Food Optimising is Slimming World’s healthy eating plan. Based on the principles of energy density and satiety, Food Optimising empowers members to make healthier food choices, satisfy their appetites and lose weight – without calorie counting or obsessive weighing and measuring.
Food Optimising is easy to follow, focusing on three main components:
- The concept of Free Foods promotes consumption of plenty of low energy dense and highly satiating foods, eg poultry, fish, lean meat, pasta, grains, vegetables and fruit, which can be eaten without restriction. Members are encouraged to use these foods to satisfy their appetite while reducing overall energy intake. With Free Foods members don’t have to monitor every mouthful – so compliance is easy to establish and sustain.
- Healthy Extras help provide a good overall balance of nutrients in addition to those obtained from Free Foods, with particular emphasis on calcium and fibre-rich foods, eg milk, cheese, cereals and wholemeal bread.
- The synergy between Free Foods, Healthy Extras and Syns makes Food Optimising effective and easy to live with long term. Syns are the way members can enjoy the foods that many diets ban – without a shred of guilt! Counting Syns helps members naturally limit consumption of saturated fats, alcohol and sugar, ie those foods with a high energy density and poor ability to satisfy hunger.
The science behind Slimming World's Food Optimising
Research has shown that the nature and composition
of the foods we eat, dietary macronutrients and energy
density, impact on our sense of satisfaction and
fullness (satiety) . Encouraging a higher intake of more
satiating foods will limit energy intake and result in
weight loss. Slimming World has been actively involved
in this field of research and, along with the Scottish
Office, sponsored research conducted by Dr James
Stubbs at the Rowett Research Institute. There is now
a robust evidence base which shows that foods higher
in protein and carbohydrates are far more satiating than
foods rich in fat .
Research also shows that people feel full due to the
amount of food they eat, not the number of calories they
take in. Choosing low energy dense foods can increase
the volume of food eaten, while reducing energy intake,
and thus satisfy appetite .
Since its inception over 45 years ago, Food Optimising
has always successfully embraced the scientific
principles of appetite regulation and energy density
in a practical way to regulate energy intake, allowing
members to eat unlimited amounts of highly satisfying
foods, which will naturally help limit calorie intake
without the chore of counting or feeling deprived.
A balanced approach
Through the structure of Free Foods, Healthy Extras and Syns, Food Optimising provides a flexible and practical weight loss plan whilst also encouraging a balanced approach in line with current healthy eating guidelines.
Food Optimising promotes a reduction in fat, particularly saturated fat, and the inclusion of at least five portions of fruit and vegetables per day alongside starchy carbohydrates and lean protein rich foods to satisfy the appetite. Measured portions of fibre and calcium rich foods are included on a daily basis.
All major food groups are encouraged in line with the Eatwell Guide1 and health notes guide members in following current Government recommendations on healthy eating. :
Around 88% of the Eatwell guide is
made up of a combination of fruit and
vegetables, starchy carbohydrates like
rice, pasta and potatoes and protein
rich foods such as lean meat and fish.
All of the eating plans encourage these
foods (sometimes in varying quantities)
and fruit and vegetables are always
Free Foods. A smaller section of the
guide is for milk and dairy. Food
Optimising classifies milk and cheese
as 'Healthy Extras', and encourages
those following the eating plan to enjoy
daily measured portions as they are
good for overall health. The smallest
purple section and those foods outside of the main image are
foods that are
high in fat or sugar - these are Slimming
World's controlled Syns.
Realistic and flexible, Food Optimising:
- takes into account individual needs and preferences
- adapts to all lifestyles, cultures and budgets,
and is suitable for all the family
- encourages slimmers to feel free and relaxed about
food, eliminating the distress caused by feelings of guilt, hunger, deprivation and loss of control
- enables members to take control of their own health and lifestyle for the long-term
- doesn't ban foods or food groups
- doesn't use expensive or specialist 'diet' products
