Drinking at least one glass of low-sodium vegetable juice daily may help overweight dieters lose more weight.
In a study, adults who drank at least 8 ounces of vegetable juice as part of a diet lost 4 pounds over 12 weeks, while those who followed the same diet but did not drink the juice lost only 1 pound. The vegetable juice drinkers also significantly increased their intake of vitamin C and potassium, while decreasing their overall carbohydrate intake.
It's possible that vegetable juice helps reduce appetite. In addition, vegetable juice drinkers are more likely to get the recommended 3 to 5 servings of vegetables daily.
