When starting the slimming world plan, you might notice that the syn allowance on the diet changes for men and women.
Women are allowed on average (depending on their weight) 15 syns a day, while men are allowed a larger syn allowance of 20 syns a day (once again depending on their weight.
To find out why men get a larger allowance of food with syns and why women get less, as well as how syns are calculated and what they count for with weight loss tips, we have put together our best guide below that will give you all the info you need to know.

Many people might argue it is not fair that men get more syns than women on the slimming world diet, and while this might feel true, it is all down to a science. Men are proven to need more calories to function even with weight loss goals, so will of course also have an extra syn allowance on the slimming world plan because they can eat more food.
By rule of thumb, men need 1800 calories for average weight loss success (very variable to weight) while women might be around the 1500 calories per day mark for weight loss depending on their weight goal and current starting weight.
As we have touched on above, syns do not only change according to gender, but they also change according to each male or females weight.
For example, men who weigh over 20 stone will get an allowance of up to 30 syns a day while women who weigh over 20 stone will get an online plan with a syn allowance of up to 20 syns per day.
This not to say a man has to eat all of his extra syns, as cutting back can be beneficial for weight loss efforts, so it is still safe for a man to stick around 15 syns if he wishes and limit his favourites foods.

You might be wondering how syns are calculated and made, to begin with, well, syns are made by judging food on its weight capacity and calorific value, so calorie-dense foods become high in syns such as oil.
High protein food and lean-meats foods are preferred on the online plan of slimming world as they fill you up fast and have great calorie allowances.
Syns allow you to enjoy your cravings from time to time in moderation without feeling restricted but are set by the slimming world so as it can still restrict calories for the basis behind weight loss goals.
We have a calculator which makes it convenient to enter the calories and it gives you the Slimming World syns.
Free foods on the slimming world plan are often lower-calorie foods types, for other foods on the slimming plan they have around 20 calories per syn, meaning one biscuit might have 80 calories which translates to 4 syns.
Once again, this proves why men can eat more syns and weight loss goodies because they have a higher calorie allowance in the slimming world and can still lose weight.

Syn values are calculated using a formula based on calories, saturated fat and sugar content per serving. They’re not the same as calories — a product can be low in calories but higher in syns if it’s high in sugar or fat. Always check the official Slimming World app for the most accurate and up-to-date syn values.
Yes. When manufacturers reformulate their products, the syn value can go up or down. This is why we recommend double-checking with the Slimming World app or your consultant, especially if a product’s packaging has changed recently.
Most Slimming World members work with 5 to 15 syns per day. Your consultant will advise on the right amount for you. The key is to use your syns on the things you enjoy most — whether that’s a chocolate bar, a glass of wine, or a packet of crisps.
