Not only sweet sodas contribute to weight gain, but also ordinary sparkling water (including sparkling mineral water), in which there is not a single gram of sugar. Scientists from Birzeit University (Palestine) argue that carbonated water encourages a person to eat more, which, in fact, leads to weight gain, according to the online edition for girls and women from 14 to 35 years old Pannochka. net According to scientists, the carbon dioxide contained in such soda not only does not make us feel full, as it was previously believed, but, on the contrary, encourages us to eat more. Studies have shown that when we ingest this gas with a drink, levels of the key hunger hormone spike..

In experiments involving rats, it was shown that rodents fed non-carbonated drinks with sugar, who were on a normal diet, did not gain more weight than those rats who drank water without sugar.. But as soon as carbonated drinks, including those that did not contain a single calorie, were included in the diet of animals, the rats began to get better..

This was due to the fact that the level of the hormone ghrelin increased in the body, which causes a feeling of hunger, not only in rats, but also in humans..

Then the authors of the study conducted an experiment involving 20 healthy volunteers.. And in this case, carbonated water at breakfast led to an outbreak of ghrelin levels: their levels of this hormone rose 6 times higher than in people who drank still water..
