I am about 5-10. In 2008 I lost 50 lbs, from 235 to 185 (still my current weight as of this morning).
I did it with almost no ST whatsoever: just cardio and diet. I did not become emaciated nor lost muscle, in fact, I became very athletic. I have a spreadsheet with the exact number of minutes and which exercise for every day of that year, as well as the "extra" foods I had each day (talk about it not being a strict diet). The exercise was mostly ice skating, ski, soccer, tennis, with some jog and swim.
Good luck, and my advice is to just spend the time and effort. Whatever you do, if you put effort into it, about an hour every day, you will do alright.
