Not everyone is supposed to be thin

Human biodiversity is a thing. We're supposed to look different from each other.

We have different skin color and texture, different hair, different eyes. Our feet are different sizes. Our fingers are different shapes. The length of my earlobes is not the same as the length of your earlobes. The placement of moles on my body is different from where they are on your body (if you have moles at all). Our proportions are different. 

And our size is different. 

Bodies are meant to be diverse.

Fat bodies have always existed.

Thin is not the ultimate body shape, though popular culture would disagree.

Many people can diet and take other extreme measures and become temporarily thin (or thinner). But this does not make it automatically healthful. Thinness is not a part of everyone's DNA.

If your body does not want to be thin (even if your brain does), it will create an internal war to try to get there. If you want to be at war, be at war.

If you want to be at peace, welcome the size your body wants to be. (You don't have to welcome it with a smile. Feel free to rage and cry if that's what's there. Those feelings will still be very different than the feelings of being at war).
