Hey Jason!
Congrats on your success! (guys are so lucky when it comes to losing weight, darn it!)
I also added almonds in several months ago, but other than that, stuck with induction. As far as the rungs go, it would seem to me that you'd be pretty safe incorporating about the first half of the list.....and then it could get tricky on the second half, especially the starchy veggies, the additional fruits (beyond the berries and melon) and the whole grains. I would definitely go slow when it comes to the second half of the ladder. The extra veggies, the nuts/seeds and the berries...would probably be fairly easy.....but as far as the others go, I would definitely only do one at a time and take some time to evaluate how each one affects your weight....before thinking about adding in a new one.
When I maintained for about 12 years in the past...I basically added in more veggies (didn't even worry about how much low-carb veggies I ate), the nuts and low-carb fruits. For the other items....I only ate them on rare occasions (higher carb fruits, starchy veggies and whole grains)......and never incorporated them in on a regular basis. BUT, I'm 1) not a guy and 2) VERY sensitive to carbs....so I had to be really careful. I also had to be careful about the amount of cheese and other dairy, even on maintenance. I think being a big guy, though.....you will be able to incorporate these other things rather easily. You may have to be a bit careful while losing the remaining 13, but on maintenance, you should not have difficulty going up the rungs, as long as you don't get carried away and have any sugar-fests.

Forgot to add....for pork rinds....do you guys have convenience stores in Canada? (7-11, etc.) Those little mini-marts connected to gas stations are also pretty good when it comes to carrying pork rinds. Seems to be easier to find pork rinds around here in the convenience stores and the gas station mini-marts than it is in the grocery stores (though some of the grocery stores do carry them). Also...most sub shops and sandwich shops have them too.
