Often, we wonder why we are overweight, typically blaming diet and genetics as the cause, but a study at Birzeit University, in Palestine, cites results of rat testing, showing elevated ghrelin after drinking “fizzy” water. The belief, carbon dioxide increases ghrelin. Though only rats were tested, a fact irking the British soft drink association, it points to ghrelin as a possible culprit. When humans drank it with breakfast, it showed ghrelin levels six times above normal. Clearly, further studies need be done with humans, before positing it as the cause of obesity.

Key Takeaways:

• Researchers at a Palestinian University have been monitoring two rodent groups, one fed normal, still water, the other sparkling water.
• The results have shown the sparkling water consuming rats as gaining more weight than their still water counterparts.
• A separate study showed humans that had sparkling water at breakfast had six times as much gherlin, a hunger-inducing hormone, in their system, then those that did not partake.

“Sparkling water, often viewed as the healthier alternative to other carbonated soft drinks, could trigger a ‘hunger hormone’, according to scientists.”
