Are there any Men with low BMI here around 16 BMI?

[mrsingle]

Since late childhood I've had very low BMI and no matter what I ate or diet I tried I never was normal weight. I am 6'2" 125 pounds which is anorexia weight but I know I don't have an eating disorder. Often I get anemia symptoms when I don't eat enough like if I'm active or unable to eat like if I'm out somewhere.
I was genetic tested and found positive carrying the gene for Marfans syndrome but doctors say I don't actually have it just carry the mutation, so this might explain the very thin body frame. However I also deal with severe stress and anxiety and that can affect weight gain, and when I do eat a lot I get stomach pains and painful constipation as if my body rejected eating super large meals in a sitting. Even eating huge meals doesn't help, and I've read the foods to gain weight and I love most of them and eat them but it hasn't helped. Even protein shakes do nothing I just poop more (TMI I know) and don't put on weight.

Its scary, and people assume i starve myself they don't believe It's something else.

Female, and I've never been above 110 lbs and I'm 5'6. My main problem is that when I'm stressed I'm not hungry and thus I forget to eat. Luckily no one has called me out in an obnoxious way.

Yeah im exactly the same.. Just make sure you eat often enough and especially when you're working out.. otherwise you'll run the risk of dehydration and siezures

@Offthelist I don't work out, I was talking about just going out.

Then wear oversized tshirts and pants.. No one will notice care or pay attention to it.

Start by drinking black coffee or alcohol be4 you eat. Your body will feel semi dehydrated and will absorb and store more sugars. Then drink a lot of water.

I've never been medically underweight but I do look pretty skinny at 115lbs although I'm only 5'4 so.. I just do lots of cardio.

What? BMI of 16?

That's too low, that's in the underweight range.
