What it is and how to eat it
The Diccionario de americanismos defines a patacón as a slice of green plantain that is smashed and fried, and records the word in Honduras, Costa Rica, Panama, Colombia, Venezuela and Ecuador; the tostón, a large slice of green plantain smashed and fried that usually goes with other foods, appears in Honduras, Nicaragua, Panama, the Dominican Republic, Puerto Rico, southwestern Colombia and Venezuela. The boiled green plantain page explains what this cooking plantain is and how it is eaten boiled. This page covers fried green plantain according to USDA, with 309 kcal, 11.8 g of fat, 3.5 g of fiber and 36.1 g of water per 100 g, compared with 69.1 g of water for boiled green plantain.
An 80 g (2.8 oz) serving provides 247 kcal, 9.4 g of fat and barely 1.2 g of protein, so it is a side and works best next to the protein, which the 2025 nutrition advisory on GLP-1 therapy suggests eating first, such as fish, chicken, beans or fresh cheese. The same advisory suggests avoiding fatty or high-fiber foods in the first days of treatment, and in those days boiled green plantain fits better, at 97 kcal and 0.1 g of fat for 80 g. Later on, if they are well tolerated, a few patacones next to the protein and a salad give the crunch without fried food taking over the plate.
What the evidence says
According to USDA, fried green plantain has 11.8 g of fat per 100 g, compared with 0.08 g for boiled, and 309 kcal compared with 121, with much less water and much more fat. A little over 10% of its calories come from saturated fat, 3.69 g per 100 g, and the WHO recommends that saturated fat provide no more than 10% of total energy in the diet and suggests boiling or steaming instead of frying to reduce it. In the Wegovy (semaglutide) trials, according to its label, nausea affected 43.9% of patients, compared with 16.1% on placebo, and the NIDDK, part of the U.S. National Institutes of Health, notes that high-fat foods can increase bloating in some people. With 482 mg of potassium and 3.5 g of fiber per 100 g it meets the EU minimums for "source of potassium", 300 mg, and "source of fibre", 3 g (Regulations (EC) No 1924/2006 and (EU) No 1169/2011).
Satiety
The 1 to 5 score is our own estimate: it starts at 1 point, adds points for low energy density, for protein and fiber per 100 kcal, and for the water in solid foods, and subtracts points for drinks with calories. It is useful for comparing foods with each other; it is not a measurement in people.

It is an estimate based on its composition, not a measurement in people.
What should I know about fried green plantain (tostones) if I take Ozempic, Wegovy, Mounjaro, or Zepbound and feel nauseous?
Based on our tags, this is what matters about fried green plantain (tostones) on a GLP-1 medication. “High in fiber”: a good amount of fiber, which helps keep you regular; it is easier to tolerate when you increase it gradually and drink enough water. “High energy density”: a lot of energy in a small volume; when your appetite is very low, a small serving can help you meet your needs. “May worsen nausea”: a fatty or fried food; fatty meals are digested more slowly and can make nausea and heaviness worse. These are general guidelines, not medical advice: everyone tolerates foods differently.
What is a typical serving of fried green plantain (tostones)?
We use 80 g (3 oz) as a typical serving. That amount provides about 247 kcal, 1.2 g of protein, and 2.8 g of fiber. It is a reference for calculations, not a recommendation of how much to eat.
