The sweetness in naturally sweetened foods tells the body the food contains energy, and the sweeter the food, the more energy it usually contains.

The researchers also said this study might help in explaining prior studies that reported that the artificial sweeteners has the potential to increase the blood sugar levels and possibly lead to diabetes. But in modern-day life, the body's metabolism is fooled when a beverage is either too sweet or not sweet enough for the amount of calories it contains.

That means that a sweet-tasting, lower-calorie drink can trigger a greater metabolic response than a drink with higher calories, they said. When sweetness and calories are matched, the calories are metabolised, and this is registered by the brains reward circuits.

Commenting on the paper, Dominic Dwyer, Professor of Psychology at Cardiff University, said: "What the paper does imply, correctly in my view, is that mismatches between calories and sweetness interfere with metabolism of calories in a way that could have negative impact on weight gain, diabetes, heart disease etc. but that determining the link between the unprocessed calories and metabolic health needs future work". The assumption that more calories trigger greater metabolic and brain response is wrong. As a result, the person could be compelled to overeat. "Calories are only half of the equation; sweet taste perception is the other half", Small said in a university news release.

But diet products that do not taste sweet confuse the brain into thinking there are fewer calories to burn than there are. Many processed foods have such mismatches, such as yogurt with low-calorie sweeteners.

"Our bodies evolved to efficiently use the energy sources available in nature", Small said.
