Hang in there!
I believe we've established through these forums the SLD does not have the instant, almost unbelievable results for those of us who are close to our ideal set point, with only a little weight to lose (or none), who are faithful exercisers, who already have a healthy diet, etc. The effect of appetite suppression is slower to kick in, and it is not as overwhelming. It would seem the fewer issues that one needs to correct, the less effective SLD is, which really does make sense.
I am at or near my ideal set point, but my appetite (and, hence, snacking) was out of control. In the first two weeks, I had no change in appetite and gained a few pounds from the extra calories (strictly oil for me). But after the two weeks, the appetite suppression did kick in. It's nothing earth-shattering, but it's enough to curb my incessant snacking. The extra pounds also came off. I have not had any additional weight loss, but I feel better about not constantly snacking and thinking about food.
It wouldn't be reasonable for me to lose any more than a few pounds, so that is not my focus. My focus has been the nonstop eating, and my goal was to make that more reasonable. I am now in week 4 and plan to continue on. So stick with it, everyone, even if you don't see immediate results. For those of us who are already close to where we'd like to be, it will take longer to see any results.
