1. Drink plenty of water or other calorie-free beverages.
   People sometimes confuse thirst with hunger. So you can end up eating extra calories when an ice-cold glass of water is really what you need

2. Consider whether you're really hungry.
   Whenever you feel like eating, look for physical signs of hunger ,hunger is your body's way of telling you that you need fuel, so when a craving doesn't come from hunger, eating will never satisfy it.Keeping your portions reasonable will help you get more in touch with your feelings of hunger and fullnes.

3.  Be choosy about nighttime snacks.
   Mindless eating occurs most frequently after dinner, when you finally sit down and relax.Sitting down with a bag of chips or cookies in front of the television is an example of eating amnesia, where you mindlessly eat without being hungry, but out of habit.Once you find that you're usually satisfied with the low-cal snack, try a cup of zero-calorie tea

4. Enjoy your favorite foods.
   Instead of cutting out your favorite foods altogether, be a slim shopper. Buy one fresh bakery cookie instead of a box, or a small portion of candy from the bulk bins instead of a whole bag. Putting your favourite foods leads to weight gain because it triggers 'rebound' overeating.You can enjoy your favorite foods, but you must do so in moderation 

5. Eat protein at every meal.
   Protein is more satisfying than carbohydrates or fats, and thus may be the new secret weapon in weight control.Diets higher in protein and moderate in carbs, along with a lifestyle of regular exercise, have an excellent potential to help weight loss.Getting enough protein helps preserve muscle mass and encourages fat burning while keeping you feeling full. So be sure to include healthy protein sources, like yogurt, cheese, nuts, or beans, at meals and snacks.

6. Spice it up.
   Add spices or chiles to your food for a flavor boost that can help you feel satisfied..Because food that is loaded with flavor will stimulate your taste buds and be more satisfying so you won't eat as much.
