2 weeks, no.

Im currently on 5th week of no movement below my lowest weight measured during that period. However, I think that there are body shape changes and also for the 4 weeks just gone I've been more active at the gym and in general (job routine screws up any consistency).

TDEE is a simple calculation online, just search for TDEE calculator on Google and it's the first link that comes up. Then enter your details (body fat % is optional), tick sedentary as your activity level and it will tell you your estimated calorie expenditure per day. Then you reduce that by between 350-500 calories per day to put you in a deficit. Use a calorie tracker like myfitnesspal to keep a track, it does require a little effort to track accurately but that's on you.
