Beer and spirits top the list of alcoholic drinks most likely to expand your waistline, according to a study published in Obesity Science & Practice. Analyzing 1,869 adults aged 40 to 80, researcher Brittany A. Larsen and her team found that not all alcohol affects belly fat equally — and the type of drink matters far more than most people assume.
Not all drinks are created equal when it comes to abdominal fat. That's the central finding of a study that cuts through the conventional wisdom of "alcohol makes you fat" and asks a more precise question: which alcohol, exactly?
The answer has real implications — not just for anyone watching their waistline, but for the doctors and dietitians who advise patients every day.
Beer and spirits are the worst offenders for visceral fat
The study is unambiguous on this point. Both beer and spirits are associated with an increase in visceral fat, the deep abdominal fat that accumulates around internal organs. This isn't the subcutaneous fat you can pinch — visceral fat is metabolically active and linked to a range of health risks, making it a legitimate concern for adults in midlife and beyond.
Why beer earns its "beer belly" reputation
The association between beer and belly fat is well-established in popular culture, and this research backs it up scientifically. Beer is calorie-dense, often consumed in large quantities, and tends to be paired with high-calorie foods. But beyond the simple calorie equation, the study confirms that beer specifically promotes the accumulation of fat in the abdominal region, reinforcing what many have long suspected.
Spirits: a surprising entry on the list
Spirits might seem like the "lighter" option — no carbs, no bubbles — but the data tells a different story. Spirits also drive visceral fat accumulation, placing them firmly alongside beer as drinks to moderate if abdominal fat is a concern. This finding may surprise those who opt for a whisky or vodka thinking they're making a smarter choice.
Both beer and spirits are linked to increased visceral fat in adults aged 40 to 80, regardless of total alcohol quantity consumed.
Red wine and white wine tell a very different story
Here's where the study becomes genuinely surprising. Red wine doesn't just avoid promoting belly fat — it appears to actively work against it. The research points to an anti-inflammatory effect and an ability to inhibit the storage of abdominal fat. Compounds in red wine, particularly polyphenols, are likely responsible for this protective mechanism, though the study stops short of recommending red wine as a health strategy.
White wine occupies its own distinct category. It shows no meaningful impact on body fat, which already sets it apart from beer and spirits. But there's an additional finding worth noting: white wine may carry a potential benefit for bone health in older adults. This doesn't make it a supplement, but it does suggest the effects of different alcoholic beverages are far more nuanced than a simple "alcohol equals weight gain" narrative.
Champagne, meanwhile, is grouped alongside white wine in terms of its minimal impact on abdominal fat accumulation — a detail that may comfort those who enjoy a glass on occasion without wanting to sabotage their efforts to get a flatter belly.
- Red wine: anti-inflammatory, inhibits abdominal fat storage
- White wine: neutral impact on body fat, possible bone health benefit
- Champagne: minimal impact on visceral fat
- Beer: directly linked to visceral fat accumulation
- Spirits: also associated with increased abdominal fat
What doctors and dietitians should be asking their patients
One of the more practical takeaways from Larsen's research is directed squarely at healthcare professionals. The study argues that physicians and dietitians should shift the conversation around alcohol. Rather than focusing exclusively on total quantity consumed, they should be asking older adults about the type of alcohol they drink.
This distinction matters because two patients consuming the same number of drinks per week could have very different outcomes for abdominal fat depending on whether those drinks are beer or red wine. For adults between 40 and 80 — already navigating hormonal changes, slower metabolisms, and shifting fat distribution — this kind of precision could make a meaningful difference in how dietary advice is tailored.
The recommendation from the study is clear: reduce or eliminate alcoholic beverages, or consume them with moderation. But when consumption does occur, the type of drink is a variable that deserves attention. This aligns with broader research suggesting that fighting cravings and managing weight requires a more individualized, context-aware approach than blanket restrictions.
Alcohol is one piece of a larger puzzle
The study is careful not to present alcohol as the sole driver of abdominal weight gain. Brittany A. Larsen and her team acknowledge that diet, sleep quality, physical inactivity, and genetic predispositions all contribute to the accumulation of belly fat. Alcohol is a significant factor, but it operates within a broader lifestyle context.
This is worth keeping in mind for anyone who has already addressed the more obvious contributors. If sleep is poor, sedentary habits dominate the day, or diet is consistently high in processed foods, switching from beer to red wine won't undo those factors. Research consistently shows that belly fat responds to a combination of approaches, and alcohol type is just one lever among many.
The study was conducted on 1,869 adults between the ages of 40 and 80 and published in the peer-reviewed journal Obesity Science & Practice. Lead researcher Brittany A. Larsen directed the analysis comparing the abdominal fat impact of beer, cider, red wine, white wine, champagne, and spirits.
What the research ultimately delivers is a more granular understanding of how alcohol interacts with the body. For adults already attentive to their health — and perhaps already adopting daily habits to support weight management — knowing that a glass of red wine and a pint of beer are not metabolically equivalent is genuinely useful information. The type of drink on the table turns out to matter quite a bit.
