Are diet drinks effective for calorie control?
A recent study in the US suggests not...
The large scale cross-sectional study found that overweight and obese people drink more diet drinks than healthy-weight people, but still consume the same amount of total calories as those drinking sugar-sweetened drinks. In these individuals the reduction in calories from the diet drink was negated by consuming extra calories from food.
Although the diet drinks reduced the calories consumed from drinks, this was counterbalanced by people eating more food than people of a similar weight who drank sugar-sweetened drinks.
