Don't keep foods on hand that go against your diet plan. Clean out your fridge and cupboards when you start your diet, and give away anything you know you shouldn't eat. Stock up on good-tasting healthy foods instead. You won't find yourself tempted nearly as much if your forbidden foods aren't easily accessible.
You should look to having a leisurely meal with your family if you are watching your weight. Family time is always important, and sharing a lengthy mealtime with them will encourage less eating. It takes about 20 minutes for your brain to recognize that you are full, so longer meals lead to eating less.
Try to eat your dinner before seven o'clock in the evening. Doing that can assure that you will not be going to bed too soon after eating. This means that you will be able to burn off some of the calories and you will be able to get a better night's sleep.
