You lost 15# in 2 weeks and have lost what 1 lb the next 2? That is NORMAL, that is not a plateau. WAY too soon to try to force things. If you are satisfied/not hungry, then hang tight.
First you shed a lot of water and a little fat. Then the body takes some time to readjust to its new stasis...often hanging on to a little water in the process as things rearrange, then you lose a little more.
Weight loss is not linear and 2 weeks does not make a plateau.
