People's reactions to my weightloss

I've been using keto, intermittent fasting, and exercise to increase my health and fitness levels for about 5 months now.  Over that 5 months I've lost 30 pounds, the first 20 pounds being in the first 2 months and progressively slowing down from there.  I feel great.  I'm happier and more energetic than I've been in years. 

Now I've been getting a variety of reactions from people at my church.  My best friend who's thin herself (in a healthy way), tells me I look healthier every time she sees me.  Other people have told me that I look great or that I look like a teenager.  These are the more positive reactions I've gotten.  I've been gracious in accepting these compliments.

On the other side of things, there's the people who are worried about me.  This week someone asked me if I had a goal I was working toward to fit into my clothes from when I was a teenager and suggested they probably aren't in style any more.  I said I haven't kept them.  There was also in her comment the suggestion that I should stop losing weight.  The truth is my goal being health, I'm open to being whatever weight that means for me.  Weight loss is only a side focus at this point.  Some other people have asked my friend if I'm okay.  And people have had varying levels of concern in their voice when noticing to me that I've lost weight.  I know this is really a reflection of their mentality surounding weightloss and health.

Here's the thing I don't understand.  Why are they more concerned about me losing weight than they are about the obese woman coming each week with growing knee problems?  I'm almost to the bmi and waist measurements that are healthy for a woman my height.  I was just barely into the obese category on the charts before I started and I didn't feel good physically or emotionally.  Now I'm confident, happy and energetic, but people are more worried about me now, than they were when I was obese, sluggish, and depressed.  Why is that?  Really it feels backwards to me.  I love them, but wish they'd worry about the people who really should be worried about instead.  The ones who aren't progressing on their journey.

To the ones who've given up on their health journey, or their emotional well-being journey, or their spiritual journey, find your why.  Once you find the why that is powerful enough to move you to action, you can stick to it through years of failed attempts till you find what works for you, and finally see the results you were looking for.  My why is that I want to out live my parents, and I want to be the example of health that my kids will need if they're going to out live me.  I want to be strong enough to be in the presence of God.  I believe It takes a certain level of fitness for a body to withstand such an experience.  I want to live a life that will one day be a story worth telling.  I want to inspire others to better themselves in whatever way they need to, to become and do what God intended for their life.  I want to be physically capable of doing whatever work God needs me to do to build up His kingdom on Earth.  I wasn't building anything when I crashed for an involuntary nap every afternoon. 

What's your "Why"?  Now do the research to figure out the "How."  Experiment with yourself till you find what works and makes you feel good in your life.  Then, when God says, "hey could you ....?"  It won't matter what it is, because you'll be ready to go.
