Cucumbers
Cucumbers are very low calorie vegetables that are great for weight loss. Cucumber juice is pretty tasty and easy to make. Cucumbers are quite juicy, and you will only need 1 large cucumber to make one glass of juice. Cucumbers are an inexpensive and are therefore cost effective vegetable for juicing.

Cucumbers are also very cleansing and are great for the kidneys, lowering blood pressure and producing clear skin.

Carrots
Carrots are great for weight loss because they make a substantial soup like juice that can be more filling than some other juices. A carrot juice just before a meal can help improve digestion and the feeling of satiety. The heftiness of carrot juice also makes it a good choice for a low calorie snack. Carrot is also one of the more sweet and tasty of vegetable juicer recipes. For this reason carrots are often mixed with sour (but extremely healthy) green vegetables like spinach, kale and broccoli.

The pulp left over from carrots can also be used to make healthy low calorie soups.

Negative Calorie Vegetables
Some vegetables are so low in calories that they are classified as negative calorie vegetables. This means that it takes more calories to digest these vegetables than they actually provide us! Asparagus, broccoli and dark leafy greens are great examples of negative calorie vegetables.

Diuretic Vegetables
Shedding excess water can help us shift a little weight and reduce the feeling of being bloated. Celery and (especially) asparagus are great diuretics that can help. If you make an asparagus juice be prepared to pass unpleasant smelling urine. This is normal when drinking asparagus juice and nothing to worry about.

Spice It Up
Mixing up hot spices with your juicing recipes could help burn up a few extra calories. Chili powder, pepper, cayenne, cardamom and allspice all have a stimulating effect upon the metabolism.
