To lose weight you must drink a lot of water. That message can be read on many Internet sites about losing weight. But is that right? 5 Helpful tips with losing weight by drinking water.
Water does not contain calories. If you drink water instead of soft drinks, beer or wine that do contain calories, you will obviously lose weight. Stop drinking soda - Stop sugar.
The claim that drinking a few glasses of water before the meal gives you a feeling of satisfaction, and thus ensures that you eat less and thus waste, seems plausible. But research about this gives conflicting results. What drinking water really does for your skin. Indeed, some studies show that people who drank one or two glasses of water before meals eat less (on average about 75 calories less) and lose more weight than people who did not drink water. But other research could not show any effect.
There is no evidence for the claim that drinking a lot of water (more than 1.5 l per day) improves the metabolism and helps to remove waste or burn fat. There is also no evidence for the claim that a glass of lukewarm or warm water in the morning speeds up digestion or stimulates fat burning, and thus helps to lose weight. This may have a positive effect on bowel movements, but that has nothing to do with losing weight.
The claim that drinking ice cold water helps to lose weight is true, but the effect is limited. Drinking water lowers the blood pressure.
The idea behind this statement is that cold water in your body is heated up to 37 ° C. Energy is needed for this and calories are burned. That is indeed true, but it involves minimal quantities. To warm up half a liter of cold water to body temperature, your body burns about 16.5 kcal or 69 kJ. What is little, on a daily diet from 2000 to 2500 kcal. But of course all the bits help.
Conclusion: Drinking water literally is not enough to lose weight. Only if you eat less than you consume do you fall off. This has nothing to do with how much water you drink extra. But if you want to lose weight, it is a good idea to drink cold water instead of sugar-containing soft drinks or alcohol.
