Why do people say that drinking water can help with weight loss?

When you feel full, you eat less. Drinking water before meals makes intuitive sense. Your stomach has nerves that sense when it’s being stretched and send signals to your brain that it’s time to stop eating. It’s possible that drinking before a meal could send similar signals.

You’re not hungry, you’re thirsty. This explanation suggests that we sometimes head to the kitchen for something to eat when we’re actually thirsty rather than hungry. If so, drinking calorie-free water could save us from consuming unnecessary calories—and that could promote weight loss.

When you’re not dieting or watching your diet, choosing to drink water instead of high-calorie beverages can help you consume fewer calories.

Drinking water can stimulate your body to break down fat without raising blood sugar or insulin, which can also help with weight loss.

In short, drinking water before a meal makes you feel full, which prevents you from overeating and also helps with food processing. So if you’re trying to lose weight but can’t seem to stop overeating, try drinking a glass of water before a meal.
