The foods most likely to cause belly fat, according to science

19 December 2025

Let’s be honest: almost nobody wakes up in the morning excited at the idea of belly fat. Yet, while society’s beauty standards push us to wage war on our waists, the reality is much less dramatic. Belly fat is a natural phenomenon and, if present in reasonable amounts, it’s not unhealthy. The real trouble isn’t having some—it’s having much too much.

When Belly Fat Becomes a Problem

We should not fear every inch of padding around the midriff. It’s when belly fat grows excessive that it actually poses health dangers. Certain foods, like avocados, can help reduce visceral fat (that’s the technical term for fat deep inside your abdomen). But on the flip side, there are plenty of foods that nudge the scales the other way. Curious which ones top the scientific charts? Keep reading—no six-pack required.

The Usual Suspect: Added Sugar

If there’s a food villain worthy of a starring role, it’s excess sugar. Official bodies—including the World Health Organization—are crystal clear about it: to stay in good health, don’t consume too much sugar. Specifically, the recommended daily maximum is 25 grams, which roughly equals six teaspoons. (As anyone who’s baked cookies knows, that’s not a lot.)

Here’s where the trap lies: foods and drinks rich in added sugars send your daily intake rocketing. That sugary drink with lunch or a couple of sweet snacks are enough to throw off your sugar budget for the day, helping fuel the buildup of visceral fat. Why? Because when there’s more sugar in our blood than our bodies need, the surplus is converted into fat—stored most notably in the abdominal area, right where we don’t want it.

Don’t just take this article’s word for it—science backs up the concern. A study published in 2020 in the European Journal of Preventive Cardiology demonstrated that long-term consumption of added sugars and sugary drinks is linked to a higher percentage of visceral fat. It’s not just a theory; it’s proven in the lab.

Not-So-Harmless Indulgence: Alcohol

Let’s talk about everyone’s favorite social lubricant: alcohol. It might seem innocent enough, but alcohol often sneaks in a hefty dose of calories. Just one drink can have you overshooting your recommended daily calorie intake for maintaining a healthy weight—and those calories don’t just vaporize. They love to settle around your belly.

As dietitian-nutritionist Melissa Rifikin explains, alcohol is “often associated with abdominal fat.” She notes that, while moderate alcohol consumption may have genuine health benefits, going overboard can fan the flames of inflammation, harm the liver, and stoke the fires of excess abdominal fat. So maybe stick to happy hour, not happy all-night-long.

Trans Fats and Refined Grains: Hidden Belly Boosters

It’s tempting to put all fats in the same naughty corner, but not all fats are created equal. Some fats are healthy (like unsaturated fats), while others are not. In particular, trans fats top the list of the least healthy kinds, according to nutritionists.

Another silent saboteur? Refined grains. Unlike wholesome whole grains, refined grains have gone through a process—let’s call it “the great grind”—where key nutrients and fibers are stripped away. Food manufacturers remove the bran and the germ, leaving a longer shelf life but also robbing the grain of much of its nutritional value. That’s how we end up with white rice and white flour—ingredients known for their talent at helping belly fat accumulate.

Refined grains: stripped of nutrients and fiber, encourage belly fat

It’s not about eliminating fats and carbohydrates altogether, but about favoring the right kinds (and maybe saving white rice for special occasions).

In Conclusion:

Belly fat has been villainized, but science says it’s only dangerous in excess. From sugary foods and drinks to calorie-packed alcohol and nutrient-poor grains and fats—there’s a clear pattern in the foods that help belly fat thrive. Knowing the nutritional culprits is half the battle; the rest is about keeping an eye on how much makes it onto your plate. Opting for moderation and making thoughtful swaps (goodbye, trans fats!) can help you stay healthy—belly included. Now, what’s for dinner?
