2-Day Fasting Diet

Two-day fasting diets claim they can clear your head, your GI tract and give you a jump start on your diet. According to Dr. Don Colbert, author of "Toxic Relief", a simple two- to three-day liquid fast gives your digestive tract a rest and prompts your body to release waste products. Fasting is also very spiritual and can be a way to relax your mind, body and emotions, notes Vanderbilt University. Consult your doctor prior to beginning a fast.

Water Fasts

Some fasting diets recommend you drink water, or nutrient-enhanced water only while following the diet. Diets such as the Master Cleanse, the Detox Cleanse and the Fasting Diet are diets that encourage water and water-enhanced liquid for two days or more. Some of these diets recommend you add fresh lemon, lime, grapefruit, cayenne pepper, honey or maple syrup to your water and that you drink eight to 12 cups a day. MayoClinic.com notes that following a fasting diet can be dangerous and cause fatigue, dizziness and nausea.

Juice Fasts

Juice fasts provide your body with more nutrients and calories than water only fasts, but can still be dangerous. A proper juice fast will provide you with a variety of fresh fruits and vegetables for juicing to drink throughout the day. Juice fasts raise the alkaline level in your body to help with detoxification, according to Dr. Colbert. Advocates of juice fasting recommend drinking fresh juice and avoiding processed or pre-bottled juices.

Weight Loss Benefits

Following a two-day fast may help you jump-start your weight loss goals. The American Journal of Clinical Nutrition suggests that alternate day fasting may increase the body's ability to lose fat. Drinking your calories for a day or two can help break the habit of binge eating and boredom eating. This can give you a feeling of starting fresh with a healthy diet after following a two-day fast.

Cautions

Fasting diets are often void of calories or are extremely calorie-restrictive. When following a fast, you should always decrease your physical activity level. Opt for easy stretching, meditating, easy walking and gentle yoga while on your two-day fast.
