Syn Calculator 2024: Calculate Your Slimming World Syns Easily and Accurately

In Slimming World's unique weight loss approach, the term "syn," a contraction of "synergy," takes center stage. Syn values, which are attached to high-calorie foods, signify the need for moderate consumption. Every food item in the Slimming World program comes with an associated syn value, calculated through particular ratios and principles, with the higher syn value pointing to the higher calorie content.

For members to see substantial progress on their weight loss journey, adhering to the daily syn allowance — a crucial guideline provided by Slimming World — is paramount. The function and significance of syn in this program makes it a unique and essential component of successful weight management.

Calculating your syns from calories on the Slimming World diet plan can be tedious. Many people suggest that 20 calories mean 1 syn, however, this does not take into account the sugar/fats which are in food too, making a syns calculator useful and more accurate.

Your Slimming World syn allowance is not calculated to your specific weight but is more tailored to how much weight you have to lose.

How Many SYNS Can a Man Have?

For example, on average, the Slimming World diet suggests that for weight loss success, you can have an average of 15 syns a day, but for people who have more weight to lose, you might start with 15 then cut back to 10 syns or 5 syns a day to accelerate weight loss.

Many people tend to start on a high allowance of SYNS per day on the diet to ease themselves into the cut of calories, then reduce it slowly during their weight loss journey.

  1. Hi, I'm confused as your website states that sweet and sour mug shots are 13 syns per sachet but in two other places it states 1.5 syns?

  2. I'm getting so confused is it better to go with counting calories as in group we were talking about free foods having calorific values and how some people eat lots of these "free" foods and not losing weight,if still using s/w and syns how would you practise portion control
