Proposed exercise (and diet) plan for 2/11/15

I guess that now that I have identified my setbacks all I have to do is to formulate an exercise plan or regimen that I can stick to.  I have to identify the fact that I am a beginner and that T25 would be out of my reach for now.  Right now, I have an interest in walking, yoga, and pilates.  I am not sure about yoga, but because I wish to lose weight, I am interested in working out and burning the amount of calories it takes per hour walking or doing pilates.  Here is my proposed exercise (and diet) schedule for tomorrow:
