In the wise words of DJ Khaled, “water is the key to success.”

After last week’s column of bacon-grease-laden gumbo and a whole month of ingesting fat and sugar, it’s time to detox. As appealing as trendy juice cleanses starting at $60 a day are, there’s a cheaper option.

The point of a detox is to flush toxins and impurities out of your system. Unlike a juice cleanse, which offers vitamins and nutrients along with flushing your system, water is simply water. So don’t just drink it for three to five days straight without any other form of nutrition.

The Mayo Clinic recommends that men drink 3 liters of water a day, and women 2.2. A gallon of water carries around 3.7 liters and is frequently seen carried around campus by really buff dudes. But the gallon challenge, the trendy Internet name for drinking a gallon a day, does have health benefits for anyone, no matter how much they bench press.

Speaking from experience, it’s also a workout in itself lugging that gal’ around a frigid campus. Another added benefit is that a gallon of water is just about how much it takes to get the taste of a protein bar out of your mouth.

Another option besides water from the tap is coconut water. Thanks to trends and the new year health craze, this nut water is pretty easy to find and comes in several flavors. Coconut water prides itself on having electrolytes, like the lightning bolt Gatorade brand. But coconut water’s sweetness comes naturally, unlike the 30-plus grams of sugar in a bottle of lemon-lime Gatorade.

Infused water is popular from spas to campus dining halls to Jeni’s ice cream — another great diet spot. As refreshing as ice cold water is, let’s be honest, it can get bland real quick. Adding combinations of fruits, vegetables and herbs — such as cucumber and mint, lime and rosemary, cranberries and lemons — can add enough variety to your intake to make one gallon no problem.
