“Not been on them long but have already lost 2 1/2 stone. I have a shake for breakfast made with milk, a shake for dinner made with water and a healthy meal for my tea. These are the only thing I have found to keep me full and not feel hungry”

“I started the slim replacement shakes on 17th March 2025 and have lost 3.5 stone on 17th August 2025. They are an amazing tool to help on a weight loss journey along side a calorie deficit. They taste amazing and so convenient to make up for a lunch time at work . They are a way of life for me now and love all the flavours. Come on girls you too can do it 💪”

“Really enjoying my journey with the shakes. I have lost 1 stone 3 lbs in 6 weeks. Raspberry & white chocolate, mint chocolate chip, vanilla, banana & lemon curd are all great! Strawberry & chocolate next! The coffee shot in my morning vanilla shake is my favourite!”

“Tried the banana flavour first, and I was sceptical about mixing it with water. I was pleasantly surprised, It tastes just like the shakes you get from fast-food restaurants! Even better, I make it right before and leave it in the fridge. When I take it out, I give it a quick shake, and it’s so tasty. I have a terrible sweet tooth, so this really helps satisfy my cravings. I’ve recommended it to friends, and they’ve purchased it too. I’m really enjoying it, and the weight is coming off as well!”

“I’ve bought 4 flavours and my preference in this order are 1. pineapple & coconut, 2 raspberry & white chocolate, 3. Mango tropical, 4. Strawberry cheesecake. The strawberry cheesecake one is nice but a very mild flavour in comparison to the others. 1st week lost 1.5lbs (but I’d been out for two birthday lunches), 2lb the second week and just coming up for the third weigh-in in a couple of days so 🤞🏻”
