Adding juices to this plan is the best way to achieve a healthy and sustained weight loss with the 5:2 diet.

The 5:2 diet is similar to intermittent fasting. It proposes five days with the freedom to eat what you want and in the remaining two, you eat fewer calories or do a juice cleanse. It’s very simple and you don’t need macro calculators and boring time-consuming methods.

What is The 5:2 Diet And How Does it Work?

This popular alternative of intermittent fasting consists of maintaining a very low-calorie diet (about 500 kilocalories) for only two days a week (any days you choose or any days that are easier for you to consume this much) and the rest of the days (5) eating normally and without restrictions, only focusing in consuming healthy and balanced meals and snacks, avoiding ultra-processed foods such as pre-packaged snacks and high in sugar foods.

On the days you have to reduce your calorie intake you can follow a special juice plan, specifically designed for this diet. Below you will see what you need to have in mind when it comes to choosing the juices you will be drinking during these days.

A 52 Juice Program

What You Need To Look Out For In 5:2 Juice Program

We think that fruits and vegetables have the power to heal us from the inside out. Thus, there’s no better way to replenish our nutrients and energy for the days we need to consume fewer calories than by adding juices to our weekly routine and our diet.

Adding a good quality juice is a great way to add a nutrient-packed and delicious alternative that provides the vitamins and minerals we need, but that at the same time does not add up too many calories. There’s nothing better than this than a good cold-pressed juice, specifically designed for lower-calorie diets whilst ensuring you are receiving all the nutrients your body needs to function properly.

For this you need to ensure that your juice has the following properties: 

  1. It should not contain too many calories.
    This may sound a little counterintuitive, as people tend to think that juices don’t have too many calories, but you’d be shocked to hear some juices can contain more than 500 calories per glass! So, it’s important to choose a juice that does not contain calorie-dense fruits in it. With the Plenish’s 5:2 diet, you get 628 calories of nutrient-packed juices every day. 

  2. It should not have added sugars or sweeteners.
    Why? It provides extra and empty calories. Meaning that they do not have any specific extra nutrients. It’s even worse. Besides, a recent study published in Cell Metabolism shows that artificial sweeteners (even the zero calories ones) can increase sugar cravings. So, better safe than sorry. Each Plenish juice contain only organic fruits and vegs – without the use of sugars or sweeteners. 


  3. It has to be tasty and organic.
    Why tasty? Well, you want to stick to a diet plan, it might be harder to do this with a not-so-tasty juice, why not treat yourself and have the best one you can find? We do the work for you, we test, we try and we deliver!
    Why organic? No doubt reducing our carbon footprint, supporting the local economy, eating fresh food that is in season, knowing where it comes from and how it is produced are all positive aspects. Plenish is Soil Association Certified – their cold pressed juice is made from the finest organic produce. 

By introducing organic produce, you’re ensuring that there are no agrochemicals, pesticides, or unwanted substances in your food. This also means that the soil receives proper nutrition, so it contains many nutrients. Our top picks are made with the highest quality produce, grown without pesticides, and naturally high in antioxidants.

What Results to expect From starting a 52 Diet

What Results Can You Expect From a 5:2 Program?

The 5:2 program is the ultimate way to hit your weight loss goals fast. It’s easy, you just need to drink our juices 2 days a week, and use these to substitute food with delicious and carefully picked cold-pressed juices. By doing this simple shift in your diet only twice a week, you cut down your calories to 500 per day! That means that you can achieve a healthy and sustained weight loss.

The program helps reduce your caloric intake, resulting in weight loss. It also helps decrease fat storage and cuts cravings and appetite whilst keeping you fuller for longer and not feeling restricted.

A question that comes up often is – How much weight can you lose with an intermittent 5:2 fasting diet?

When we consume calories, many of these are burned during digestion and other processes the body carries out to keep us alive, including organ function, breathing, moving, thinking, and talking. However, when we consume extra calories the body uses it as fat for storage in case you starve. To lose weight, you have to burn more calories than you eat.

It’s worth mentioning that drinking juices alone won’t make you lose weight but it can help keep you fuller for longer with fewer calories, or to replace calorie-heavy foods a few days a week, as we do in the 5:2 diet plan, thus achieving the calorie deficit we need to burn fat and lose weight.

By following this program you might lose around 2lb to 5lb and going up, depending on how long you keep it going. Yet, it will depend on several factors such as your age, sex, weight and height, hormones, and level of activity.
