For me it was two things - 1) being able to increase activity level due to not being in pain, and 2) simply cutting down on how much I eat. I looked at the nutritional info for all of our favorite restaurants. I don't know about the UK, but in the US all of the restaurants have to publish that and make it available on demand. And almost all restaurants in the US give you way too much food. It's not unusual to see a dinner with over 3000 calories, which is more than what most people should consume in a day. When we go out to eat I've gotten in the habit of automatically dividing my dinner in half and taking the other half home to eat later. That in itself has made a huge difference. And I found that eating only half was usually plenty - my body didn't NEED to be consuming the whole plate. A nice side effect is my digestive system is functioning much better. I sleep better and don't end up waking up with heartburn in the middle of the night like I used to.The 30lbs weight loss is amazing too-and bound to help joints and BP. I am trying to lose a few Xmas pounds- any tips?!
The same thing happened to me (opposite knees, though). I expected to need to have leftie down last fall, but so far, so good! Also, I recently noted that -- at 18 months post-op -- my knee is still improving, so you are likely to continue to make gains for at leas the rest of the year, if not longer. Congrats!since getting the LTKR the right knee hasn't been bothering me.
