The Claim

In adults with type 2 diabetes, consuming 1 liter of water daily before meals for 8 weeks is associated with a mean reduction of 32.6 mg/dL in fasting blood sugar and a 22.05 mg/dL reduction in triglycerides.

In plain English

Adults with type 2 diabetes who drink 1 liter of water before each meal for 8 weeks experience an average decrease of 32.6 mg/dL in fasting blood sugar and 22.05 mg/dL in triglycerides.

See the scientific wording

In adults with type 2 diabetes, consuming 1 liter of water daily before meals for 8 weeks is associated with a mean reduction of 32.6 mg/dL in fasting blood sugar and a 22.05 mg/dL reduction in triglycerides, suggesting a potential role in improving glycemic and lipid control.

Why this might work

Drinking water before meals lowers the concentration of salts in the blood, which tells the brain to stop releasing a hormone that tells the liver to make more sugar and fat. With less of this hormone, the liver produces less glucose and fewer fat particles, leading to lower blood sugar and triglyceride levels. The water also fills the stomach, reducing how much food is eaten, which further lowers blood sugar and fat over time.
