For a better chance at long term success, make gradual changes to your lifestyle and dietary choices. You didn't pack all the weight on in a month, it's not going to come off and stay off in 30 days either.

Keeping track of what you eat/drink (particularly portion size) and when, not necessiarily your calorie intake, over the course of 4-7 days is information that you can use to learn about behavior.

Fall is a great season to start walking around the neighborhood. You don't need to go for an aerobic session, just start out with 10-15 minutes each in the AM and PM. Longer times and distances will develop naturally.

Calling something "rabbit food" isn't going to help you. However, substituting a side salad for fries or chips, or doing a few dinners without complex carbs like bread or pasta, isn't torture.
