Sometimes you can have a treat. Next time, if you can, have only 4-5 chips and don't be concerned about the rest. It's the over-fried (read refined carbohydrates) potatoes that are likely to give you a spike - lettuce, veg, a bit of fat and the protein from the meat stuff is unlikely to send it through the roof.
Chips can be quite high in the not-so-pleasant transfat which is a good reason to avoid them - the oil they're made with is not good for you - the rest sounds fine.
If and when you limit the amount of carbohydrates you eat, you might need to eat a bit more fat than you would otherwise - body has to have some fuel, and it can actually learn to burn fat - once you don't over-stock on the carbohydrates all the time.
Good luck and happy testing. And GRATZ on the 3 weeks - that's pretty good going for a start. Don't think I was that good in the beginning - or ever really, lol.
