubborn fat that resists diet and exercise. While these treatments focus on reducing localised fat deposits and do not affect overall body weight, they can improve body contours and appearance. A weight loss doctor might incorporate fat reduction treatments alongside a weight management plan for a more comprehensive approach.
