new and going ok

i have been using my fitness pal for about a week now, think it is brill. i am in UK, 6'3" male and at Christmas weighed in at 21.5stone, very unhappy. since then i have been using the gym at least 4 times a week, currently weigh in at 17.4stone. lost just over 9lb this week by eating very strict and using the gym 6 times. i have cut out all carbs, or at least have very little. upped my protein intake and utilizing weights a lot, this so far works for me. anyone one else doing the same thing? training in hampshire uk area?
