A recent study has revealed that replacing diet beverages with water can significantly enhance weight loss and boost diabetes remission rates among women suffering from type 2 diabetes and obesity.

Dr. Hamid Farshchi, the lead researcher, pointed out that these findings challenge the common perception that diet drinks are safe for weight management and blood sugar control.

He emphasized the need to promote water as a healthier alternative to low-calorie beverages for those managing diabetes and weight.

Previous research has suggested that artificial sweeteners might adversely affect blood sugar and fat metabolism, potentially increasing feelings of hunger.

The study was conducted by Dr. Farshchi and presented at the American Diabetes Association's 85th Scientific Sessions held in Chicago from June 20-23, 2025.

Involving 81 overweight women with type 2 diabetes, the study consisted of a six-month weight loss program followed by a year of maintenance.

Participants were randomly assigned to either a water group or a diet beverage group during the 18-month study.

According to the CDC, approximately 20% of Americans consume diet drinks on a daily basis.

Women in the water group experienced an average weight loss of 15 pounds, while those in the diet soda group lost about 10 pounds.

Statistical analysis showed that the water group lost an average of -6.82 kg compared to -4.85 kg in the diet beverage group, with significant results (P < .001).

Health markers such as blood sugar levels, insulin resistance, and triglycerides showed significant improvement in the group that consumed water.

The water-drinking group also saw enhancements in various health metrics, including BMI, fasting glucose, postprandial glucose, insulin levels, triglycerides, and insulin resistance.
