A diet based on healthy foods and adequate hydration can help you lose weight.

Losing weight can be a challenging endeavor. Eating right and getting the correct amount of rest and daily exercise factor in to your ability to safely lose unwanted pounds. Another important aspect of weight loss is hydration and urination. Understanding how the body functions when when you are properly hydrated, urinating frequently and eating healthy foods helps you understand the effect of increased urination when dieting.


Weight loss and urination are related. Increased urination is a side effect of losing weight by undertaking a healthy approach to dieting. Because losing weight requires you to eat fewer calories than your body burns, the most effective way to increase your ability to burn calories, or your metabolism, is to exercise. While increasing exercise burns more calories, it also boosts your metabolism as you replace fat with lean muscle. With an enhanced metabolism your body produces an increased amount of waste in the form of water from cells, urea from protein digestion and ketones from burning fat as energy. This waste has the effect of increasing the amount of urine you expel when dieting.

Proper Liver Function

Another result of increased urination during weight loss is liver function. Because everything you put into your body is filtered through the liver, liver function and weight loss are interrelated. The liver is responsible for processing foods and liquids. When you overeat, the liver will store the excess calories in the form of glycogen. During dieting, fewer calories are consumed and your body will compensate by relying on stored glycogen. A by-product of metabolizing glycogen is increased urine production and urination, according to ShapeFit.

Effects of Healthy Practices

The amount you need to drink to stay hydrated depends on your level of activity, according to Health Media Ventures. Fluid consumption comes from both liquid and food sources. Health Media Ventures suggests certain fruits, such as cantaloupe and grapefruit, and vegetables, such as broccoli and spinach, contain as much as 90 percent water. Because dieting typically involves eating nutritious meals made up of fresh fruits and vegetables, your body will process this added hydration. As a result you will experience increased urination. Additionally, proper hydration is essential to losing weight. According to Changing Shape author Michael A. Smith, MD, increased hydration has a positive effect on your metabolic rate. Because water has a thermogenic effect, or increased heat during digestion, it raises your ability to burn calories at a higher rate, which in turn increases your weight loss. As you increase consumption of fluids, you likewise increase your need to urinate.


Diuretics, or water pills, are often used to lose weight. Diuretics work to reduce the amount of water you retain in your body, according to Weight Loss Guide. Losing water, or water weight, through the use of diuretics causes excess fluids to be expelled through your urine. As a result, you lose weight and experience an increase in urination.


If you experience unexplained weight loss and excessive urination, consult your physician. Certain diseases, such as diabetes, count sudden weight loss and frequent urination as a sign and symptom. Also, using diuretics to lose weight has dangerous side effects including an imbalance of electrolytes, a decrease in potassium levels and permanent kidney damage, according to Eating Disorder Treatment Centers.
