[BradIA]

I started at 210lbs 5 weeks ago , the first 4 weeks I've lost a total of 8lb , (which is apparently the healthy rate it should be going at) , but this last week I'm maintaining 14st , 5.8lb , im eating around 1.6k calories aday around that area maybe 2k some days just really depends , I've cut everything out (sugar , quick meals) , my weight has just been exactly 14st 5.8lb all week , i train everyday some days i rest if my body is aching but that's rarely ever happening. (I take in around 80g protien aday and 45g carbs , not sure If i have to cut them out?
