But for many people, that's easier said than done.
Here's a step-by-step guide to kick starting your rapid weight loss so that you set yourself up for success.
Step 1: Create a list of daily goals.
You might include the number of times a day you want to try to eat, that you'll stick to your daily food diary as hard as it can be at times, that you'll prepare foods a week in advance so you're ready to take on your busy schedule without having to think about your diet.
Try literally making these things into "To Do" lists so that you can check them off throughout the day.
Step 2: Devise a meal plan for the next week.
Actually plan out the foods you are planning on eating for each meal as well as for snacks.
Don't let yourself fall off your diet plans just because you haven't though out your meals and get caught with nothing to eat but fast food or cafeteria food.
Step 3: Go through your cupboards and refrigerator and get rid of those tempting foods that tend to sabotage you in moments of weakness.
Think about how you can re-stock your home with healthy choices that will make your body happy! After you come up with your meals for each day, write out a shopping list and stick to it.
Hit the grocery store and get yourself ready for the first week of the rest of your thinner, healthier life!
