How Salt Affects Your Weight ?

Salt does not cause you to gain or lose fat. In fact, salt has no calories. High consumption of salt only results in temporary weight gain as it causes your body to retain water. Conversely, low consumption of salt can result in temporary weight loss as it causes your body to expel water.It is interesting to note that many crash diets which boast quick weight loss rely on foods with little or no salt content. The weight loss is mostly water, and as you eat foods containing salt again you regain the weight.As for the Salt versus the Sodium ,We add table salt (sodium chloride) during cooking and at the dinner table to enhance the flavor of our food. Manufactures add it to return flavor to processed foods and help preserve them. But when we look at nutrition content, we look at sodium. Salt and sodium are not the same thing. Sodium, which is found naturally in most foods, accounts for approximately 40% of table salt.Thus when salt is added to food, the sodium content increases by approximately 40% of the amount of salt added.

Why Salt Causes Water Retention

Our bodies rely on electrolytes, most significantly sodium and potassium, to carry the electrical impulses that control our bodily functions. In order for our bodies to function properly, it is important that the concentration of electrolytes in our bodies remain constant.A high concentration of electrolytes in our blood triggers our thirst mechanism, causing us to consume adequate amounts of water to return to the proper concentration of electrolytes. This is one of the reasons bars provide free salty snacks like pretzels and peanuts. The salt causes us to become thirsty and purchase more drinks.When we consume an adequate amount of water, our kidneys are able to keep the concentration of electrolytes in our blood constant by increasing or decreasing the amount of water we retain. The result of our retaining more or less water in our bloodstream can also affect our blood pressure.The water moves beyond our bloodstream, too. Through the process of osmosis, water flows from a lower salinity environment to a higher one in an attempt to balance the levels of salinity. After we consume large amounts of salt, it is the water moving from our bloodstream into our skin that gives us that "puffy" look and makes it hard to get our rings off. Then, when we consume lesser amounts of salt, the same process works in reverse to remove the excess water from our bodies.
