My grandmother was diabetic. One of my sisters is. Three of my cousins are (one of whom died rather young from a heart attack). My genetic test says I am at risk. So I have plenty of excuses there, if I were ever to need to resort to that.
However, I am a fully grown adult, parents long gone, and there is no one who I allow to be in a position to tell me what to do as far as my dietary choices.
My wife is proud of me and fully supportive. One of my doctors is fine with it, other than wanting me to keep taking my statins to keep cholesterol in line (which I am doing for now, will re-evaluate every 6 months). One of my other doctors keeps asking what I am doing because he wants to lose weight too.
The diabetic sister is not only OK with my choices, but is now following my lead and starting to reverse her diabetes. And HER doctor is now asking her questions about what she has been doing, because her success over a very short term is unprecedented, and because the doctor’s husband is overweight and needs to lose weight.
So how’s that for a ripple effect? Lost over 90 pounds myself (and still losing), my sister is on the path to reversing a disease she has been fighting for years, and TWO doctors, one of whom I have never met, are learning new things that may improve their health or their family members’ health.
I don’t have to justify anything to anyone. And neither do any of you.
Edit: To make this applicable to the topic, my rule here is: Do it for you and your own health. There is no need for excuses or explanations.
If you are successful, there may be those who are in the dark and looking for hope, who see you as a shining beacon. These, you can help, by showing them the start of a path. But they will have to walk their own path, which will be different from yours. You can’t walk it for them, nor carry them. But sometimes all they need is for someone to help them find the starting line.
Others just view your shining light as some bright flashy thing in their eyes that makes them blink, so no need to annoy them with it.
