When dieting, what we eat is as important as what we drink. Can this well-known adage, repeated over and over by many food specialists, become a slimming asset?
Bob Harper, a charismatic American sports coach, seems to believe so and has even made it his hobbyhorse. This slimming specialist became famous by publicizing his unstoppable technique for losing weight: drink several glasses of water before eating, while drastically limiting the number of calories ingested during meals.

This method, which has conquered many Americans, has also been strongly criticized by specialists who, while they agree that water is essential to the proper functioning of the metabolism, it should not be considered as a way to lose weight.

So is water really your slimming ally? Here’s how to see it more clearly.

When you are hungry, your body sends a signal to your brain to let it know that you are hungry, waiting for a response. But you should know that the same signal is sent when you are thirsty. In other words, an afternoon craving could be solved by simply drinking a glass of water.

When it is no longer an illusion but you are really hungry, water allows you to reduce this sensation by reducing your desire to eat. It acts as an appetite suppressant.

It is also important to know that water speeds up your metabolism. In other words, it gives your body more energy to function, and therefore to burn calories.

Calories that it also allows you to eliminate more efficiently. It is always water that allows your body to get rid of accumulated fat and waste.

Water will therefore help you optimize your efforts to lose weight
Two studies have proven this. The first, conducted by researchers at the University of Virginia, showed that in two samples of women who were on a diet, those who drank at least two liters of water a day (while the others had to drink only when thirsty) lost, on average, 2.3 kilos more than the second.

A second study, led by British researchers, also compared two groups of overweight people. While the first group had to drink half a liter of water half an hour before each meal, the second was invited to simply imagine the feeling of satiety before eating. Conclusion at the end of this experiment: the participants of the first group had lost, on average, 1.3 kilos more than those of the second group.

Does this mean that water is the best diet? No !
Many dieticians say that water is an ally, but not a determining factor. To lose weight, a healthy, balanced diet and physical activity are the only really effective remedies.

“Drinking water before meals can help to lose weight if the person in question adopts a healthier diet and increases his or her physical activity,” conclude the authors of the British study.

Drinking water to lose weight, yes but how?
For drinking water to be really effective, it is important to follow certain rules. Contrary to what was tested in these two studies, most nutritionists advise drinking water in reasonable quantities and regularly, rather than swallowing half a liter, or even two liters, in one go.

When we talk about water, we are of course talking about pure water. There is no need to drink two liters of coffee, tea or fruit juice, they will not have the same effect. This does not mean that you should stop drinking coffee to lose weight, simply that water only has all its virtues when it is consumed naturally!

To try the benefits of the appetite suppressant effect of water, it is recommended to drink one or two glasses, not more, about 20 to 30 minutes before eating. Be careful, this effect is short-lived, which is why you should not abuse it by drinking too much water, as this would only give you a good craving between two meals.
