We all have bad habits, and moments of weakness. Whether it’s continuously indulging in the third large cup of coffee, just one more slice of pizza, or too much beer at Tuesday’s happy hour, the result is the same: You feel like crap, after. But there’s good news—you can detox your system to get back on track with your fitness goals. And you don’t have to starve yourself on an extreme liquid cleanse diet to do it.

Dietary changes are necessary during a time of detoxing,” says Dr. Ivy Bravin, a naturopathic doctor based in New York, “but they don’t have to be radical.” Upping your water consumption, lounging in a sauna, and opting out of dairy products for a week can do wonders for you and your hardworking toxic-filtering organ, the liver. Incorporate these (and more) simple detox steps into your life, and your body will feel more energized in no time.
