Be accountable to your exercise regiment

Designate a day during the week (generally in the beginning of the week), where you jot down your exercise goals on a calendar. Most cell phones nowadays come equipped with built in calendars (with "reminder" functionality). Record your weekly goals there. Sometimes last-minute plans get in the way of course, but recording it on your schedule will make you much more accountable.

Initially Count calories

When you count calories, you begin to realize just how many calories that you consume on a daily basis. So tracking what you eat can help keep you aware of what you are putting in your body. One of the more comprehensive calorie trackers is MyFitnessPal Calorie Counter. After you get a grip on your calorie intake, merely track what you eat, and remain accountable.

Incorporate Fresh Fruit With Your Breakfast

Seems like a small thing to do, but it sets a healthy tone for the rest of your day. Plus, fruit is low in calories and good for you! Make sure that you keep track of the amount (and type) of fruit that you intake, as some fruits can be high in sugar.

Reduce Portion Sizes

Of course, eating less of your usual servings will undoubtedly help you lose weight. Once your body gets comfortable with the reduced portion sizes and you are not as hungry as you were before, you will achieve "portion control." Just remember, eat enough to be satisfied, not full.

Read Health and Fitness Magazines

These types of magazines are filled with images of men and women who have the body types that you may desire to achieve one day. This serves as constant motivation, and it keeps healthy eating and fitness interesting. They are also filled with tons of a great ideas for meals and workouts.

Create a Meal Plan

Similar to the exercise plan, pick a day at the beginning of the week and sit down and plan a week’s worth of meals. Make your own lunch instead of buying; that way you have more control over how many calories are in your meal.

Keep Truckin’

Maintaining a healthy weight is all about balance. If you overindulge at a weekend barbecue or mindlessly munch throughout the afternoon, don’t throw in the towel. Make sure that your next meal is healthy and move on.
