A strategic use of a diet soda to get you through a sugar craving may keep your diet on-track, but a new research review indicates that diet sodas don’t actually help you lose weight. A collaborative project headed by researchers at the Imperial College London’s School of Public Health found that consuming diet drinks might cause people to eat more calories by stimulating their sweet-sensitive taste buds. (They also found that much of the research showing a link between diet sodas and weight loss was financed by food and beverage companies.)
Many nutrition experts disagree with this finding and believe that zero-calorie beverages can help people manage calorie intake. The bottom line seems to be that they are better than a full-sugar soda, but the smartest plan is to wean yourself off that sugary taste.
