In an interview for the September issue of Ladies' Home Journal, Mrs. Obama says she recently was on what she calls a "sort of cleanse" in which she was just eating vegetables.
A cleanse can involve a temporary change in diet promoted to rid the body of toxins.
Mrs. Obama doesn't give a lot of detail about her cleanses, saying that she might do one for two days but that it's not a way of life for her because, as she puts it, "I like food too much."
Mrs. Obama has a campaign against childhood obesity.
