Los cuatro casos de “Flaca Gorda” (Skinny Fat)

skinnyfatEl término “Flaca Gorda” es una contradicción.

Al igual que un abogado que gane poco o una animadora de la sociedad Mensa.

El término “flaco” generalmente se asocia con peso bajo, mientras que la gorda se asocia con el sobrepeso.

“Flaca Gorda” se refiere a alguien con niveles inapreciables de masa muscular junto a un alto porcentaje de grasa corporal. Básicamente, no es un gran punto a favor para la temporada de apareamiento…

Aquí hay cuatro razones por las cuales las personas tienen el aspecto de “Flaca Gorda” (Skinny Fat).

1

Hacer mucho cardio.

La investigación es bastante clara en este sentido. Si la fuerza y la hipertrofia muscular es su objetivo, el trabajo aeróbico lo obstaculizará. El ejercicio aeróbico canibalizará la masa muscular.

Estas son algunas de las referencias clave:

Comer muy poco

Por supuesto que lo más natural que se puede hacer cuando se desea perder grasa corporal es restringir el consumo calórico. Las personas “Flacas Gordas” (Skinny Fat) llevan ese axioma muy lejos. Si usted desea mantener su masa muscular mientras que restringe sus calorías, incrementar su consumo de proteínas será clave.

Tener miedo de consumir grasas

Las “Flacas Gordas” (Skinny Fat) comparten el miedo a la grasa en su dieta como una de sus debilidades. Por ejemplo, ellas son las personas que ponen en Facebook comentarios como “No es cierto que comer nueces te engorda?”

It makes me laugh when I see dieticians recommend “low fat snacks” such as pretzels over nuts like pistachios to obese, while the research shows them to be completely wrong:

If anything, regular nut consumption helps achieve optimal body composition.

Abstenerse de hacer entrenamientos de fuerza

El entrenamiento de fuerza tiene más beneficios para la composición corporal que lo que la mayoría piensa.

Esto es lo que la investigación tiene que decir al respecto:

En resumen, si desea obtener un físico que deletree respeto, evite las cuatro trampas.
