Gotta remember muscles are heavier than fat, you will fluctuate for a while before you settle on the new weight.
Now, there is this special diet I heard of. The main point is you divide days in odd and even. On even days you will have sex in the morning and keks in the evening. On odd days you will have keks in the morning and sex in the evening. You keep it up for 4 weeks and if there is no weight change, you gotta skip that keks.
Note for Americans: Keks is something like a cracker or a saltine.
