Everyone knows that water is an important part of our lives. The question is can water help you lose weight? The simple answer is YES.

Although no one is guaranteeing that drinking water before bed or at any other time of the day will make you wake up lighter, but there is evidence to support this : Since 60% of your body is made up of water, the clear, calorie-free liquid is involved in almost all bodily processes. According to research, the better hydrated you are, the more efficiently your body performs tasks like thinking and burning fat.

"The calorie savings can add up quickly, as long as you don't make up for those calories by leaving the coffee shop with a muffin and water rather than your typical flavoured latte," she said.1

Even though diet drinks don't carry any calories, switching to water instead may help certain individuals shed weight. Overweight and obese women who changed to drinking water instead of diet beverages saw greater weight loss following their main meals. The extra weight loss in those who drank water may have resulted from consuming fewer calories and carbohydrates, but more research is required, the researchers noted. Many diet drinks still hydrate and cut calories when substituted for sugary drinks, so they might aid in weight loss for some people.2

Reasons why you should drink water for weight loss

  • Your appetite may be naturally suppressed by water

When you become aware that you are hungry, your first reaction may be to look for food right? but food may not be the solution. The brain frequently confuses thirst, which is caused by mild dehydration, with hunger. When the stomach feels full, the brain receives signals to stop eating. By helping to fill up the stomach, water can help people feel fuller and longer and eat less.

Another scenario is when someone believes they are hungry when they are thirsty. To avoid mindless snacking, try drinking a glass of water before reaching for a snack.

In a 2014 study trustedd sourcee, 50 overweight women drank 500 milliliters (mL) of water in addition to their usual water intake for 8 weeks. They did this before breakfast, lunch, and dinner.

The participant's body weight, body fat, appetite, and body mass index all decreased.3

  • Water aids in the body's waste removal

It becomes difficult for your body to properly eliminate waste such as urine or faeces when it is dehydrated.

While maintaining vital nutrients and electrolytes, water aids in the kidney's ability to filter toxins and waste. The kidneys hold onto water when the body is dehydrated.

Hard or lumpy stools and constipation are other symptoms of dehydration. Water facilitates the movement of waste by lubricating or softening hard stools.

Additionally, drinking water can aid in the body's recovery from gastrointestinal issues like indigestion and diarrhoea.

People may feel bloated, swollen, and tired when waste accumulates in the body. To avoid retaining waste which could result in a few extra pounds or an enlarged waistline due to bloating, you must ensure you stay hydrated.4

  • Drinking water could boost motivation and lessen stress

Your desire to work out, prepare meals at home, and make healthier food choices may be impacted by these symptoms.5

  • Water consumption can lower total liquid calorie intake

By consuming soda, juice, or sugary drinks, it is simple to consume liquid calories. The majority of people also disregard the calories in alcoholic or sports drinks.

Long-term weight loss benefits may result from substituting water or other calorie-free beverages, like herbal tea, for even a few high-calorie drinks per day.

A group of obese females experienced an average weight loss of between 2 and 2.5 percent after switching two or more high-calorie beverages for non-caloric ones every day for six months, according to the authors of a 2012 study.6

  • Water fasting

Weight loss and a lower risk of developing some chronic conditions are just two of the potential health advantages of water fasting. It may not be appropriate for everyone because it carries some risks. The practice of fasting, which involves limiting one's intake of food, dates back thousands of years.

A type of fast that only allows water is known as a water fast. It has become more well-known recently as a quick weight-loss technique. According to studies, water fasting might be good for your health. For instance, it might reduce the risk of some chronic illnesses and promote autophagy, a procedure that aids in the body's breakdown and recycling of old cells.

However, there are very few studies on water fasting in humans. Additionally, it poses some health risks and is not recommended for everyone.7

When should you drink water to lose weight?

Drinking water? prior to meals may aid in reducing hunger and preventing overeating. Additionally, since water can aid in digestion, think about sipping some after a meal. Sass advises spreading out your water intake throughout the day, though, in general.

Additionally, Do points out that some drinks contain additives like caffeine that increase urine production. They, therefore, have the exact opposite, dehydrating effect. While you don't have to switch to decaf to stay hydrated, he advises trying to recognize when more water intake is advised, such as when you are exposed to hot weather or engage in physical activity, and making sure to rehydrate in response.8

How much water should you drink?

The usual "2 litres of water per day" rule may be familiar to you, but in actuality, the amount of water required varies significantly depending on factors like age, gender, health, physical activity, the tendency to perspire, and more. The majority of healthy people let their thirst be their guide to determine how much water they need each day. 

According to the U.S. National Academies of Sciences, Engineering, and Medicine, men should consume approximately 15.5 cups (3.7 litres) of fluid per day. Women should drink about 11.5 cups (2.7 litres) of fluid each day. Checking your urine while or after urinating is one way to find out if you're getting enough water. It's best to determine your hydration level based on the colour of your urine. If it's dark yellow, you aren't drinking enough; if it's light yellow, you are.9

Summary

Drinking more water can help you lose weight and promote other positive health outcomes, but it should only be a small part of your overall wellness strategy because drinking water is not going to have a huge weight loss effect, and without calorie restriction and/or exercise, just drinking water is not likely to lead to significant weight loss.
