Hi Laura,
I understand how you feel, I've felt the same way when I began my diet, but I assure you, as soon as you see results you'll start to get more and more motivated to continue. Here are a few tips, hope you'll find them useful:
1. Make a Vision Board - Make a picture board full of pictures that inspire you and will motivate you throughout your weight loss journey. Cut out pictures from magazine, write out quotes that inspire you, and other images that will motivate you. Take all of these items and place them on a piece of tag board or cardboard. Then glue or tape all of your things to your board.
2. Chart your weight loss progress. If seeing the numbers are motivational to you create an excel chart that maps out the progress that you are making. You can set up your excel sheet to track what is important to you. A few examples of things that you could chart in excel would be your weight loss, body measurements, calories eaten each day, amount of time working out each day, etc.
3. Avoid weighing yourself too often, or if you feel that you have to, use a Quantum scale, it registers your weight but does not display it, so you don't have to worry about developing any "scale anxiety". Remember, your scale is supposed to be a tool to help you manage your weight, not an evil device deciding your mood for the day.
4. Take a picture of yourself before you get started or in the first few weeks of your weight loss mission. Keep the picture with you and look at it whenever you are wanting to make a poor decision. When you look at it remind yourself that you do not want to look like that and remind yourself of the goals that you are working towards.
Good luck and keep us updated on your progress!
