Food Optimizing is based on the science of satiety (how filling a food is) and energy density (how many calories per gram a food has). Free Foods are filling and low in calories—they keep us feeling fuller for longer, and naturally reduce calorie intake. This means you can eat them in unlimited amounts—and lose weight* without hunger or deprivation.

No food is banned at Slimming World, so the short answer is yes! We offer no false promises, though—for weight loss success, you will need to make changes to the way you shop, cook, eat and eat out, so you’ll likely find yourself choosing fruit, veggies, lean protein and grains more often.

There’s no calorie counting with Slimming World! By filling up on unlimited amounts of Free Foods, which are low in energy density and highly filling, you’ll naturally lower your calorie intake without counting a thing. To protect your weight loss and keep from feeling deprived, we ask members to weigh and measure Healthy Extras and Syns.
