What are low-calorie alcoholic drinks in a can?

Low-calorie alcoholic drinks are alcoholic beverages that are low in calories (the energy in food and drink). The number of calories everyone needs per day depends on a few factors, including age, height, weight, and activity levels. If you go above your maintenance level (the number you need to maintain your weight), you'll gain weight. If you go below it by eating fewer calories or burning more, you'll lose weight. 

If you are trying to get into a calorie deficit to lose weight and drinking is a big part of your social life, you may not want to cut alcohol out completely - and there's no need to either. “If you’re looking to reduce your calorie intake whilst enjoying alcohol over the summer, I’d recommend opting for low-calorie vodka and other light spirits with diet mixers over sugary alcopops, ciders, and cocktails," says Richie Howey, a certified personal trainer and lifestyle coach. "It’s all about making smart choices that serve you and your weight loss goals." 

Low-calorie alcoholic drinks in a can are also helpful here, as some of the most common ones include spritzers, low-calorie cocktails, and seltzers - flavoured sparkling water combined with a type of spirit (usually vodka). 

What's the best low-calorie alcoholic drink in a can for weight loss?

When we look exclusively at calories per serving, a simple mixer and spirit or low-calorie beer will ultimately be the best low-calorie non-alcoholic drink in a can. This includes options like gin and diet tonic, tequila and diet tonic, rum and diet cola, and beers like Camen Hells and Skinny IPA. 

These options will have less sugar in the recipe than even some of the low calorie cocktail options, simply because cocktails require more ingredients that tend to sit on the sweeter end of the taste spectrum. Sweeter ingredients tend to contain sugar, which is higher in calories. 

How does alcohol impact weight loss?

Drinking alcohol can make it harder to lose weight in several ways. Firstly, you can 'drink your calories' without realising it, as alcohol is one of the most calorie-rich substances, with three calories per gram of liquor. Drinking can easily take you out of a calorie deficit, which is essential for sustainable weight loss. 

"It all comes down to calories," PT Richie Howey confirms. "For example, the difference between choosing a diet mixer over a full-fat Coke can be 500 to 1000 calories through a night out." This can be the difference between sticking to your deficit and not losing weight at all, especially if you drink regularly. 

If you are looking to lose weight, it's worth considering cutting down on alcohol - or even giving alcohol up for good, at least during the weight-loss process.

Just as many great alcoholic drinks come in a can, you'll find some of the best low-calorie non-alcoholic drinks in a can just as delicious.

Drinking also doesn't only inhibit our ability to lose weight by putting more calories in the body though. It's what we do when we're hungover that makes a difference too. Even if you're opting for the best low-calorie alcoholic drinks in a can, how many you drink will matter. 

“As alcohol causes dehydration, hunger levels spike, and people end up bingeing, mainly because it’s difficult to control cravings when you’re intoxicated. Think about all the kebabs, pizzas, and cheesy chips you’ve indulged in over the years. They’re all high-fat meals that are the worst thing you could possibly eat when you're out.”

Consider the day after the night before, Howey says. "You hardly move at all. That means low-calorie expenditure, followed by another takeaway on the night as you’re bound to have the munchies. So, really, you’ll have consumed a double dose of calories.”

While a weight loss goal shouldn't prevent you from enjoying yourself, and you can enjoy alcohol in moderation with low-calorie alternatives if you're concerned about your daily calorie count, there's no doubt that alcohol definitely makes a difference.

“Fat burning is put on the back burner when you’ve had a few because your body is going to prioritise getting rid of the toxin (alcohol) before it metabolizes fat, so instead it just stores fat," Howey says.
