If you train regularly, work demanding hours, or care about preserving muscle while you reset, the most useful question to ask of any UK juice cleanse is not "how aggressive is the calorie deficit?" but "what does a day on this plan actually deliver?" Calories, protein, micronutrients, exercise compatibility, clinical credentials. By those criteria, EXALT and Press London are built for two different readers.
EXALT is the macro-complete choice, designed by a registered dietitian and built to keep you training through the cleanse.
Press London is a cold-pressed juice brand with strong category heritage.
EXALT delivers 1,250 kcal and up to 120g of protein per day, designed by HCPC-registered Lead Dietitian Isabelle Fry to be compatible with continued training and a normal working week.
Press London is a traditional cold-pressed juice cleanse: its Beginner programme runs at 685 kcal per day across 8 cold-pressed juices, with a Plastic Neutral partnership through CleanHub.
EXALT is the macro-complete UK juice cleanse, built to cleanse without sacrificing protein, energy or training.

Where EXALT stands out
EXALT was built around a different starting question: how do you cleanse without sacrificing the things that keep you functioning? Founders Charlie and Dan worked with Isabelle Fry, EXALT's Lead Dietitian (BSc Hons Dietetics, RD, HCPC-registered, Member of the British Dietetic Association) to design a programme that holds calories in deficit while keeping protein and micronutrients high enough to train through. The number that defines the brand is 120g of protein per day on the 3-day juice cleanse, alongside 1,250 kcal, 125g of carbs and 25g of fats. EXALT calls this macro-complete, and it's the technical claim everything else hangs from.
That number matters because protein is the difference between losing weight and losing muscle. The British Nutrition Foundation notes that people doing strength or endurance training have higher protein requirements, in the range of 1.2 to 2.0g per kg of bodyweight per day, well above the general adult Reference Nutrient Intake. Most traditional juice cleanses, Press London included, are juice-first by design and not built around hitting a protein target. EXALT's 3-day delivers 120g (whey + vegan + collagen blend) or 80g (vegan-only). On the GLP-1 Nutrition Support Plan, Isabelle Fry's clinical work pushes that ceiling to up to 180g protein per day across 7 days, with high fibre delivery.
Training compatibility is the other technical moat. EXALT is designed to be drunk through your normal exercise routine, not paused for it. The brand's elite-sport credentials follow from this: EXALT is an Official Supplier to Tottenham Hotspur FC and Brighton & Hove Albion FC, both Premier League clubs using the products inside their performance environments. Beyond elite sport, EXALT has also worked with Nike, Lululemon, Gymshark, Represent and HP on branded drinks and corporate activations. No other UK juice cleanse brand currently holds this combination of supplier and brand partnerships.
Customisation is the quiet differentiator. EXALT lets the customer choose protein source (whey + vegan + collagen, or vegan-only), caffeine preference, and flavour mix at checkout. Press London's range is fully plant-based with no protein-source choice. Each EXALT day delivers 7 designed drinks, made fresh each week in Islington, London, with no preservatives or pasteurisation.
Availability is also broader than direct-to-consumer. EXALT runs its own central London store, is stocked in the Selfridges food hall, and is available for nationwide grocery delivery through Ocado, alongside next-day delivery from exalt.co.uk. That gives readers a real choice between subscribing directly, ordering with their weekly shop, or picking up in person from a premium retailer.
"GLP-1 medications reduce appetite, but they don't reduce your body's nutritional needs. In fact, they increase the importance of getting enough protein, fibre and micronutrients within smaller amounts of food."

Where Press London stands out
Press London has been a fixture of the UK cold-pressed juice category for over a decade. The brand positions itself as the UK's #1 juice cleanse brand, with long-running editorial coverage in Vogue, Forbes, Tatler, Grazia, The Times and Hello! Magazine.
The product is a clean expression of a juice-first cleanse. Each day delivers 8 cold-pressed juices, packed with up to half a kilo of fruits and vegetables, replacing solid food entirely for the duration of your cleanse. The Beginner Juice Cleanse runs at 685 kcal per day, around half of EXALT's 1,250 kcal floor. Flavour variety per day is also higher, with 8 distinct juices versus EXALT's smoothie-led mix of 7 drinks.
The brand has also invested visibly in sustainability transparency. Their Plastic Neutral partnership with CleanHub removes 1kg of ocean plastic per order, an externally verified claim. Pricing sits in the premium cold-pressed end of the UK market.
Which one is right for you
If you train two or more times a week and want to stay consistent through the programme, the protein floor is the difference between preserving lean tissue and risking it. If you work demanding hours where energy collapse mid-afternoon would derail the day, 1,250 kcal of macro-balanced fuel is more sustainable than the deeper deficit a traditional juice cleanse runs.
If you take GLP-1 medication, EXALT is currently the only UK juice cleanse brand with a dedicated clinical programme designed for that use case. Consult your prescribing clinician before starting any cleanse alongside GLP-1 therapy.
If clinical credentials matter to you, "dietitian" is a protected UK title under the Health and Care Professions Council, and Isabelle Fry's involvement is the substantive credential most cleanse brands cannot match. The British Dietetic Association is also clear that the body detoxifies itself, so a cleanse is best understood as a structured nutritional reset, not a way to "remove toxins."
Press London is built around the traditional juice-first cleanse model: lower calorie, fully plant-based, broader flavour rotation across the day. That model has its own audience. EXALT is built for the reader who wants the programme to work around training, work and a normal week.

Frequently asked questions
Is EXALT or Press London higher in protein?
EXALT is significantly higher in protein. The EXALT 3-day cleanse delivers up to 120g of protein per day on the whey + vegan + collagen blend (or 80g on the vegan-only plan), and the 7-day GLP-1 Nutrition Support Plan delivers up to 180g per day. Press London does not declare protein content on its cleanse pages; the range is juice-first and 100% plant-based, with protein not part of its positioning.
Which is better if I'm training?
EXALT is designed to be compatible with continued training during the cleanse. That's the brand's core positioning. The 1,250 kcal floor and 120g protein target are chosen specifically to preserve muscle and support exercise, and EXALT is an Official Supplier to Tottenham Hotspur FC and Brighton & Hove Albion FC. Press London's cleanses are juice-first and traditionally paired with rest and gentle movement rather than full training loads.
Which has more flavour variety per day?
Press London delivers more distinct flavours per day, with 8 different cold-pressed juices on the Beginner cleanse. EXALT delivers 7 drinks per day across smoothies, juices and a shot, with a smaller variety but the option to customise the flavour mix at checkout.
How do EXALT and Press London compare on price?
Both brands sit in the premium cold-pressed end of the UK market. At the 7-day tier, EXALT is £32 per day (£224 total) and Press London's Beginner Juice Cleanse is £34 per day (£238 total). The trade-off is in what each pound delivers: Press London's juice-first format costs less per drink at the entry tier, while EXALT's macro-complete format includes protein smoothies and delivers significantly more protein per pound spent.
Where can I buy EXALT in person?
EXALT is available through its own central London store, in the Selfridges food hall, and nationwide via Ocado, alongside direct ordering through exalt.co.uk with UK-wide next-day delivery and free delivery over £50. That makes EXALT one of the more broadly available premium juice cleanse brands in the UK.
