Juicing involves extraction of juice from fruits and vegetables.
The liquid thus obtained contains most of the vitamins, minerals and other nutrients that are found in the food, except the fiber and solids mass.
A typical juicing process requires the fruit or vegetable to blend in a blender or juicer by removing inedible seeds and peels and then straining through a strainer to separate the juice from the solid masses.
A liquid drink is obtained which contains most of the healthy ingredients of the food.
However, this process removes the healthy fiber from the foods which make these drinks less satiating.
Another way to gain this fiber is to try blending the foods without straining them or by adding the pulp (solids) to another dish.
Juicing is particularly useful for persons who are averse to eating whole fruits and vegetables.
For such people, juicing of these foods provides an excellent way to obtain the nutrients and health benefits found in fresh fruit and veggies.
But can juicing help one lose weight? Let us find out.
Can Juicing Help you Lose Weight?
The answer is yes, juicing can help in weight loss.
Research says that consumption of more fruits and vegetables along with physical activity and self-monitoring had longer weight loss effects of up to 12 months and may be beneficial for long-term weight management.
Consumption of fruits and vegetable juices has been recommended by various studies to promote weight loss.
Research also advises that the daily intake of low-sodium vegetable juice along with a low-calorie diet can be an efficient and easy way to lose weight for obese individuals.
Here are the many ways in which juicing can be beneficial for weight loss.
1. Juices hydrate the body
Juices can contain about 80-95% water depending on the fruit or vegetable.
Thus, by consuming these liquids, one is also taking lots of water which hydrates the body and helps in its normal functioning.
Consumption of plenty of water has been associated with weight loss. According to a study, drinking unsweetened and non-caloric water like 100% fruit juice (free from added sugars) daily of a quantity more than 1 liter can amount to a significant reduction in body weight and fat mass over time.
Thus, one can replace some glasses of water with juices daily to facilitate their weight loss process.
What does this mean? Most juices contain lots of water and drinking more fluids can reduce food intake and promote loss of body fat and mass.
2. Juices influence gut microbiome
Intake of juices from fruits and vegetables can affect the composition of gut bacteria which are associated with the development of obesity.
Studies have linked obesity with alterations in the gut bacterial populations.
When 24 adults were examined for changes in body weight and BMI after consumption of vegetable/fruit juices for three days, differences in the number of intestinal bacteria and weight loss was reported.
What does this mean? Juices from fruits and vegetables can modulate gut microbial populations, which can result in weight loss.
3. Juices decrease the body fat
Fruits and vegetables usually have very few calories, and their consumption does not increase glucose or lipid levels in the body.
Thus, there is no fat formation and weight gain.
In studies, consumption of fruits and vegetables resulted in lower adiposity or body fat levels and slower weight gain.
What does this mean? Juices are usually fat-free and great foods to include in a weight loss diet. They also lower body fats and delay weight gain.
4. Juices can displace high fat and high-calorie foods from the diet
Some high-fat, high-sugar and high-calorie foods from the diet can be replaced by juices.
By consuming more liquids, one can limit energy intake and other types of foods which could contribute to weight loss.
Using this hypothesis, a study was able to prove that reduction in energy and fat intake brought about by increased vegetable and fruit consumption resulted in weight loss over a three-month period and prevented weight regain in the long run.
It is also possible to curb one’s craving for sweets with fruit juices as they contain less sugar than any other sweets and desserts.
What does this mean? By drinking more juices, one is creating lesser space in the stomach for other high-fat for high-calorie foods. This decreases energy and fat intake and prevents weight gain.
5. Fruit and vegetable juices are rich in antioxidants
Most of the fruits and vegetables used for juicing are rich in different types of antioxidants like vitamins, resveratrol, anthocyanins, carotenoids, polyphenols, and flavonoids.
These antioxidants help in scavenging free radicals and toxins from the body and can fight them or neutralize them.
As a result, the body is spared of various diseases including obesity.
Studies have shown that obesity and oxidative stress (surge of free radicals) are related. Oxidative stress can lead to weight gain, obesity, and related disorders.
By consuming antioxidant-rich juices, radical oxygen species can be taken care of, and obesity can be prevented.
A study found out that consumption of mixed fruit and vegetable juices for about a month led to a significant increase in serum antioxidant levels.
In another study conducted on 15 obese women for two months, intake of fruits resulted in improved antioxidant status and decreased cholesterol levels.
What does this mean? Antioxidants help fight the free radicals that play a crucial role in the development of obesity. Fruit and vegetable juices are excellent sources of antioxidants.

Some Tips for Great Juicing!
Always consume fresh fruit and vegetable juices as keeping them for long hours can lead to bacterial contamination. Microbes tend to grow easily in juices as they have the optimum amount of water and nutrients.
If consuming bottled or canned juices, opt for branded and organic products free from added colors, preservatives, and flavoring agents.
Look out for 100% fruit juices, free from added sugars. Some juices contain lots of added sweeteners which can spike your blood glucose levels and do more harm than good.
It is always better to consume whole fruits and vegetables rather than juicing them. The fiber in fruits and veggies can be more beneficial for weight loss as it makes one feel full and decreases food intake. Juicing is for those, who for some reason are unable to consume whole foods.
As liquids and juices are less satiating than whole foods, one may need to consume larger quantities of these fluids.
Combinations of fruit and vegetable juices or fruit cocktails can be made to increase the flavor and taste.
Juicing a fruit or vegetable removes its fibre but preserves many other nutrients like vitamins, minerals, antioxidants, and other functional components.
Juices have high water content and low-fat content.
They can decrease body fats and displace other unhealthy foods from the diet.
They can also influence the microbial populations in the gut, beneficial for weight loss.
Fruits and vegetables like apples, oranges, lemons, pomegranate, pear, spinach, asparagus, cherries, goji berries, elderberries, cranberries, and grapefruit are some of the foods which are excellent for weight loss.
