You’re splurging on salt
Have you ever had a fast food meal and then later felt bloated? That could be because of an increase in water retention due to all the salt you ate. For people who eat too much sodium on a regular basis, the effects could be long-lasting. “Sodium plays a large role in fluid balance in the body,” says Erin Palinski-Wade, RD, a certified diabetes educator and author of Belly Fat Diet For Dummies. But, Murphy explains, “The higher sodium in our blood will demand a higher water volume to maintain homeostasis or balance of micro-nutrients in our blood,” she says. “This is also why high sodium will increase blood pressure.” And it’s not just table salt we’re talking about—highly processed foods and lunch meat also tend to be high in sodium, so read nutrition labels carefully.
You’re overdoing the carbs
Sugar and carbs (which turn into sugar) are also surprising triggers of water retention. “When you consume carbohydrates, they are converted into glycogen, which is stored in the muscle as energy,” Palinski-Wade says. “For every gram of glycogen stored, the body holds onto about three times as much water.” And 120 grams of glycogen contributes a pound of weight from water. Unless you’re burning through all your carb stores, as an elite athlete might, you’re probably retaining excess water. “When you overload on sugar or go on a carb binge, you hold onto more water as your body stores these excess carbs as glycogen,” Palinski-Wade says. Keep in mind that carbohydrates are good for you overall, and can be found in foods like fruit, grains, starchy veggies, and things like legumes. What you may want to avoid are refined carbs, which are typically processed foods that have had the fiber and nutrients removed, like white bread, white rice, pastries, and snacks. Worried you’re eating too many carbs—especially the wrong ones? There are warning signs to look for that suggest your carb intake is too high.

You’re on a fad diet or cleanse
Although you don’t want to eat too many carbs, you don’t want to cut out all carbs either. You might drop fluid fast at first as your body burns through your carb stores, but you won’t be able to maintain it. “Fad ‘fasting’ diets will typically be very low in carbohydrate, so we lose water weight quickly when the glycogen stores are not replenished,” Murphy says. “The only problem with that is when we eat a regular diet again, we re-gain it all with the glycogen stores being filled—and sometimes more, depending on the cravings we’ve denied ourselves, and the overeating we may be more susceptible to!” According to the American Academy of Nutrition and Dietetics, most fad diets, including Atkins and Zone, aren’t healthy, don’t result in long-term weight loss, and can even be dangerous for your health. “Red flags when following any diet plan are if the diet promotes avoiding complete food groups, is unsustainable for long periods of time, or promotes any one nutrient or product as a ‘detox’ or ‘cleanse,'” Palinski-Wade says. “The body cleanses itself using the liver and kidneys quite efficiently.” In addition, limiting calories too much can cause the body to hold onto water, she says. So if you’re looking for how to lose water weight permanently, keeping a nutritionally balanced intake is the way to go.
