Slimming World

 By Mizpah Matus B.Hlth.Sc(Hons)


Slimming World is a long-established UK weight loss company which has recently begun serving both the USA and Canada.

They operate a very successful weight-loss program as a weekly class for members as well as an extensive online program as well as publish a magazine entitled Slimming World.

The Slimming World Diet is based on its diet plan centered around their concept of “Food Optimising“.

 All trade marks mentioned in this article are the property of the registered proprietor.

Food Optimising Plan

The Slimming World Food Optimising Diet Plan promotes weight-loss through calorie restriction in the diet, but in a way that promotes satiety and not starvation.

The Optimising Diet is based on these principles:

  • Nutritious or filling foods having a low calorie content are termed “free foods” (that is, the quantity consumed is unrestricted).
  • Some higher-calorie foods containing plenty of minerals, vitamins, or fiber are limited to 1 portion per day.
  • Other high-calorie foods like cheeses are measured and eaten according to the meal plan provided.

For a better understanding of how food optimizing works, they have a free 7 day menu published on their website.

Body Magic Exercise

Exercise is an important part of Slimming World. However, they realize that exercise is difficult for some people, so they emphasize the importance of starting small and gradually increasing activity as strength increases and weight comes off.

Members are encouraged to regularly do 5-10 minutes of activity by starting off small — for example, just walking down the driveway or to the end of their street.

The ultimate goal is for Slimming World members to complete 30 minutes of exercise 5 times a week.

Built in Support

Slimming World recognizes that dieters can increase their chances of success drastically by having a support system in place.

Members are provided with a trained Slimming World Consultant that will answer questions, provide positive reinforcement, as well as offer suggestions for increased success on the diet.

Members are also asked to join a weight loss group either at their few centers in Texas, Canada, and the UK or online through their website member resources.

    I was thinking of joining, and tried the 7day free trial, but everything just semp to bloat me and struggled to go to the loo. so much food and i put on despite walking 4 mile a day, still bloated.

    I have lost 24lb in 12 weeks. I found it easy to follow, but you must eat and not skip meals. The starter pack that you get from your consultant is good, read it a few times over the weeks to fully understand it. I didn’t have that much to loose so only 10lbs more. One thing I will say is that you must prepare for the week, most recipes that I tried were east and tasty – especially the curries. Try it and go to a group, I know i stick to it and loose more if I stay at the weekly sessions.

  11. Nicki

    Hi im!! My partner didnt have a unhealthy diet as i dont do frozen food or takeaways i like to do everything from scratch, he was over weight due to over eating mainly and the doctor recommended he just reduce portion sizes.
    Not listening He has gone onto the slimming world diet but his weight is just yo-yoing i believe this is due to the unbalnce of the fat content as it is near non existant.
    Can you tell me if this diet is so good for you way nutritionists recommend 65g of fat per day for a 2000kcal diet????????
