Alcohol and carbohydrates are the elephants in the room here. My suggestion would be draconian...allow your tastes to be subjuct to your will, not the other way 'round. Stop at the pub? Drink tea or water. Don't purchase unhealthy snack foods or alcohol for [consumption] at home. Holidays come? Shrink portions of sugars and carbs. Make sure to maintain aerobic fitness during Winter. Sugars...no. Alcohol...no. Snack foods...no. Carb rich foods...no. Inactivity...no.
