I don't really buy the placebo effect idea; not for the steady loss of 33 lbs. I can only really put the loss of weight to the different permutation of my food. Apparently almost no rese ...[text shortened]... as been done into it (according to Penguin's post) so it seems to be a bit of an unknown area.
The thing is, you cannot come to the assumption that X causes Y because you yourself have experienced Y after doing X, even if Y appears to be a long-term effect and you have seen the effect multiple times. The only way we have found to remove the huge number of different ways our bodies and minds will deceive us is through the placebo-controlled double-blind randomised trial.
Placebo Controlled - subjects are divided into groups: some get the real treatment, some get something that seems like the real treatment but is not (a placebo), some get no treatment. This allows us to see whether the (amazingly powerful) placebo effect, or some other effect such as other aspects of the treatment is in play.
Double blind - neither the researchers nor the subjects can, even sub-conciously, affect the results because neither knows which treatment is being given to which patient.
Randomised - Subjects are assigned randomly to each group. This avoids the danger that researchers conciously or sub-conciously assign people to the real treatment who are more likely to give the desired response.
Compelling though it is to take your own personal experience and draw conclusions from it, there are so many hidden effects that a large number of times your conclusions will be wrong. Have a look at this 5-minute video on the placebo effect:

The study I found does not appear to have been placebo controlled or double blind so it does have failings but I think it should still carry more weight than a single annecdote.
Note that I am definitely not saying that your diet is not causing your weight loss. Just that the evidence we have does not indicate it is any better (or worse) than a normal calorie controlled diet.
