Overeating is a very normal human behaviour. Even children — our most intuitive eaters — overeat from time to time.
What does overeating feel like?
Overeating essentially means we have eaten when we are not hungry, or eaten past the first signs of fullness — more than our body needs at that point in time. But to understand fullness, we first need to understand hunger.
Our body signals the need for food through one or a combination of physical sensations and thoughts. How hunger feels can vary greatly from person to person. For some, it creeps up slowly; for others it can feel very sudden and urgent. This depends on the time of day, how busy you are, and how tuned in you generally are to your body. Hunger can feel like an emptiness in the stomach, low energy, tiredness, a change in mood, or a pain or nausea in the stomach — and quite often it leads to thinking more about food. This is your body’s way of telling you to eat. The key is knowing what your own personal hunger signals are, so you can recognise them as they develop.
Fullness is the other side of the eating spectrum and can be equally difficult to recognise if we aren’t paying attention. Fullness is when hunger fades, the tastiness of food starts to decrease, and we feel a gentle stretch or pressure in the stomach. It becomes harder to notice when we are distracted (such as being on a phone or watching TV), eating quickly, or eating when very hungry.
Is overeating normal?
There are several normal and reasonable situations where we eat without being physically hungry:
- Time constraints. Designated meal breaks at work or school mean it makes sense to eat even if you haven’t reached your usual level of hunger — it may be several hours before the next opportunity.
- Changing routines. Shift work can disrupt your body’s normal rhythms, including hunger. Eating according to a regular schedule or in line with shift patterns can help the body adjust.
- Eating soon after waking. Many people don’t feel hungry in the morning — due to eating late the night before, starting the day with coffee, or simply being short on time. Eating something anyway can help sustain energy through the morning.
- Taste and enjoyment. Great-tasting food can bring real comfort and joy even when we are not hungry — and this is completely normal. Food can also be one of the ways we cope with difficult emotions. While it can be effective in the short term, relying on it as your main coping mechanism can have negative impacts on both physical and mental health over time. Developing a wider range of coping strategies is a healthier long-term approach.
What are cravings and why do they happen?
Cravings can feel like there is something wrong with us, but they are more to do with the body just doing its job. Some of the reasons we experience food cravings include:
- Skipping meals or eating irregularly causes swings in blood sugar levels. The body constantly monitors these levels, and when blood sugar drops, it triggers the release of ghrelin, the hunger hormone. If you don’t eat, ghrelin builds and creates a craving for high-energy, high-reward foods, those most likely to raise blood sugar quickly.
- Poor sleep increases ghrelin while also reducing leptin, your satiety hormone, a double blow that leaves you with a higher appetite that is harder to satisfy. Combine this with skipping breakfast and you have the perfect conditions for strong cravings, particularly for sweet foods.
- Chronic stress elevates cortisol, which increases appetite and drives cravings specifically for high-fat, high-sugar foods. The drive for comfort food is a biological response to stress, not a character flaw. Research also suggests that under chronic stress, excess energy is more likely to be stored as abdominal fat rather than distributed evenly around the body.
- Dietary restriction itself drives cravings. Labelling foods as ‘off-limits’ increases their desirability, a phenomenon known as the ‘what the hell effect,’ where people who consciously restrict their intake are more likely to overeat when a slip occurs (“what the hell, I’ve already broken my diet”). Research has found that even short-term calorie restriction activates the brain’s reward-seeking pathways, making palatable food appear even more desirable.
Hunger vs Cravings – How to tell the difference.
Being able to tell the difference between hunger and a craving can tell you a lot about what you actually need in that moment.
Physical hunger tends to develop gradually. In the early stages, it’s a good time to choose foods that are balanced in nutrients and will sustain you until your next meal or snack.
If hunger appears suddenly, it may be a later-stage hunger with lower blood sugar, presenting as a strong preference for particular foods or flavours. This is also a good moment to consider other causes — emotions, tiredness, or environmental triggers. If it might be a craving, try incorporating the desired food into your meal, or enjoy a small amount afterwards as mindfully as you can. Deprivation rarely helps.
6 practical strategies to reduce cravings
1. Don’t skip meals. Regular meal timing reduces rebound hunger and craving intensity later in the day.
2. Prioritise protein at meals. Protein increases satiety hormones, reduces ghrelin, and is the most filling macronutrient gram for gram.
3. Build a predictable eating routine. Consistent meal timing supports better appetite regulation and reduces impulsive eating.
4. Keep nourishing options accessible. Simple environmental changes, (e.g. keeping fruit visible, pre-portioning snacks) make the easier choice the obvious one.
5. Protect your sleep. Even partial sleep restriction meaningfully increases next-day appetite and cravings. Seven to nine hours is the evidence-based target.
6. Name the trigger, not the food. Identifying stress, boredom, or fatigue as the driver gives you agency, without requiring restriction.
Small habit changes that reduce cravings long-term
Habit change needs time and consistency to become automatic. The old myth that it takes 21 days isn’t supported by evidence, the reality is it’s different for everyone.
Some people love the stability of routine, which means changing well-established habits requires more patience and resilience when slip-ups happen. Others find introducing new behaviours less daunting but struggle with consistency and benefit from external supports like alarms, reminders, or tracking.
Starting with just one change is achievable for most people and far less overwhelming than attempting six at once. That first change also tends to build the confidence and motivation to tackle the next, so it often gets easier as you go.
When to seek support
Occasional overeating is normal. Frequent, distressing, or out-of-control eating, especially when followed by guilt, shame, or compensatory restriction, may be a sign that it’s worth speaking with your GP about the support available to help you develop a healthier and happier relationship with food.
Conclusion
Cravings are normal, manageable and largely biological. Awareness is the first practical step. Small routine changes (not restriction) are the evidenced-based path forward.
