Can Drinking Alcohol Affect My Weight Loss On Slimming World?

Since alcohol is typically not recommended on most diets for weight loss, you might be wondering if having a few drinks could potentially ruin your progress on the slimming world plan?

Having alcohol in moderation on the SW plan will not affect your weight loss as long as the syns/calories fit your daily allowance, excess drinking, however, could put you past your 'tipping point' on slimming world which can stimulate your appetite and cause you to overeat.

We recommend alternating days on and off when drinking on the SW plan rather than saving all your syns for one or two days since this can encourage binge drinking.
