"Bajar de peso rapidamente" is a Spanish phrase that translates to "Lose weight fast" in English. The literal translation of "bajar" is "to lower," but in this circumstance it is more accurate to translate it as "to lose."
There are many "lose weight fast" plans advertised in the United States. Translating these advertisements into Spanish is an ideal way to broaden the audience that they reach. Products such as Garcinia Cambogia and "It Works" promise flatter tummies and an all-around slimmer look. English- and Spanish-speaking consumers should research and evaluate these products before making use of them, since some have been known to cause harm.
