A glass of sparkling waterSparkling water fans might be interested to know the carbonated drink may “promote weight loss”, according to a recent paper published in the BMJ Nutrition Prevention and Health.The study suggested the fizzy drink might enhance glucose uptake, thus “speeding up” our metabolism, which is the rate at which the body uses and converts energy.But is it that straightforward? Here’s what you need to know...Why does the paper say sparkling water boosts your metabolism?The authors of the paper said that part of the reason the drink has been linked to potential weight loss is because it keeps you feeling full.But they also claim it might create a slight uptick in how much blood glucose our cells use (or how “fast” our metabolism is). The more energy your body uses at rest, the more calories you burn, which can lead to weight loss. Researchers aren’t sure why sparkling water might cause that change, but this paper compared the process of drinking fizzy water with haemodialysis, where blood is filtered to remove waste and excess water.&
