If you’re trying to lose weight, reducing your sodium intake may directly and indirectly help you succeed. Your body needs sodium to control blood pressure and blood volume and maintain proper functioning of your nerves and muscles. Sodium is a natural component of a variety of foods, but it’s added to many high-calorie, processed foods, too. According to the 2010 U.S. Dietary Guidelines, sodium consumption is positively associated with calorie consumption. Salt also causes you to retain water, which tips the scales upward. By reducing your sodium intake, you may lose weight and also reap other health benefits.
