There you have it !
The other thing I do (I am someone who struggled with weight for years) is to weigh myself WITHOUT FAIL on the 1st of each month. That way you can head off weight gains before they become really serious.
I bought myself one of those accurate, state of the art scales which record weight, fat, muscle mass, water content..it even tells you your "body age" compared to your "real age". You cannot cheat with this machine
By the way for those readers that do not comprehend that you have put on 5 stones, that is 70lbs or 32 kilos in international currency. A not, if I might say so, inconsiderable weight gain.
And as a further educational note for our international audience (I don't think even our ever vigilant moderator can take exception to this), Wikipedia does not define "Essex Boy" which i am sure you know, but does define "Essex Girl"
