Context matters. Honestly, it matters more than the dictionary when you're trying to figure out what is fat in Spanish. If you just look up the word and blurt it out, you might end up in a fight or, at the very least, a very awkward silence.
Language isn't just a 1:1 swap of words. It’s a minefield of culture.
The Literal Answer: Gordo and Grasa
If you're looking for the direct translation of the adjective "fat" (as in, a person or animal is overweight), the word is gordo. For a woman, it's gorda. Simple, right? Not really.
Then there’s the noun. If you’re talking about the white stuff on a steak or the lipids in your bloodstream, you use grasa. You wouldn't call a ribeye "gordo." That would sound ridiculous. You’d say it has a lot of grasa.
But here is where it gets weird. In many Spanish-speaking cultures, calling someone "Gordo" or "Gorda" is actually a term of endearment. You’ll hear husbands calling their wives "Gorda" and vice versa. It doesn't necessarily mean they think their partner is overweight. It’s more like saying "honey" or "sweetie."
Wait, don't just go calling random people gordo yet.
If you say it to a stranger with the wrong tone, it’s an insult. It’s all in the "how." The diminutive gordito or gordita softens the blow significantly. It’s like saying "chubby" or "pudgy," but in a cute way. Still, if you’re in a professional setting in Mexico City or Madrid, maybe just avoid it entirely.
Why Spanish Speakers Use "Gordo" as a Nickname
It’s a cultural quirk that trips up native English speakers every single time. We’ve been conditioned to see "fat" as a massive taboo—a word that should be whispered or avoided with euphemisms like "big-boned."
In Latin America? Not so much.

People are often nicknamed based on their physical traits. If you have curly hair, you’re Chino. If you’re skinny, you’re Flaco. If you’re a bit round, you’re Gordo. It’s descriptive, not always judgmental. According to sociolinguistics studies on Caribbean Spanish, these "apodos" (nicknames) serve as a way to build intimacy. By pointing out a physical trait, you're signaling that you're close enough to the person to be blunt.
But honestly, the line between "affectionate nickname" and "bullying" is paper-thin.
If you're an outsider, stick to the safe side. You haven't earned the right to call your coworker "Gordito" just because his best friend does.
Medical and Formal Terms
When you’re at the doctor or reading a health report, "gordo" is too slangy. It’s unprofessional.
If a doctor in Bogotá is discussing obesity, they use obesidad. The person is obeso or obesa. If someone is just a little overweight, the term is sobrepeso.
- Sobrepeso: Overweight (literally "over-weight").
- Obeso/a: Obese.
- Adiposo: Adipose (as in tejido adiposo or fatty tissue).
If you are reading a food label on a bag of chips in Spain, you’ll see grasas saturadas (saturated fats). You won't see "gordo" anywhere on the packaging.
The Nuance of "Estar" vs. "Ser"
This is the big one. This is what separates the beginners from the experts. Spanish has two versions of the verb "to be": ser and estar.
If you say "Él es gordo," you are saying that being fat is a defining characteristic of his identity. It’s a permanent state in your eyes. It feels harsher.

If you say "Él está gordo," you are implying it’s a temporary state or a change. Maybe he was thin last year and gained weight. Using estar is often perceived as slightly less "attacking" because it doesn't define the person’s entire essence. It’s a subtle shift, but native speakers feel it.
The "F" Word: Why Context Is King
I once saw an American student try to complain about "fat" in her food by using the word gordo. The waiter looked at her like she had two heads.
Food is oily? Use grasiento.
Food is fatty (like meat)? Use con mucha grasa.
Is the person just "big"? Use grande or robusto.
In the US, we use "fat" for everything. In Spanish, you have to branch out.
If you’re talking about a "fat" paycheck, you’d say a sueldo gordo, which is one of the few times "gordo" is used metaphorically for something good. Or the "Gordo de Navidad," which is the famous Christmas lottery in Spain. There, "Gordo" means the Big Prize. Everyone wants the Fat One.
Common Synonyms and Slang
- Rellenito/a: This means "stuffed" or "filled out." It’s the polite way to say someone is carrying a few extra pounds. It’s very common in Chile and Argentina when you want to be respectful.
- Entrado en carnes: This is an old-school, slightly poetic way of saying someone is "well-fleshed." It’s basically "stout."
- Macizo: Usually implies someone is big but strong. Like "solid."
- Panzón: Specifically refers to someone with a big belly (panza). It’s pretty informal and can be rude.
What about "Fat" in Science?
When we talk about the macronutrient—the stuff that gives you 9 calories per gram—we are strictly in lípidos or grasas territory.
Chemists don't play around with "gordo." If you're looking at a molecular structure, it's ácidos grasos (fatty acids).
There's a fascinating linguistic divide here. The Spanish language separates the human experience of body size from the biological reality of lipids much more strictly than English does. We use "fat" for the person, the steak, the nutrient, and the insult. Spanish forces you to choose a lane.

Regional Differences Are Huge
In Mexico, you might hear lonja to refer to a "love handle" or a roll of fat.
In Argentina, someone might be called a tanque (tank) if they are particularly large.
In Spain, fofo is a great word for "flabby"—someone who might not be huge but lacks muscle tone.
You have to listen to the locals. If you're in a gym in Medellin, the terminology will be vastly different than a dinner party in Barcelona.
Avoid These Mistakes
- Don't assume "graso" describes a person. If you say "Él es graso," you're saying he is made of grease or is oily to the touch. It sounds gross.
- Don't use "gordo" in a job interview. Even if you're talking about "fat margins." Use amplios márgenes.
- Do use the diminutive if you're unsure. Adding "-ito" to the end of words in Spanish acts as a linguistic shield. It shrinks the impact of the word.
Actionable Steps for Using Spanish Correctly
If you're actually trying to navigate a conversation in Spanish and the topic of weight comes up, follow these rules to avoid looking like a jerk.
First, observe the room. If no one else is using physical descriptors, you shouldn't either. Spanish culture can be very blunt, but it’s a "read the room" situation.
Second, use "sobrepeso" for health. If you are discussing fitness or health goals with a friend, sobrepeso is the clinical, neutral term that carries the least amount of emotional baggage.
Third, learn the food terms. If you're at a restaurant, remember:
- Grasoso = Greasy.
- Grasa = The fat on the meat.
- Magro = Lean (the opposite of fatty meat).
Fourth, understand the nickname culture. If someone calls you "Gordito," don't immediately get offended. Look at their face. Are they smiling? Is it a warm tone? They are likely welcoming you into their inner circle. It’s a weird way to show love, but it’s real.
Finally, practice the ser/estar distinction.
Saying "Estoy gordo" (I am fat right now/I feel fat) is a very common way to complain after a big meal. It’s much more natural than saying "Soy gordo."
Language is a living thing. It changes based on who is speaking and who is listening. "Gordo" can be a bullet or a hug. Choose which one you want to give.
