sweetened drinks cause all muscles to use sugar for energy rather than burning fat...

A recent study published in the European Journal of Nutrition revealed that just four weeks’ consumption of sugar-sweetened beverages, including fruit juices, alters the body’s metabolism so that the muscles use sugar for energy instead of burning fat.

Dr Hans-Peter Kubis, who led the research at Bangor University, said: "Our results give a stark warning against regularly drinking sugar-sweetened drinks…it seems that our muscles are able to sense the sugars and make our metabolism more inefficient, not only in the present but in the future as well."

In the study researchers investigated the effect of SSBs (sugar-sweetened beverages) on healthy, lean individuals. Body composition, respiratory exchange ratio (RER), insulin sensitivity, muscle metabolic gene and protein expression were assessed before and after. After four weeks of drinking SSBs (about 140 grams of glucose a day), data showed a reduced ability to burn fat: muscle metabolism became less efficient and underwent a persistent shift to preferentially burning sugar and storing fat. This is the unhealthy adaptive change that occurs in the obese and diabetic.

What’s more - diet sodas may be worse than your regular sodas. A study at France’s National Institute of Health and Medical Research, found that diet sodas containing artificial sweeteners, spiked the risk of type 2 diabetes.
