Everyone knows the keys to losing weight: Eat less and exercise more. Sounds simple enough, but in the context of real life and its demands, it can be anything but simple.

Best Diet Tip No. 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.

Best Diet Tip No. 2: Think about what you can add to your diet, not what you should take away.

Start by focusing on getting the recommended 5-9 servings of fruits and vegetables each day.

Best Diet Tip No. 3: Consider whether you're really hungry.

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.

Best Diet Tip No. 4: Be choosy about nighttime snacks.

Mindless eating occurs most frequently after dinner, when you finally sit down and relax.

Best Diet Tip No. 5: 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.
