What Your Cravings Are Really Telling You
Summer holidays are in full swing, and as people unwind and enjoy the break, unhealthy eating habits often creep in, with studies showing that over a third admit to ditching their healthy meals when the sun comes out.
While occasional indulgence is completely normal, when does it become a serious health concern?
With 90% of people experiencing food cravings at some point, ZAVA, with the expert advice of Doctor Crystal Wyllie, breaks down the most common causes of cravings beyond hunger, the smartest strategies to overcome them, and the red flags that could mean it’s time to seek support.

Why is junk food so irresistible? Here’s the truth: junk food is designed to be addictive. High-sugar, high-fat, and full of flavour and texture, these foods light up the pleasure centre in our brain, triggering feel-good chemicals like dopamine and serotonin. It’s no wonder we reach for them when we are stressed or tired.
While occasional indulgence is perfectly normal, frequent junk food cravings can come with real health consequences. That overwhelming urge for chocolate, crisps, or a midnight snack often has little to do with true hunger. In fact, most cravings are your body, or your brain, trying to tell you something. But what exactly?
The most common causes of food cravings:
Emotions and stress
Cravings often start in the brain, not the stomach. Studies show nearly 1 in 3 people engage in emotional eating. Comfort foods, especially those high in sugar and refined carbs, offer a temporary serotonin lift, helping you feel better in the moment. But when stress hits, cortisol spikes, increasing appetite and impulsive eating.
Hormones and menstrual cycles
Hormonal changes during menstruation, pregnancy or menopause can trigger intense cravings, especially for sweet or salty foods. In particular, the drop in estrogen and rise in progesterone during the luteal phase (the week before your period) are known to increase appetite.
Lifestyle factors
Lack of sleep, stress, skipping meals or falling into habitual eating patterns –such as always grabbing a treat with your tea– can all fuel cravings. Ultra-processed foods are literally engineered to keep you coming back for more.
Deficiencies and dehydration
Cravings can also be clues. Your body may be low on magnesium, zinc, sodium, or might just need water. Dehydration can mimic hunger signals. Skipping meals or blood sugar dips can also spark intense cravings, especially for carbs and sugar.
The 6 smartest strategies to manage food cravings:
ZAVA’s new Cravings Calculator helps uncover the reasons behind your eating habits. But regardless of what’s driving your cravings, Doctor Crystal Wyllie, ZAVA Online Doctor, shares the most effective ways to manage them and take back control:
- Find the root cause
Cravings can be physical, emotional or habitual, or a combination of all three. Identifying your triggers is the key to changing your behaviour.
“Noticing when and why cravings strike can help you respond more intentionally. Is it boredom? Hormones? A stressful day? Awareness is the first step to change. Once you’ve identified the underlying reason, be it emotional eating or a lack of self care, you can then tackle your cravings head on and make some long-term changes”
- Crave smarter, not harder
Going cold turkey often backfires. Instead, satisfy cravings with smarter swaps such as fruit, yoghurt, nuts, or protein-based snacks. Choose foods you actually enjoy so you don’t feel deprived.
“It’s better to satisfy a craving in a controlled way than ignore it and end up bingeing later”
- Eat balanced meals
Skipping meals or relying on snacks throughout the day can trigger cravings. Aim for meals rich in protein, fibre and healthy fats to help regulate blood sugar, keeping you full and focused.
“A well-balanced plate helps reduce cravings by keeping you full and energised throughout the day. Eating a colourful, nutrient-rich diet can also help correct underlying deficiencies that may be driving those cravings”
- Support mental wellbeing
Stress and poor sleep affect appetite hormones. Mindfulness techniques, meditation or even a brisk walk or, simply talking to a friend, can help curb emotional eating.
“Taking a moment to pause and ask whether a craving is emotional or physical can benefit both your body and your mental health”
- Stay hydrated
Your body can mistake thirst for hunger. Try drinking a glass of water, waiting 10-15 minutes and reassessing the craving.
“Hydration is often overlooked, but it’s essential, especially when it comes to managing sugar cravings”
- Recognise the right time to seek support
If your cravings feel constant, overwhelming, or difficult to control, don’t hesitate to seek support. While only 1 in 4 people with binge eating disorders currently receive treatment, speaking to a GP, nutritionist, or therapist can make a meaningful difference. If you’re unsure whether it’s time to ask for help, here are some signs your cravings might be more than just the occasional urge:
Weight fluctuations: Frequent overeating in response to cravings can lead to weight gain and make weight loss more difficult.
Low mood: Indulging too often can lead to guilt or shame. In ZAVA’s recent study, 48% of people reported low self-esteem linked to their weight.
Health problems: Craving-driven diets high in sugar or refined carbs can weaken immunity, cause mood swings, and leave your body undernourished.
