Weight gain after surgery

It's been three months since my hip surgery, and about two months since restrictions on activities of daily living were for the most part lifted. Only recently have I been able to start adding in more exercise activity; besides the post-op immobility, my running and exercise prior to surgery were limited due to hip pain.
So, I'm gaining weight. Of course. I expected a little weight gain, but that doesn't mean I like it! I'm a firm believer in my mom's advice: "Never gain the first pound". It's harder to lose weight than to prevent gain!
Now, I actually know exactly how much weight I gained since surgery, because they weighed me before surgery to calculate anesthesia doses, and I was weighed this week at the doctor's office. I have gained five pounds and I'm currently at the highest weight I've ever been, as far as I know (based on looks since I don't weigh myself often, as I don't own a scale). I was definitely aware of this weight creep, so I'd already decided to do my best to mitigate it before I had the weigh-in.
I noticed that almost every evening I was eating something sweet before bed, so I figured that would be the easiest thing to cut out. To make sure I stopped, I just ruled all desserts and candy off-limits for the month of August. It was bit arbitrary, but it cut out a bad dietary habit and can't hurt. I know it would be smarter to also loosely count calories, but for starters, this was an easy preventative measure. I think when I can be a tad more active and am allowed to do more activities (and for a longer time), I should be able to lose any weight I gained, but for now I'm content to maintain where I am.

I love good food, so it's not easy to make huge changes to my diet, and I don't love skipping dessert when we go out to dinner. But I'd rather make a very small sacrifice now than have to face a large weight loss later.

Now, with August over, I realize that I was pretty much just holding steady for the month - no extreme weight gain as far as I can tell, but certainly no loss. I don't think my deprivation made a huge difference (and BTW, no I was not suddenly brimming with energy or cured of acne or anything). It wasn't a bad for me to get some practice saying no, however.

Over the next few months I'll try to drop the extra weight, but I'm not stressing over it too much. Priority number one is to get healed and healthy, then I can worry about weight.
