You need to eat more calories. Quite simply, with that type of a workout and those few calories, your body is holding onto the weight because it thinks you are starving!
Also, if you're not journaling your food, you may want to consider doing so in your journal and tracking your calories in your weight tracker. You may also find it beneficial to record your exercise activities in your exercise tracker.
Have you calculated the base calories you need to maintain your weight? I'd be happy to help and would need height, weight, age, sex, and normal activity level. From there, it takes a calorie deficit of 3,500 calories to lose 1 lb.
Do you have any other medical conditions that may be contributing to this? Have you check with a physician?
Hope to have you provide a little more information and certainly wish you well. Nice to have you here in the WL&D forum and hope you'll consider participating here regularly.
Very best wishes ..
