Steps to lose 2lbs a week:
1. Weigh 200 pounds.
Do you fail step 1? Your photo doesn't look like you pass step 1. As I stated, 2lbs/week if you're obese.
I suspect that you've got too aggressive a goal, that 2lbs/week is simply too fast for you. Try doubling your time and setting your loss to 1lb a week - what happens to your range?
How much do you actually have to lose? If you don't want to share, I find a good guideline for rate to lose per week is 3% of what there is to lose, down to half a pound per week minimum.
So if you've got 100lbs to lose = 3lbs/week
70 = 2.1/week
50 = 1.5/week
30 = 0.9lbs/week
20 = 0.6lbs/week
10 = 0.5lbs/week - (0.3 by maths, but set 0.5 as a minimum)
