<human>: Give me a shortened version of the text

I went from 144 lbs on Nov 1 to 136lbs on Dec 1. I'm super happy with my weight loss and thought it was probably 50% due to my healthier eating and calorie counting with MFP and 50% due to my 3 to 4 runs per week.

Well, today I discovered some statistics in my running app, which showed me that I did 20 runs in November and burnt about 6.500kcal altogether. That's not even 2lbs and I lost 8! So my success is probably more like 80% due to diet and 20% due to exercise! Although this might be obvious to most people, it was such an eye opener for me. 

Why am I happy about this? I've been fighting off a cold for the past two weeks and also have a strained muscle. I thought this would make weight loss impossible and I would have to settle for maintaining for a while. Obviously not! I just had to share my excitement :)
