Anecdotally, Garcinia seems to be the most useful so far, mostly by lowering appetite. Fat burners mostly rely on 1) increasing metabolism via caffeine 2) making that effect last longer. It seems to make things worse for me by increasing hunger, and sometimes makes me feel tired like when I have a fever and I end up lying around all day. Fevers burn lots of calories too, so I suspect it's artificially creating the same effect. It's probably most useful when combined with workouts. Also I think a lot of programmers have higher caffeine tolerance. Things that keep blood sugar low are very effective in reducing weight but part of it is done by reducing water. Side effect is your brain needs plenty of sugar for processing, so it was not suited to programming work.
