Psyllium husk can be a great addition to help you maintain and achieve a healthy weight. “As a dietary fiber, consuming it can support a feeling of fullness, which can help you not overeat,” says Doll. “It can also support detoxification by binding to toxins in the gut and helping remove them from the body.” To use, mix 1 tablespoon of psyllium husk powder into at least 12 ounces of water and consume immediately. Doll says to start with small amounts, gradually increase over several weeks, and be sure to drink plenty of additional fluids throughout the day.
