Juicing entails squeezing juices from vegetables and juices, blending mixes all the edible parts, including the pulp. It helps in detoxification, a process through which your body gets rid of toxins, thus improving your health and helping you lose weight.

Cons of Juice Fasting

  • The juice may contain too much sugar, which may be detrimental to your health. In extreme situations, this may make your insulin resistance increase, leading to Type 2 diabetes.
  • Juices contain calories too, and thus there is still a risk of consuming high calories if you don’t maintain the right balance between your usual mean and the juices.

Is Juice fasting helping you significantly Reduce weight?

Many researchers agree that there are scant studies on the subject, but the few available studies acknowledge that a relationship exists between juice fasting and aid weight loss. Well-thought-out controlled studies have shown a reduction in weight on day three from the time the subjects consumed vegetable and juice-based diets. The researchers experimented on 20 people to see how their weight would change on the strength of the juice diet. The juices were a mixture of green vegetables, citrus, roots, vanilla almond, and cayenne. The subjects took 6 bottles of juice-based diet vegetable/fruit juices daily for three days. The weight decline remained significant over the following two weeks, which was attributed to microbiome changes. The diet was enough to induce changes in the intestinal microbiota, which is associated with weight loss. The research established that there were changes in firmicutes which are associated with increased body weight. The phylum Firmicutes levels went down, while Bacteroidetes spiked towards the end of day 4. Day four of the experiment registered a remarkable decline in body mass index, and this weight was maintained for the next two weeks. This shows that even three or four days of juice fasting can be beneficial to you. This shows juice fasting can work if done correctly. The study shows that you can lose weight through juice fasting because there were remarkable gains in weight loss. If you want to lose weight, then you can start to try juice fasting. Taking a variety of vegetable juices will be of enormous benefit to you. Juices from dark leafy greens and beets would particularly be good for this purpose. They contain polyphenols which may help in weight reduction.


UCLA has also recently attested to the benefits of juice fasting. According to the university, juice fasting reduces weight gain and promotes general wellbeing. UCLA established that eating many fruits and vegetables activates gut microbiota which determines how full or hungry you feel. They also help regulate the amount of energy your body absorbs. The microbiome instead acts indirectly in helping you control your body weight. In the grand scheme of things, lots of research has shown that people lose weight after juice fasting. However, the weight loss emanates from decreases in calories intake and changes in gut microbiota as opposed to specific juice characteristics.
