Not from any UK seller we could verify on 13 October 2026. Here's what we checked, and when.

Overseas Optifast products are a different proposition. The Australian “VLCD” packs that occasionally appear on eBay are a different formulation with labels written for a different market. We don't recommend importing them.
Optifast was Nestlé Health Science's total diet replacement range, described by Nestlé as “developed specifically for medically supervised weight loss”. The UK line-up included shakes in six flavours, soups, bars and desserts.
On total diet replacement, the regime was four sachets a day. The UK data cards described the products as meal replacements for weight control or total diet replacement, labelled for adults only, and not to be used as total diet replacement for more than three weeks without medical advice.
Optifast was used in the NHS low-calorie diet pilot launched in 2021 for people with type 2 diabetes, and some NHS hospitals' pre-surgery diet leaflets named it alongside other meal-replacement and food-based options. It had a long clinical history and loyal users.
Side by side, the numbers are close. Both are meal replacements for weight control in the same regulatory category.

Where Optifast had the edge: a long clinical heritage, use in the NHS low-calorie diet pilot for type 2 diabetes, and gluten-free shakes. Where ours comes in: it's a plan you can actually buy today, with an app and a community that come free, from a UK food company you can email.

Some NHS hospitals' pre-surgery diet leaflets list Optifast as one of several options, alongside supermarket own-brands and milk- or food-based plans. Optifast was also used in a 2021 NHS low-calorie diet pilot for people with type 2 diabetes.
If a doctor, dietitian or surgical team gave you a plan, follow it, and don't change products without their agreement. They'll know which alternatives they're happy with, and that's the right conversation to have.
Every Shake That Weight plan comes with the MyJurnee app, free with every plan, plus our Facebook support group and a UK team you can reach by phone, email or live chat. The app covers weigh-ins and goal tracking with daily reminders, a private progress photo journal, an audio and written habit course, craving support and one-tap reorder, and it keeps running through maintenance.
Optifast's UK retail packs didn't come with a published app or coaching programme. If you were on the NHS low-calorie diet pilot or a bariatric pathway, your support came from the clinical team running it.
If you'd rather have real people to ask alongside a self-serve plan, that's what we're built for. If you need medical oversight, your GP or clinical team is the right place.
We have six plans, each with its own calorie bracket and purpose. Pick the one that matches where you are.
Total diet replacement is short-term and should be done with medical advice if you have a condition or take medication. It isn't for under-18s or during pregnancy or breastfeeding.
Shakes, soups, meals, bars and breakfasts, all portion-controlled and nutritionally formulated as meal replacements. On 13 October 2026, our in-stock range is:
Dietary options include vegetarian, gluten-free and vegan products, labelled on every product page — on 13 October 2026, 31 of our in-stock products are labelled vegetarian, 21 gluten free and 4 vegan. Shake flavours in stock include Vanilla, Strawberry, Café Latte, Chocolate Mint, Chocolate Hazelnut, Cherry Bakewell and Tropical.
We're not aware of an Optifast discount code anywhere — it isn't on sale from any UK seller we could find.

"Although I’ve already written a review. I had an issue with Royal Mail on the delivery with 23 items missing. I spoke with Natasha who resolved the problem immediately, sending out replacements and handling the issue with the Royal Mail. The customer service was second to none. Well done guys."
"I have written a number of reviews for STW and my views are still the same. Easy to place order, good communication and quick delivery. The shakes are tasty, filling and good value and do work if you keep on the plan. Excellent service for yet another order and still my go to diet for shedding the unwanted pounds. "
"Easy to use and tasty shakes "
"The website is great and easy to use. Delivery was good and quick. The products( I am Gluten free ).So many different options to choose from. Products are full of nutrients/ vitamins that the body needs and taste lovely. I highly recommend shake the weight and it so works if using for weight loss. 5 star "
"Excellent service with fast delivery thanks "
"They arrived well packaged and on time. The bars are bigger than expected and very filling. I haven't been hungry since using them. The taste is also superior to other bars I have used in the past. I particularly like the peanut ones and the chocolate cookie ones. I have lost over 3lb this week and have been having a sensible low calorie, low carb evening meal. I'm over 68yrs and had been finding it hard to shift the weight."
