Ever wondered why you always crave a cheeky late-night kebab after a heavy night of drinking?
Well, scientists might finally have come up with an answer.
Australian researchers say alcohol ups levels of a hormone in your body that makes you crave protein.
Most of the almost 4,000 drinkers studied chose to fill their desire with lean meats, fish and nuts.
But a third instead opted for ‘protein decoys’, which could include the greasy kebab and chips that’s become a staple of a modern British night out.
Crisps, sausage rolls and garlic bread are other examples of the calorific snacks.
The foods all give the protein-like umami taste but are actually low in protein, hence the nickname.
University of Sydney researchers have now urged all drinkers to stick to lean meats, chicken, fish and legumes when they inevitably get hungry.
The so called ‘aperitif effect’ which causes people who drink alcohol to crave proteins could be leading weight gain by tricking people into eating savoury snacks
What is the perfect pre-drinking snack according to scientists
Australian scientists say alcohol increases cravings for proteins which can lead drinkers to make some unhealthy choices.
To beat the cravings they recommended drinkers instead have a pre-drink snack.
Their suggestions include:
- A 40g serving of cheese
- Unsalted nuts
- Vegetable sticks with a tzatziki or hummus dip
Lead author Dr Amanda Grech said: ‘Avoid the urge to snack on low-protein, savoury snack foods.
‘This will ensure your protein appetite is satisfied without over-consuming energy, leading to weight gain.’
Suggested snacks included a 40g serving of cheese, unsalted nuts, chickpeas, and vegetable sticks with a tzatziki or hummus dip made with fresh ingredients.
She added: ‘Above all, be sure to stick within the guidelines for alcohol intake, which poses health risks other than weight gain and obesity.’
UK health chiefs advise Britons to drink no more than 14 units per week — around six pints of beer or 10 small glasses of wine.
Drinking too much alcohol for many years can raise the risk of high blood pressure, strokes, liver disease and some cancers, as well as dementia.
The study, to be presented at the International Congress on Obesity in Melbourne, used data on 9,341 Australian adults who took part in a 24-hour nutrition survey that tracked their drinking habits and dietary preferences in that day.
Of the adults taking part, 40 per cent reported consuming alcohol that day.
Unsurprisingly, the analysis showed people who had consumed alcohol consumed more savoury foods than those who didn’t drink.
But what was surprising is that some drinkers ended up consuming far more calories than others.
The NHS recommends that adults drink no more than 14 units each week — that’s 14 single shots of spirit or six pints of beer or a bottle and a half of wine
More than 42million adults in the UK will be overweight or obese by 2040, according to projections by Cancer Research UK
Two-thirds of drinkers chose foods high in proteins but low in carbohydrate and fat, like lean meats, poultry, seafood, nuts, and beans.
These drinkers consumed 1,749 calories on average, roughly 577 calories below the amount needed for an adult to maintain their weight. This included calories from the alcohol.
Drinkers who opted for ‘protein decoys’ consumed 3,051 calories on average, 813 more than their daily requirement.
Dr Grech added: ‘It’s known alcohol increases appetite, particularly for savoury food, a phenomenon that’s known as the “apertif effect”.
‘Recent research has shown levels of FGF-21, a hormone that increases protein appetite and suppresses appetite for sweetness, increase after alcohol is consumed.
‘It’s also known that protein has a satiating effect.’
How much alcohol is too much?
To keep health risks from alcohol to a low level, the NHS advises men and women not to regularly drink more than 14 units a week.
A unit of alcohol is 8g or 10ml of pure alcohol, which is about:
- half a pint of lower to normal-strength lager/beer/cider (ABV 3.6%)
- a single small shot measure (25ml) of spirits (25ml, ABV 40%)
A small glass (125ml, ABV 12%) of wine contains about 1.5 units of alcohol.
But the NHS warns the risk to your health is increased by drinking any amount of alcohol on a regular basis.
Short-term risks include injury, violent behaviour and alcohol poisoning.
Long-term risks include heart and liver disease, strokes, as well as liver, bowel, moth and breast cancer.
People who drink as much as 14 units a week are advised to spread it evenly over three or more days, rather than binge drinking.
Women who are pregnant or trying to become pregnant are advised not to drink to reduce risks for the baby.
