We’ve all been there. It’s late in the evening, dinner’s over, and we should be winding down for bed – but we start feeling peckish. Should we head to the kitchen and grab something to eat or tough it out until morning?
Most of us have heard that you shouldn’t eat too close to bedtime, and there’s plenty of research to suggest that doing so regularly could have some adverse effects on our weight and sleep.
But, the occasional healthy evening (or even midnight) snack is unlikely to make much difference to your health. Plus, if you find yourself feeling hungry before bed, your body might be hinting that you haven’t eaten enough that day – so there’s no need to suffer until breakfast.
With this in mind, we’ve pulled together a list of eight healthy foods that’ll hopefully keep you satisfied until morning, and may even help you sleep better.
The science behind snacking in the evening
Late-night snacking has long been scrutinised, but why is that?
Some studies suggest that eating within an eight to 12 hour window during the day can be beneficial for preventing conditions like heart disease and type 2 diabetes by helping to regulate our body clock.
There’s also discussion about the impact that eating late in the evening can have on our sleep and weight.
We’ll look at what research says in more detail below…
The impact of late-night snacking on weight
There’s mounting evidence to suggest that regularly eating late in the evening or at night can lead to weight gain.
For example, this study looked into the effects of two different meal patterns. The first pattern involved eating meals earlier in the day, with the last meal eaten approximately six and a half hours before bed. In the second, participants ate their meals later on, with dinner being eaten approximately two and a half hours before bed.
The results found that the second pattern led to increased feelings of hunger the following day, as well as a reduction in the number of calories burned. This study also found similar results.
The reason for this isn’t entirely clear, though some experts say it’s to do with how our circadian rhythm affects metabolism, nutrient absorption, and insulin sensitivity.
The impact of late-night snacking on sleep
Eating late at night has also been linked to disrupted sleep.
This study found that the more people ate in the evening – especially foods with a high fat content – the worse their sleep was. Specifically, it revealed that they spent less time in REM sleep (one of the most restorative stages of the sleep cycle) and had more difficulty falling and/or staying asleep.
Plus, if you’re prone to experiencing acid reflux, the combination of eating before bed and lying down can trigger heartburn, which can disrupt sleep.
The verdict – is late-night snacking bad for us?
Before we move on to ideas for healthy evening snacks, it’s worth pointing out that the occasional late-night snack is unlikely to have any major consequences for your health. So, while being conscious of these findings can be useful, you don’t necessarily need to start making big changes to your eating habits.
Some health experts even suggest that eating certain foods before bed is perfectly healthy and can actually improve sleep and aid weight loss.
That said, it’s generally agreed that certain foods are best avoided before bed. This includes spicy foods, caffeine, foods with high amounts of sugar, and processed carbs as these may keep you up and are of little nutritional value.
Instead, it’s best to reach for something nutrient-dense, low in calories, high in protein and/or fibre, and minimally processed (ideally a whole food), like the suggestions below…
8 healthy and filling evening snacks
1. Pistachios
A handful of pistachios (30 kernels) adds up to around 100 calories, and the high fibre and protein content of this little green nut means it can keep you fuller for longer.
Pistachios are particularly good choices for late-night snacking because of the amount of melatonin they contain. Melatonin is a hormone that helps to control and regulate sleep patterns – and eating it before bed can help us to fall asleep faster and stay asleep for longer.
Nuts in general are known for their high melatonin levels, and pistachios contain the most of all. Plus, prising open the shells before bed can be tiring in itself!
2. Cottage cheese
Whole foods that are high in protein and low in carbohydrates make excellent evening snacks. This is because protein takes longer than carbohydrates to digest, meaning it can keep you feeling satisfied until breakfast.
This makes cottage cheese a great before-bed snack. Low-fat varieties made from 1% milk can contain only 163 calories per cup, while still packing a whopping 28g of protein – which is over half of the recommended daily amount.
