If you’re completely new to Slimming World, you’re likely to have lots of questions. We feel like ‘how does Slimming World work?’ is a good place to start. Read on to discover the ‘1, 2, 3’ of our expert weight loss plan, and how it can work for you.

1. A healthy no-hunger plan 

The first thing to know about Slimming World is that you’ll never feel hungry. Our delicious eating plan, Food Optimising, has been expertly designed to be flexible, fuss-free and to work for all dietary requirements and preferences. At the heart of Food Optimising is a focus on Free Food – healthy, satisfying food that you can eat in unlimited amounts. 

Slimming World Free Food

There’s a long list of Slimming World Free Food that you can eat to your heart’s (or stomach’s) content. Fill up on:

  • lean meat and poultry
  • fish
  • eggs
  • dried pasta
  • rice
  • potatoes
  • fruit
  • veg
  • some fat-free dairy products
  • some meat replacements (like plain Quorn and tofu)

As long they’re cooked without fat or oil, you can eat Free Foods until you feel satisfied, with no weighing, no measuring and no limits.

Many store-cupboard staples are also Free, making it easy to cook up a storm in the kitchen without worrying about it affecting your weight loss. Slimming World members will find more than 750 completely Free dishes in our online recipe collection, and that’s on top of lots of tasty Free recipes shared in group. We’re also full of ideas for how to make your foodie favourites completely Free, so you can have that roast dinner or cooked breakfast and still see the results that you want on the scales.

Slimming World Healthy Extras

To help provide a essential balance of nutrients, Slimming World members are encouraged to enjoy Healthy Extras every day. Healthy Extras are measured amounts of foods that are important for a balanced diet:

2 Healthy Extra ‘a’ choices to provide calcium – so milk and cheese (including dairy and non-dairy options)

1 Healthy Extra ‘b’ choice to provide fibre and other essential nutrients – so bread, cereals, crispbreads, nuts and seeds, and dried, canned and cooked fruit

Slimming World members have access to tools that let them search for and find the portion size for thousands of Healthy Extras. It’s not guesswork – it’s Food Optimising science!

Slimming World Syns

Another fantastic thing about Food Optimising is that no food is banned. The key is moderation, which is why alcohol and foods that are high in fat or sugar have a Syn value. Slimming World members are encouraged to plan 5-15 Syns a day to keep their weight loss on track, without feeling like they’re missing out.

Slimming World members can use our Food Search tool (online and on the Slimming World app), and the Food Optimising book in the new member pack, to find out the Syn values of thousands of different foods and drinks. That way, they can make informed choices about what they’re eating and drinking – Slimming World is all about choice power!

2. More ‘magical’ movement

Alongside Food Optimising, Slimming World members are encouraged to get active –  something we call Body Magic. It’s no secret that an active lifestyle brings lots of benefits (alongside giving weight loss a boost!), so building more movement into your day is a brilliant step towards a happier, healthier you. There are loads of different activities that count towards Body Magic – from walking and gardening to karate – and our Body Magic activity programme will help you get active at your own pace, in a way that fits in with your lifestyle, and, importantly, in a way that you enjoy.
