Description

The 4 Week Challenge is a programme curated specifically for anyone looking to kick-start their weight loss journey and boost their health in a short span of time.

How it works
Our juices will get delivered to your door for your choice of 2 or 3 days per week, for a total of 4 weeks. On your cleansing days, you get to replace meals with the juices to get in the essential nutrients your body needs. This challenge makes it easy for you to reach your goals without worrying about the meal prep, planning and hassle that comes with dieting. You will get your juices weekly for 4 weeks on the same start day you select at checkout. Important: Select deliver once at the checkout and they will still be delivered weekly as this is not a subscription product!
 

A Flexible Plan

If you ever wish to pause the program or switch out any of the juices due to boredom, we will always accommodate your request if you let us know prior.

Lose it, Keep it off

This challenge allows you to lose weight whilst doing the cleanse, and continue to sustain it after. Your cleansing days are curated by nutritionists to incrementally rewire your brain to stop craving unhealthy, processed foods. 

Cost-Effective

It is also a cost-effective option compared to purchasing individual cleanses. With its combination of affordability and health benefits, it's a win-win situation for those seeking a healthier lifestyle.

It is definitely true to say that our bodies cleanse naturally and constantly. We like to think of our juice cleanse program as an occasional way to pause and reflect from hectic normal life routines—and to take a dietary choice with us. Historically cleansing was a way to bring balance back into people’s lives. So, while it is only being incorporated into dietary practices in the past few years by the masses, cleansing is certainly not a trend.

In our minds, adults can benefit from a cleanse program as a regular part of their lifestyle regimen but no more than once a month. Whether you are a stressed out workaholic or a stay-at-home mum, the truth is that life is no longer as simple as it once was. We are all busy and struggle to find time for ourselves and often our health suffers as a result. Presscription Juice cleanse programmes are designed for adults to enjoy, even those of you who are lactose-intolerant and keep a vegetarian or gluten-free diet. Children under 18 should not participate in our cleansing program. **Please keep in mind that our cleanse programs are NOT appropriate for those of you who are pregnant, breastfeeding, or suffer from certain medical conditions. Consult your health care provider before starting a cleanse program if you have a medical condition or take medications. Please see questions 3 & 4 for more information.

Our cleanse programs are designed for all healthy people; however, there are certain individuals who should not partake. If you are pregnant or breastfeeding, you should not restrict your diet to liquids, as you need extra calories and nutrients in your diet. Consult your health care professional if our drinks are right for you.

The answer to this is variable. Your body knows what to do, so trust it. We try not to focus on weight loss as a goal at Presscription, but we understand that it is important to a lot of people. You might also find that the cleanse actually prompts your body to re-balance itself.

Definitely, just try to be gentle with yourself. You are still getting nutrition, but it is wise to beware of lower volume of foods. You will most likely find that you have lots of energy and if you so desire, go for a light jog or power walk around the neighbourhood. Otherwise it’s always a great idea to stick to yoga or pilates for that added effect of intense breathing to help you maximise your cleanse.

We are totally for adding extra drinks if you feel you are in over your head with just 5 drinks and 1 almond drink per day, but make sure they are healthy! Stay away from carbonated drinks, especially soda, please! You are more than welcome to add extra doses of water with lemon and herbal teas. And if you would like to order extra juices from our site to keep on hand for emergencies, feel free to go ahead and do so.

Great idea

I’ve done one week of the 4 week challenge and looking forward to progressing each week. I haven’t managed a day yet with just juice as I have always snacked on fruit and nuts so hopefully by my last week I will be able to Manage a full 2 day cleanse

Mixed feelings

I did the 7 day gut cleanse first and then followed up with the 4 week challenge. The delivery service is excellent, the juices are tasty and I my sugar cravings are much reduced. I am experiencing consistent weight loss at around one pound a week, which is pretty good considering I am post-menopausal. I would recommend this programme.

4 Week Challenge

I’ve just completed my first week of the four week challenge. The juices taste great and although I had less energy on the first day, I felt much better on the other days. Eating well on the days when I’m not on the challenge is also much easier.
