Totally get what you're saying! I've lost 40pnds by just counting calories and no exercise. I recently started walking because I want to build up strength and endurance. I have little ones and need all the energy I can get. Plus there are some activities I'd like to do with them this summer that will require strength, etc. However, I get the whole not needing to exercise to lose weight thing. Sounds like you're doing what works for you and have been successful! Wonderful!
Jen, I totally agree. My mom is overweight and hardly walks anyway. Just doesn't want to, which is fine, but she's older...so when she does become ill or if she were to hurt herself she'd have a harder time in recovery because she wasn't fairly strong to begin with. This was another motivator for me to start walking!

. There are VERY valid reasons to move your body.
