First, congratulations on losing 10 pounds already and getting a job which keeps you on your feet. You have a made a great start!
Everyone has already made good suggestions. I can relate to your plight because I was there for many years; wanting to lose but staying in the same cycle of craving and caving. Glory87 talked about how eliminating the sugar really helped lessen the cravings. I totally agree. After many years of trying, it actually became so much easier once I eliminated sugar and white flour from my diet. Reading books really helped me to begin to understand alot of the components. "The End of Overeating" by David Kessler really opened my eyes to the physical component of food addiction.
http://www.theendofovereatingbook.com/blog.php Once I understood how my body responded when I ate sugar, fat and salt, it became easier to avoid the foods that seemed to overpower my personal desire to lose weight. I went ahead and followed a specific plan for detoxing from the sugar addiction which was difficult. After 2 weeks, I felt much better and it was much easier to stay on track.
Exercise has been mentioned, and I found it helped me lots, too. I have found exercise I like (bike riding and water aerobics) which make it easier to stay consistent. If you're not quite ready to start a formal exercise routine just start walking an extra block or 2 every day. I always park at the far end of the lot when I go to the store.
Another poster mentioned the Beck books. I highly recommend reading them, too. I have just recently read them and am incorporating Dr. Beck's principles into my food plan. Here is a link to the forum at 3fc;
http://www.3fatchicks.com/forum/beck-diet-solution-234/ .From the forum, "The Beck Diet Solution is a psychological program, not a food plan. It provides a step-by-step program to learn specific techniques to stay on our diet, lose weight, and maintain our weight loss for life. The program is based on Dr. Beck's clinical research in Cognitive Therapy (CT)."
I noticed your goal to reach onederland by the time classes start again. You have a very realistic goal in sight. I would suggest that you simply start by;
1. Committing not to regain the weight that you have lost. If you simply add some exercise, and start making better food choices right away you can maintain your current losses while you formulate a strategy.
2. Start reading, and learning about different food plans. I find that planning is a key to success.
3. Find a forum here that you can call "home" and post every single day. When I post every day, I find that my bad days are less likely to turn into bad months.
4. You have some great reasons to want to lose weight. Write them on paper and read them every day. It helps!
Give yourself a big pat on the back for being concerned about your health and bringing your questions here. Don't give up, keep striving to break the cycle of weight gain. You can do this!
Best wishes!
