The key is to have some healthy snacks ready when hunger hits. Instead of a 3-ounce 85 g bag of flavored tortilla chips calories , choose a cup mg of air-popped popcorn 31 calories , a cup mg of grapes and a low-fat cheese stick or a small apple and 12 almonds calories.

Choosing healthy snacks twice a day will easily save you calories. Cut one high-calorie treat. Try to remove one high-calorie food item each day. Whether it is a donut in the morning, a brownie or bag of chips at lunch, or chocolate cake after dinner, you will save to calories or more.

To burn another calories, take a minute brisk walk after lunch or dinner. Do not drink your calories. One ounce mL regular soda has about calories, and a ounce mL flavored latte can pack calories or more.

Even fruit smoothies have lots of calories, as many as in a ounce mL serving. A couple of sweet drinks a day can easily add up to calories or more. Choose water, plain or flavored, sparkling water, or black coffee or tea instead and save your calories for foods that will help you feel full.

Skip seconds. Taking a second helping can add up to unwanted calories. It is easy to keep filling your plate when you serve food family style on the table. Instead, fill your plate once and keep extras in the kitchen.

Or, if you still do not feel satisfied, add a second helping of vegetables, fruit, or salad. Make low calorie substitutions. Substitute lower-calorie options for some of your high-calorie favorites.

For example, if a recipe calls for a cup mL of sour cream calories , use plain low-fat yogurt or Greek yogurt instead calories. Ask for a doggie bag. The portions at most restaurants are much larger than recommended serving sizes.

Instead of cleaning your whole plate, ask the server to put half in a container for you to take home for another meal. You can also share an entrée with a friend, or make a meal out of an appetizer and a large salad.

Just be sure to go easy on the dressing and fried toppings. Just say "no" to fried food. Frying food adds lots of unhealthy calories and saturated fat to any dish.

Instead of fried chicken or fish, choose grilled, broiled, or poached instead. And skip the French fries. A large serving of fries alone can add almost calories to a meal. Instead, see if you can substitute for the vegetable of the day or a side salad. Build a thinner pizza. Skip the meat toppings, extra cheese, and deep-dish crust, and have a couple slices of thin-crust vegetable pizza instead.

You will save a little over calories. Use a plate. Eat all food from a plate or bowl, including snacks. When you snack out of a bag or box, it is easy to eat more than you intend to. This is especially true if you are sitting in front of the TV. You may be surprised to learn that a large bag of chips could be more than calories.

A diet that is based on less than calories a day is a very low-calorie diet. Low-calorie diets work by limiting the amount of calories you eat so your body doesn't take in more calories than it needs to and can use up.

And women need around 2, calories a day. But most people need different amounts of calories based on how their bodies work, how much they move, and what their weight management goals are.
