Fruit juice is rich in vitamins and minerals but is just as sweet as soda or other sweetened drinks.
An example: A 8-ounce (248 milliliters) glass of unsweetened apple juice has 24 g sugar. More than half is fructose.
Research shows that high intakes of fruit juice can lead to weight gain. This is due to the excess calories it provides rather than the fructose it contains
To help reduce belly fat, you can still enjoy the water, unsweetened Tea or sparkling wine with a slice of lemon or lime.
SUMMARY
High amounts of fruit juice can cause weight gain as they contain as much sugar as soda. You should limit your fruit juice intake and drink water or unsweetened Tea.
