Leer el aviso completo
Cada número de esta página (objetivos de calorías, reparto de macros y cualquier plan de comidas sugerido) se obtiene con fórmulas (Mifflin-St Jeor para la tasa metabólica basal, multiplicadores de actividad estándar) o, en los planes de comidas generados por IA, con un modelo de lenguaje que aplica esas mismas fórmulas. En las páginas de planes de comidas, la cifra de carbohidratos de cada comida se calcula por diferencia: calorías totales menos las calorías de proteínas y grasas, dividido entre 4. No se mide ni se estima por separado, así que léela como un balance aritmético y no como un análisis nutricional independiente del plato. Nada de esto es asesoramiento médico o nutricional individualizado, y nada ha sido revisado por un dietista titulado, un médico u otro profesional sanitario con licencia.
Pregunta a tu médico o a un dietista titulado qué es lo adecuado para ti antes de empezar una dieta nueva, sobre todo si estás embarazada o en periodo de lactancia, tienes una enfermedad diagnosticada, tomas medicación con receta o has tenido trastornos de la conducta alimentaria. Si tienes una enfermedad renal u otra afección médica, consulta con tu profesional sanitario antes de aumentar la proteína.
Mealyno nunca recomienda un objetivo de calorías por debajo de tu tasa metabólica basal (BMR) calculada, la energía mínima que necesita tu cuerpo en reposo completo. Incluso el ajuste de pérdida de peso más agresivo se limita a ese mínimo.
Las estimaciones de calorías y de BMR usan la ecuación de Mifflin-St Jeor (Mifflin MD, St Jeor ST, et al. Am J Clin Nutr. 1990).

About this food: Pork backfat (salo)
Salo is almost pure fat: 88.7 g of fat per 100 g, with only 2.9 g of protein and no carbohydrate, which puts it at 812 kcal. A typical thin slice of 20 g comes to about 162 kcal, and that is the figure worth logging, since few people eat a hundred grams at one sitting.
The data here describes fresh, unsalted backfat. Salted salo, whether dry-cured or from a jar with garlic, has almost the same calories, because salt adds no energy, but it holds far more sodium. A piece with meat streaks, the kind sold as 'with a vein', differs a little: the meat adds some protein and lowers the fat per gram.
Weigh slices instead of counting them, because a hand-cut slice can easily be twice the typical one. Salo is usually eaten on rye bread with garlic and pickled cucumber, and the bread has its own entry. When salo is rendered into cracklings and lard, the fat drains away, but whatever stays in the dish still counts. Keep it wrapped in parchment in the fridge or freezer, since it picks up the smell of other food.
What it is high and low in
Pork backfat (salo) is high in vitamin D (21%) per 100 g (share of the daily reference in brackets). It is a good source of selenium (15%).
It is also high in nutrients with a daily limit: saturated fat (146%) (share of the daily limit). It is low in carbohydrate (up to 5 g per 100 g). The rule is the same for every food: "high" means at least 20% of the daily reference in 100 g, "good source" means 10-19%. For protein it takes at least 8 g per 100 g and a fifth of the calories from protein.
How it compares with similar foods
We compared pork backfat (salo) with the five foods in our table that are closest in composition (Raw ground beef 80/20, Cooked bacon, Raw ground pork, Raw pork loin and Cooked lamb), per 100 g.
Rank among the six: Protein (1 = most): 6th of 6; Calories (1 = fewest): 6th of 6; Carbohydrate (1 = fewest): 1st of 6. The order is computed from the USDA values, so it moves if the table changes.

Where the numbers come from
The values on this page come from USDA FoodData Central, SR Legacy (entry 167811: "Pork, fresh, backfat, raw"). It is the US government's reference database and its data is public domain (CC0). We retrieved it on October 4, 2026 and show it per 100 g of the food in the stated state (raw). When USDA reports no value for a vitamin or mineral we write "no data", never zero.
About how the food maps to the USDA entry: This is fresh, unsalted backfat. Salted salo has nearly the same calories but far more sodium.
The daily value column compares each amount with a reference adult: the average of the adult male and female values in the US and Canada Dietary Reference Intakes (age 19-30), a 2,000 kcal day and 50 g of protein. Sodium (2300 mg), sugar (90 g of total sugars, the EU reference intake) and saturated fat (22 g, under 10% of calories) are limits, not targets. These are general guides for healthy adults, not medical advice.
The portion weight is a typical size, not a USDA value, so weigh your own portion.
