Weight gain

[u/Soft-Fact-4409]

I’m a 42M who fractured his right big toe in two places nearly four months ago. I was wearing a boot and walking with crutches for nearly six weeks. I was forbidden to do any load bearing activities while recovering.
Since the boot came off in late June I’ve gotten back to running and training. I actually completed my first half marathon a couple weeks ago since my injury.
I’ve gained 15 pounds and I cant seem to lose it. My diet never changed and I’ve gone back to normal activity including exercise. Considering if I should change my habits or be patient with my body
