Many studies show that drinking more water may benefit with weight loss. How much water depends on the individual. For example, someone who is more active or sweats more, needs more water than someone who isn't as active or sweats as much. If you find you have a headache, are constantly hungry or have trouble concentrating, chances are you are dehydrated. A general guide line would be to aim for 1-2 litres of water a day.
How drinking water can help you with weight loss;
· Drinking water cuts calories - The more water you drink, the fewer calories you consume. Drinking more water could help you stay away from high sugary drinks such as soft drinks, juices and sports drinks. Also, thirst can sometimes get confused with hunger. Drinking water or eating fruits and vegetables, which are high in water content, may help curb that craving and help keep you full and hydrated.
· Drinking water reduces fatigue - Too tired to exercise? Dehydration can make you feel sluggish and tired. Increasing your water intake can help you improve your mood and reduce fatigue. The colour of your urine is a key indicator of hydration. Typically, your urine will be very light coloured if you are well-hydrated, if your urine is dark, then you likely need more water.
· Drinking water may boost metabolism - Increasing your water intake can also increase your metabolism. Studies have shown that within ten minutes of drinking water, your metabolic rate can increase by 30% for both, men and women. It reaches its peak 30-40 min after drinking and can last for over an hour. The researchers estimated that drinking 1 litre more of water than you would normally drink can increase your daily energy expenditure by 200kj.
