There are several types of juice diets available. The most common type is a juice fast, in which people replace their meals with juiced fruits and vegetables.
The point is to lose weight by abstaining from solid food, while still ingesting a significant amount of nutrients from the juice.
Generally, the diets are very low in calories.
Some people do juice fasts for just a few days, while others go on them for weeks at a time.
Unfortunately, the effectiveness of juice diets is not well studied, but many people claim they produce quick weight loss.
Based on anecdotal evidence, it is clear that juice diets may lead to rapid weight loss in the short term, especially when the diet is very low in calories.
However, you could experience some negative health consequences of such severe calorie restriction, especially if you follow the diet for more than a few days at a time. Some of the health consequences are Reduced Metabolism, Inadequate Fiber, Nutrient Deficiencies, Increased Risk of Infection, Fatigue and Weakness and Reduced Lean Muscle Mass
Additionally, it is difficult to sustain such restrictive diets. Most people do not stick with very-low-calorie diets for long, and end up gaining back the weight they lost.
Juicing may be an easy way to lose weight quickly, but it appears that its potential health consequences may outweigh its benefits.
You are better off following a more sustainable diet that includes whole foods and enough calories to keep your body functioning properly.
