Diet drinks and food actually trigger weight gain and diabetes, says new study
Diet drinks or foods may actually promote weight gain and trigger diabetes because the brain misreads the number of calories present and reduces metabolism, a new study suggests.
Researchers at Yale University in the US discovered that the body stops burning energy from food if there is a ‘mismatch’ between food sweetness and calories.
In nature, sweetness signals energy and the greater the sweetness the more calories are available, so the brain has evolved to expect the two to come together. When they do not, the brain can become confused, thinking there are fewer calories to burn.

The scientists say it could help explain previous studies that have suggested that artificial sweeteners can increase blood sugar levels and possibly trigger diabetes.
“A calorie is not a calorie,” said senior author Dana Small, Professor of Psychiatry at Yale University School of Medicine.
“The assumption that more calories trigger greater metabolic and brain response is wrong. Calories are only half of the equation; sweet taste perception is the other half.
“Our bodies evolved to efficiently use the energy sources available in nature. Our modern food environment is characterized by energy sources our bodies have never seen before.
“When sweet taste and energy are not matched less energy is metabolized and weaker, or inaccurate, signals are sent to the brain. Either one of these effects may affect metabolic health.” Continue reading
