Why won't my scale budge?

Sorry this is so long!  But I am desperate - more info is better right.

I am new here and hoping someone can enlighten me!  A little background on me, I am a 5'5'' female.  At my highest weight I was 173 in college and my lowest 120 after a very stressful time.   Since my low, the weight has been creeping back.  In that time I moved in with my BF, discovered I have hypothyrodism, quit a nicotine habit and had a birth control implant (Implanon).  Right now I am about 135 (I don't really want to get on the scale). 

My weight always comes and goes in 5 lb increments.  So when I got to 130 I upped my excercise.  I went from walking for about 20 minutes per day and horseback riding to jogging and using the Firm 20 minute ball workout and walking.  I was excersing before work, at lunch and often times after work.  Before moving in with BF I ate very little - normally 1200 calories or fewer.  At his complaining I gradually started eating more and worse food.  I know that was why I was gaining.  I also know that I was probably eating way too little back then.  I lost a few pounds last summer but over the holidays I have gained it an more back.  I have been trying since January to lose 10 lbs and nothing is working. 

I did Jillian Michials 30 shred for a month about every other day.  I started jogging 30 minutes alternating with the firm video.  I have also been horseback riding and walking for 45-60 minutes 4-5 days per week.  I know that I am more toned from the weights.  However, my pants are  getting smaller not bigger so it's not the increased weight is not just from muscle.

I struggle with what to eat.   Almost every day is Breakfast - 1 egg + 2 whites and 16 oz non fat sugar fee latte; snack - apple; lunch - salad (lettuce, tomato, mushroom & sometimes canadian bacon with 1 tbls 2% cheese & Low fat vinegarette); snack - whole grain bread & 3-5 slices canadian bacon; snack - fruit; dinner - salad with grilled meat; desert baked apple with a lot of fat free coolwhip.

Most of my calories are in the evening.  If I ate more throughout the day would that help?  I get bloated, etc. if I eat a lot at lunch.  That's why it is pretty skimpy. 

Please help, I have had weight issues my entire life.  I lost all that weight and I am scarred to death I am going to gain it all back even though I am trying like to not.

Hi!  I hope I can help!

Let's start at the beginning...  you should provide more information. The number of calories is important, but how is it distributed? proteins? carbs? fats? have you written a log with those information? without that it's hard to help.

From what I see you are sorely lacking proteins in you diet. They will help up maintain you metabolism, wave off hunger, maintain lean body mass (LBM). etc.. don't forget to included good sources of fats (omega-3 , fish, walnuts etc...)

Also, what do you want to do exactly? maintain or lose? I'm sure me and many other members (not all from what I see) can help you with food choices, but the motivation needs to be in you to start with  ;)

dedicatedforlife, 

thank you for your response.  After your comments last week I used this website to log my calories and activities.  I had been writing things down but not analyzing anything but calories.

My goal is to lose weight - 10 lbs, tone up and then maintain for life.  Here is what last week looked like.  I should also disclose that on the days I was in the 1600 calorie range at least 300 calories were from dessert.  How important is the source of calories?  I normally try to only indulge a couple times per week.  But on one of those days I would have only eaten 1000 calories if it wasn't for the dessert.  If I totally eliminate, I have a tendency to binge.  Per your advice, I also tried to add protein to my lunch meal.   

My workouts included 4 mph walking, Jillian Micheals 30 day shred video, horseback ridding and jogging 5 mph.  The weekly average was 36 minutes.  Should I increase this?  Per this site total calories burned was 1712 from the exercise alone.  Since I have a desk job, I used Sedentary on the burn meter.  It calculated I burn 1700 per day.

Hopefully that is enough information for someone to make some suggestions.  I am tired of unsuccessfully trying to figure this out on my own.  Any advice is much appreciated!
