Hi there
This is just a thought, but maybe week two was a just a bit of a 'blip'? Is there something you did in that week, that may have caused you to gain weight, rather than lose? (meals/drinks out, extra snacks, feeling constipated etc. etc!) Because 5lbs in your first week, and 1lb so far this week are good weight losses.
As Starlight says, if you're not getting any side effects, you're obviously following the fat rules correctly, but don't forget that you can still consume far too many calories without over-indulging in fat (alcohol is a prime example, as are sugary treats)
Maybe try posting your food diary on here for people to have a look at, or try tracking your fat/calorie consumption on
MyFitnessPal.com for a few days to see if there's anything going wrong.
Try not to get disheartened though, you're doing brilliantly overall - it just might be something really small that needs sorting out, and then there'll be no stopping you
