Experts are exploring whether carbonated or sparkling water could aid weight loss by influencing blood sugar levels. A study published in BMJ Nutrition suggests that the CO2 in sparkling water increases glucose uptake in red blood cells, potentially boosting metabolism and lowering blood sugar. However, the effects are minimal and may not be significant enough on their own to impact weight loss. While some benefits, like increased fullness or reduced blood sugar, have been noted, these findings are still largely theoretical and require more research in humans.
The study compares drinking sparkling water to hemodialysis, noting that while CO2 conversion is similar, the duration of its effects makes it unlikely to play a major role in weight loss. However, potential downsides like bloating or gas may offset any benefits. Experts advise moderation and caution, emphasizing that a balanced diet and exercise remain key components for weight loss.
Takahashi explained that testing blood glucose levels immediately after consuming carbonated water might result in a lower reading, potentially leading to an underestimation of the actual blood glucose level.
