Beer and spirits top the list of alcoholic drinks most likely to expand your waistline, according to a study published in Obesity Science & Practice. Researchers analyzed 1,869 adults aged 40 to 80 and found that not all alcohol affects belly fat the same way — the type of drink matters as much as the amount.
Most people know that alcohol and weight gain go hand in hand. But the conversation usually stops there, lumping every glass of wine, pint of beer, and shot of whiskey into the same category. A study led by researcher Brittany A. Larsen suggests that approach misses something significant.
The findings are clear: what you drink shapes where fat accumulates in your body, and the belly is the primary battleground.
Beer is the biggest driver of visceral fat accumulation
Visceral fat — the deep abdominal fat that surrounds internal organs — is not just a cosmetic concern. It's the kind of fat most directly linked to metabolic disorders, and beer appears to feed it more aggressively than other alcoholic beverages.
The study found that regular beer consumption correlates with a notable increase in visceral fat among adults in the 40 to 80 age range. And beer isn't alone. Spirits — whiskey, vodka, gin, rum and their variants — produce a similar effect on abdominal fat storage.
Why beer and spirits hit the belly hardest
The mechanism isn't mysterious. Beer combines alcohol with a significant carbohydrate load, creating a double stimulus for fat storage. Spirits, while lower in carbs, deliver concentrated doses of alcohol that the liver prioritizes over fat metabolism. When the liver is busy processing alcohol, dietary fat gets stored rather than burned. The belly, with its high density of fat-storing cells, tends to absorb the overflow.
Visceral fat — the kind that builds up around the abdomen — is associated with a higher risk of cardiovascular disease and type 2 diabetes. It is not visible from the outside and cannot be measured by weight alone.
Red wine and white wine behave differently from other alcoholic drinks
Here's where the study gets more nuanced. Not every glass adds to the belly. Red wine emerged as the most favorable option, showing an anti-inflammatory effect and a demonstrated ability to inhibit abdominal fat storage. The polyphenols in red wine — particularly resveratrol — are thought to play a role in this protective mechanism, though the study doesn't isolate a single cause.
White wine tells a different story, but not a negative one. Researchers found no significant impact on body fat from white wine consumption. And in older adults specifically, white wine showed a potential benefit for bone health, making it a noteworthy finding for the post-50 demographic who already face increased osteoporosis risk.
Champagne: a gap in the data
Champagne was included in the analysis, though the study's findings on sparkling wine were less definitive than those for still wines, beer, or spirits. What the data does confirm is that champagne falls outside the beer-and-spirits category when it comes to visceral fat impact.
- Red wine: anti-inflammatory properties, inhibits abdominal fat storage
- White wine: neutral impact on body fat, possible bone health benefit in older adults
- Beer: significant increase in visceral fat
- Spirits: similar visceral fat accumulation effect
What doctors and dietitians should ask — and why it changes everything
One of the study's most practical conclusions targets medical professionals directly. Researchers recommend that doctors and dietitians shift their questioning when speaking with older adult patients. Rather than focusing exclusively on total alcohol consumption — how much, how often — they should ask about the type of alcohol consumed.
This is a meaningful shift. A patient who drinks two glasses of red wine per evening is in a very different metabolic situation than one who drinks two beers or two spirits. The quantity looks identical on paper. The effect on visceral fat does not.
Concrètement, this means standard dietary intake forms and clinical conversations may be overlooking a key variable. If you're working with a nutritionist on reducing belly fat, the type of alcohol in your routine deserves a specific conversation — not just a general "cut back on alcohol" recommendation.
Alcohol is one piece of a larger puzzle
The study is careful to frame alcohol within a broader context of weight gain factors. Sedentary behavior, poor sleep, genetic predispositions, and overall diet all contribute to abdominal fat accumulation. Alcohol is a significant variable, but not the only one. Researchers working on behavioral approaches to cravings and appetite have shown that addressing multiple lifestyle factors simultaneously tends to produce better results than targeting a single habit in isolation.

The recommendation is moderation — but type matters too
The study's authors do not give a green light to unlimited red wine. The overall recommendation remains consistent with standard health guidance: abstain from alcohol or consume it in moderation. But the research adds a layer that wasn't there before. If you are going to drink, the choice of beverage has measurable consequences for abdominal fat.
For adults over 40, this is particularly relevant. Visceral fat tends to accumulate more readily with age, especially as hormonal changes alter fat distribution patterns. Women entering perimenopause and menopause, for instance, often notice a shift in where their body stores fat — and alcohol choices during this window can amplify or moderate that shift. Maintaining a healthy body composition after 50 involves attention to multiple dietary factors. Some nutrient-dense foods have shown real effects on belly fat, and the same logic applies to what you drink.
But the bottom line from Brittany A. Larsen's research is straightforward: if belly fat is a concern, beer and spirits are the drinks most likely to make it worse. And that distinction, backed by data from nearly 2,000 adults, is worth factoring into your next drink order.
