> The reason is a doctor told my parents not to feed me any sugar until age 2-3

What I take from this is that the actual reason is, "I had parents that were concerned enough with my nutrition to not feed me much sugar as a child, and those healthy eating habits probably didn't stop after age 2-3. I now cannot gain weight, even if I eat what I perceive as a lot of food (because I grew up eating healthy food and portion sizes)."

I was one of those "I can't gain weight/put on muscle" people for a long time. I eventually tried eating literally double what I would normally eat, and as expected, I started gaining weight.

Once I was working in London as a contractor, a colleague looked at my lunch after a while of working together, shook his head and told me "you are going to kill yourself". I hope that was indeed the worst 6mo in my life pretty much living on fast food, but I did not gain a penny in weight.

I think healthy eating habits would be the last thing that came to my friends minds when describing me.

I totally agree I'm only a sample of one that I know of, but the fact that this doctor relative of ours told my parents the cause-and-effect relationship beforehand, and it worked out, makes me believe the theory. Either way, I keep recommending it to my friends getting babies, so I'll be able to collect more data in the next 50 years. ;)

The thing is, that's the kind of gamble that costs nothing and might have immense upside, so it would be kinda silly not to apply it. My 2c.
