The opposite happened to me when I did finally lose a great deal of weight, my parents started saying I was losing too much and that "I was eating like a pigeon."
Neither to my mind is true, I still have a great deal of chest fat on me and while I do eat smaller portion now, it's because that's as most as I can stomach before feeling bloated and full.
I was a fat kid myself growing up, but even my parents were overweight too.
Whenever the subject came up with my Dad and I tried to talk him into changing his eating habits, he'd quickly change the subject and start telling me that I was getting too thin, which basically meant "Go Away."
When he wasn't heaving and panting from doing the most basic things like walking or lifting a chair, it wasn't that he was severely overweight and the excess put a great deal of pressure and overload on his lungs, but that he'd always been a heavy breather growing up.
My mother wasn't much better, when I look back now at growing up I was always given such huge portions of food to eat. I ate it of course, but my brother and sister always got such smaller portions compared to me.
Now that I don't live with her anymore, my sister, who's been crocked up in her room for most of the year because of lockdown, has started eating a lot more and gotten obese as a result.
Obesity is a horrible problem that runs rampant in many families around the Western World, not genetically mind you, but that parents often pass down their incompetence to cooking and eating habits down to their children without realising it.
