You’ve probably heard of the SlimFast diet, but have you tried it? We’ve got all the information you need to decide if the Slim Fast diet is for you plus expert advice.
The SlimFast diet has to be one of the most well-known diets around – which isn’t surprising when you consider that it’s helped thousands of people lose weight over the past three decades.
The plan is known as one of the diets that work fast, while encouraging healthy and steady weight loss. In fact, in our SlimFast review, our tester Sarah explains how she lost an incredible five stone on the plan. But what is SlimFast, and how can you use it to get equally great results?
What is SlimFast?
The SlimFast Plan is built around a selection of meal replacement products, low calorie meals and a variety of snacks, like bars, pretzels and porridge.
Each SlimFast meal is nutritionally balanced so you don’t have to take additional vitamin supplements, unlike many other diets. SlimFast is good for people who lead busy lives or who often eat on the run – because the meal replacements are pre-packed, there’s no need for weighing portions or counting calories.
How does the SlimFast diet work?
The SlimFast plan is really easy to follow – it’s said to be ‘as simple 3. 2. 1’, because each day, you can eat three snacks, two meal replacement shakes or bars, and one healthy 600 calorie meal per day (or 800 calories for men).
The SlimFast plan is designed to deliver between 1,200-1,400 calories per day for women and 1,600 calories a day for men. This creates a calorie deficit of around 600-800 calories a day, so you should experience a steady weight loss of around 1-2lbs per week.
In addition to eating up to six times a day, you’re also encouraged to drink plenty of water, and take up regular exercise.
What are the drawbacks of SlimFast?
The plan is portion controlled, so if you’re used to large portions you may struggle during the first few days.
If you’re eating out in the evening or celebrating a special occasion, you’ll also have to try and keep within the 600 calorie limit, or miss out a few snacks in the day to allow for the extra calories.
Nutritionist Rob Hobson explains that whilst SlimFast is a great option for some people to lose weight it’s still essential to enforce healthy eating habits.
‘My only problem is that it’s not ‘real food’ so you need to learn to understand what it means to eat well in order to avoid yo yo dieting.’
Rob adds: ‘The positive of a SlimFast diet is that it’s calorie controlled and everything is given in the right portion size so it’s all managed for you. The shakes are also fortified with vitamins and minerals however they are low in cals so you might find yourself feeling hungry!’

‘SlimFast kickstarted my weight loss!’
Alex Vanstone lost 2 stone following the SlimFast 3.2.1 Plan. Last year Alex took part in the Channel 5 TV show ‘Lose a stone for Christmas’ where she was asked to trial the SlimFast plan. Alex says: ‘My main reason to go on the show was to give me a real push to kick start my weight loss plus I was sick of being the dumpy one in my group of friends! My clothes were too tight and I was constantly paranoid of how I looked. I’m not lacking in confidence but felt I was holding back a lot due to how I felt. I’ve always struggled with my weight and I’ve pretty much tried everything out there, however SlimFast wasn’t one of them till the show. I had several misconceptions about the brand and once I’d looked into it I felt very confident and was eager to get stuck in.
The plan was simple and effective, I started seeing results quickly! The ready to drink chocolate shakes are my favourite, they keep me full and I love the fact that they have all the vitamins & minerals my body needs. SlimFast has been a game changer for me, its taught me about portion size and the importance of eating a good mix of healthy & filling foods.
In total I’ve lost a total of two 2 stone and couldn’t be happier. I love that people notice and there’s no better feeling than someone telling you that you look great! (If only we could bottle that!)
During lockdown I’ve definitely had more ‘snack-cidents’ than I would like to admit! With the kitchen fully stocked it’s hard not to make a few extra trips to the ‘treats’ cupboard. SlimFast gives me the routine and structure I need to keep me on track when I need it. I certainly don’t want to slip back to where I was before. I can just imagine how disappointed I’d feel to have undone all my hard work. Losing the weight gave me the confidence to embark on a new career – it’s literally given me a new lease of life and I wouldn’t give that up for anything! So now that lockdown is easing I’m starting to up the exercise and reduce my trips to the snack cupboard!’
