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 173 kcal/day in energy intake and 21 g/day in fat intake.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Adults with type 2 diabetes who drink 1 liter of water before each meal for 8 weeks consume 173 fewer calories and 21 fewer grams of fat per day than before.
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 173 kcal/day in energy intake and 21 g/day in fat intake, suggesting that hydration before meals may suppress appetite and reduce caloric consumption.
Drinking water before a meal stretches the stomach, which sends signals to the brain to reduce hunger. At the same time, the water lowers the concentration of salts in the blood, which tells the brain to stop releasing a hormone that increases blood sugar and fat storage. With less of this hormone, the liver makes less sugar and the body stores less fat, and the person eats less because they feel full sooner.
What the research says
1 studyThis study found that people with type 2 diabetes who drank a liter of water before each meal ate less food and lost weight, likely because they felt fuller. This matches the claim that drinking water before meals helps reduce calories and fat intake.
