keto in the uk

Options
help keto in the UK.... do you count total carbs or net carbs ? I have tried doing keto for the last 6 weeks, I lost 10lb but have put on 4lb !!!! due to I think not really understanding my macros and not once did my urine sticks say that I was in ketosis.
I am restarting keto tomorrow including exercise and hopefully stress free as I walked out of my horrible job which was making me feel so horrible about myself ... so tomorrow ...new start to the new me !
also I have read that you can change mfp to include net carbs but I use the free version of mfp can anyone tell me if I can do this and if so how ?
I have set mfp to 5% carbs - 65% fat and 30% protein and 1200 calories.
at the moment I am 202lb and 5ft 7" and a young 52. I have put 28lbs on in the last year due to the job I had and now my goal is to get to 161lb
it would be lovely to have the support from someone who has done keto and lost the weight they needed to and are happy with the results
