Question from a skinny friend:

if she is still underweight then clearly what she eats matches her energy output. For all you know she twists and turns constantly in her sleep and thus uses more then the average person. Eating large quantities does not make you a binge eater. Finishing your plate does not make you a compulsive eater. Most people who suffer from either are considerably overweight or have bulimia. She is probably eating less then she thinks she is or has a fast metabolism.

Also when you say she eat super healthy it doesn't actually give any indication of calories. For example if she were to only eat vegetables, it would take an awful lot of it in order to get to even 1200 calories. Alternatively if she were to munch on nuts all day, hitting 3000 would not take much of an effort.

People do have some fat unless they exercise their bottom off. So again unless she is actually overweight or at least in the top half of her BMI or has a very high bf%, there seems to be nothing wrong with her. By all means tell her to add exercise into her life, but the situation you have described is very general and unless she is compulsively eating her own weight in cheese or upwards of 5000 cals a day and not gaining any weight, in which case she should go to her doctor, because there is nothing we could tell her, she is fine.

My question would be - how old is your friend? Sounds like she might be gifted with a fairly fast metabolism. I was the same right through my 20's. However now that I am in my late 30's things are not the same, and I have to be a little more watchful of what I am eating.

So my suggestion to your friend (in hindsight from my own experience) would be to eat good quality food in the right portions, and try to get some regular exercise to maintain bone and muscle density.

Cool! I'm grateful she can be a woman free of diet stress
Don't know how likely it is can motivate her to excercise though....
Any suggestions how to make it something she would actually consider?

Many thanks again.
She eats a good variety I mean way larger portions of vegetables fruits proteins grains healthy treats dairy whatever she wants I guess. So that is the best of my ability to clarify. I guess the fruits and veg take up a lot of space. I think she has varying a wide range of different quantities amounts some days is not always consistent. I could ask her more specifically.

What could I tell her to calm the "do I stick out for eating so much in public" and should I really be finishing all this not to waste is that normal?" Worry? How can I explain to her better what overeating/binging would be quantify for her body?

Multiplicity of thanks and gratitude. She is a worrier and has enough other stuff to worry about but needs/looks for rationale to stop her questions.

I eat upwards of 4lbs in fruit and veggies all day and only hit about 1350 a day, if not less (yes, I do eat other foods as well, but the bulk of my diet in terms of volume is fruit and veggies).

One of the things to consider is that you are here probably because you are trying to manage your weight and she might read through all this and talk to you about, because she wants to 'share' your journey and make you feel good. If you talk about she might simply want to chime in and assure you that she is not perfect either.
