Hi camry07,
Thanks for writing and welcome to alli. The first thing that stands out to me is that you don't eat breakfast or lunch.... I don't know if that means you don't anything until and except dinner or if you eat some small snacks during your work day. If you do not eat until dinner time, you are surely sabotaging all of your efforts. Your body MUST have fuel (food= energy) to burn fat and calories. It is crucial to your metabolism to give your body enough energy to perform not only your exercise, but basic daily functions. If you are not eating enough, your body will hold onto what little you are feeding it in order to do the necessary metabolic needs.
You obviously have an unusual schedule that can be challenging when trying to eat on a regular schedule. Do your very best to eat every 3-3 1/2 hours getting in 3 meals (about 500 +/- calories each) and 2 snacks in-between (200 +/- calories each). It is important that you exercise, including cardio and strength training workouts. Do your best to get in 1hr or so of cardio (treadmill, walking, jogging, swimming, etc.) on most days of the week and perform 2-3 sessions of strength training (35+ min each session) at least 3 times per week. If you aren't familiar with strength training, look on the alli website at "myactivity" and click on "strength training log" to view animated full-body exercises.
You mentioned sleeping... it is crucial to your over-all health. Although you do not have a "regular" schedule, do your best to create one as best you can. You should not be working out 2+ hrs prior to falling asleep. Also, try to eat 3 hrs or so before sleep and create a cool, dark peaceful environment. Turn off all TV's and clear your mind before turning out the lights. All metabolic functions are seriously impacted during sleep, including those that are responsible for weight loss such as cortisol. If you continue to have sleep issues, talk to your doctor to see if he can suggest something to help.
Best of luck and keep up the hard work!
Kelli
