I’ve started with IF. A girl I work with made a comment after I mentioned I was doing this and having just OMAD. I normally don’t say anything to anyone for this very reason, but it happened to come out. She said “you should have at least 5 meals a day!” I started to explain why that wasn’t what my body needed, but she was stuck with her thoughts. Sigh…
What do you say if you have a skeptic in your life?
You just say, “It helps me heal my metabolism” or “I have a medical condition and this treats it”.
I usually say “If that is what works for you, that is wonderful. Unfortunately, it does not work that way for me. I do what I need to do.”
you don’t have to convince anyone that what you’re doing is right for you or that what you’re doing is right for them 
“i’m so glad we’ve both found what works for us even if it’s different”
I like to tell those people that I am an advanced life form, a highly evolved warrior-beast of mysterious ways, unknown to their simple tribe.
LOVE all these!! Thank you!! LOL
Yes, I feel great so all the nay sayers can zip it!
People only know what they have been taught or heard. No one thinks about people with insulin resistance or even what it is. Most people think if you fat it’s because your lazy and they fix in their mind is calories in calories out and if you fail on that it’s because your lazy.
We all know that couldn’t be further from the truth! We know weight gain is a hormonal issue and we know how to fix it.
No one at my work preaches because they have all seen my progress and there is no denying where I have come from. If I was in your position I would just say I have found what works for me and that’s the most important thing.
I have learned to not tell people or go back an fourth with people about nutrition.
I no longer feel the need to explain to anyone what I am doing. They’re not really interested in anything but pushing their own agendas. If someone was really interested, they would ask and I would love to explain. Coworkers have watched me lose 50+ pounds, and while they are always interested on what I’m eating, no one ever expresses any onterest in playing along.
Their loss.
I’d simply say…“that may work for someone with normal insulin response. It doesn’t and won’t work for me.”
As the saying goes (credit to Dave Ramsey, which is where I heard it), “Those convinced against their will, are of the same opinion still.”
No need to win the argument. Just let the results speak for themselves. 
A couple of options here:
I used to be nicer about these things. Then I realized they weren’t being nice, even if they thought they were, and their whole position came down to a very, very misguided notion that they knew me and my life better than I did. We have no time for such shenanigans.
NOOOO time…i don’t know why it still shocks and irks me that ppl think this AND actually speak it…out loud. 
when i’m feeling especially froggy i say:
“ok cool, could you let me know when i need to go to the bathroom? i’m sure you’ll know before and better than i ever will”
Oh, I have to remember that one…definitely worth repeating in the face of unsolicited advice.
