Advice?

Ok so I've been working on my weight for almost 4 months and have lost 13.5 pounds but lately even though I'm working hard my loss has slowed to .5 pounds a week. Here's a good example of my daily diet:



Breakfast: 1 scrambled egg

Snack: fruit & 1 or 2 peanut butter crackers

Lunch: oatmeal

Snack: kind bar from whole foods or fiber bar

& a cup of organic veggie juice

Dinner: grilled chicken bread & carrots



I also do 30 minutes of the fitness blender HIT workouts everyday during the week.



I get a little to snacks on the weekends but I try to be very active and I was losing a pound to a 1.5 a week and now it's soooo slow. In losing motivation and getting frustrated.



I'm 31 years old with a very slow metabolism. Everything I eat packs right on. I went from 152.5 to 139 but it took forever! I want to lose about 5 more pounds and then wook on toning up my mommy belly from there.



Thoughts? Anything would be appericated
