I would say rather than focusing on losing 5-ish lbs, you focus on getting in shape. A lot of what you think is excess weight is probably mostly just needing to tighten up muscles, stand up straight (you're a little slouchy in your photo!
), and define yourself a little.
Is there a gym you can join? Or can you get a few workout DVDs and use them? Just working with resistance bands isn't going to do much in the long run.
Seems to me that weight is not the issue here - the issue for you is looking out of shape and (sorry ... not trying ot be offensive here) flabby.
So fix that ... and you may find that as you get stronger and more fit, you will lose those last 5lbs (or not, but you'll still look better).
