Hi, I started Atkins 2 weeks ago ( almost) and I haven't lost one pound. I also quit smoking on the same day. And I quit caffeine.

I tried the sticks and I am not in ketosis, once a trace showed. I am now eating below 10 carbs a day and still nothing. My daily eating habits ,
decaf coffee with cream and splenda.
can of tuna with mayo for lunch and a piece of chicken or turkey
same for dinner either turkey hamburger or salmon grilled with olive oil salt and pepper.
Am I eating too much meat/fish?
an atkins breakfast bar and another decaf coffee.

Some days I don't have decaff at all or the bars. I used to eat a ceasar salad for lunch or tomatoes or zucchini but I stopped all that. ...
Did my metabolism slow down so much from quitting smoking that atkins is just keeping me even ( weight wise) ?
I have been really strict, should I take a metabolism booster? I am pretty desperate, my boyfriend started on the same day and lost 10lbs, we are both eating the same thing give or take

thank you !