Research also suggests that eating 30g of protein half an hour before bed could boost muscle growth and metabolic rate throughout the night – meaning that it may even contribute to how efficiently you burn calories while at rest.
Cottage cheese can be a little plain on its own, so why not combine it with a sprinkling of berries, a sliced banana, and/or nuts? This article from Simple Nourished Living has more suggestions on creative ways to eat it.
3. Kiwis
Another food that’s low in calories and may help us sleep better is kiwi. This study found that people who ate kiwi one hour before bed for a month experienced a 35% reduction in the time it took for them to fall asleep.
They also reported better sleep quality. The reason for this is unclear, but it may be linked to the high serotonin levels in kiwis. Serotonin is a neurotransmitter that’s essential for regulating sleep.
An average-sized kiwi only contains around 60 calories. It also delivers 15% of our daily intake of fibre and twice as much vitamin C as an orange.
4. Porridge
Porridge is a tried and tested breakfast choice – but did you know that it makes a delicious evening snack too?
Packed full of fibre, oats will hopefully keep you full until morning and, like nuts, they’re a good source of melatonin. But this isn’t their only sleep-promoting ingredient. Oats also contain the amino acid tryptophan, which is converted to serotonin when it reaches the brain.
A small bowl of porridge containing 25g of rolled oats and 150ml of skimmed milk contains around 150 calories. If this sounds a bit plain, try stirring some cinnamon in for a warm and comforting pre-bed snack, or a dash of raw honey, which is thought to have sleep-promoting properties of its own.
5. Greek yoghurt
In the evenings, many of us find ourselves turning to sweet things like desserts or biscuits. However, high-sugar foods are some of the worst things we can eat before bed – not only because they’re high in calories and won’t keep us full for long, but because sugar may disturb sleep.
For something that feels like a treat, yet is low in calories and full of nutrients, why not turn to Greek yoghurt? Greek yoghurt is high in protein and calcium, which enables the brain to produce melatonin.
If simple Greek yoghurt seems a bit boring, why not try adding a few nuts or berries? This article from Ochsner Health has a few helpful suggestions for tasty and creative ways to enjoy it, including my personal favourite – freezing it into creamy ice lollies.
6. Eggs
This eggcellent option may be a breakfast favourite but it also makes for a quick, easy, and nutritious evening snack.
Two average-sized eggs contain approximately 156 calories, 12g of protein, and a range of sleep-inducing ingredients – such as tryptophan, melatonin, and vitamin D.
You can enjoy your evening eggs poached, fried, or however you like them. However, keeping a few hard-boiled ones in the fridge is a handy, fuss-free way to satisfy hunger pangs as soon as they arrive. Why not give one of these quick and easy egg recipes a try?
7. Bananas
There’s a reason why bananas are a tried and tested healthy snack. They’re low in calories and are great for keeping hunger at bay. This has a lot to do with the fact that they’re packed full of pectin; a soluble fibre found in fruits and vegetables that increases feelings of fullness.
Plus, bananas have relatively high levels of tryptophan and magnesium which help to promote sleep by increasing the production of melatonin. Magnesium also decreases cortisol levels. Cortisol is known as ‘the stress hormone’ and it can keep you awake.
Unlike sugary, fast-digesting carbohydrates found in snacks like cakes and biscuits, higher-fibre carb options like bananas are slower to digest. They also won’t cause sharp spikes in your blood sugar levels – something that can make it more difficult to fall asleep.
If you’re in the mood for something a little more interesting, some people enjoy pairing banana with almond butter. This isn’t only tasty, but it’ll give you an extra helping of magnesium and melatonin.
8. Oily fish
Oily fish – like mackerel, tuna, salmon, and sardines – are superfoods and will serve you well when you feel hungry just before bed. They’re high in protein and rich in lots of key nutrients – particularly vitamin D and omega-3 fatty acids, which are understood to help with sleep.
These tuna salad cucumber cups are a tasty way to enjoy fatty fish late at night, without worrying about eating a load of carbs. Mackerel on whole wheat toast is another popular option.
