It seems to for me.   
I've noticed, over the years, the more anxious I get the more I eat and the more weight I put on.   
I've been fluctuating between 104kg and 114kg for years now.  
I'm starting to get fit again, I do regular cardio, I'm getting back into running (another anxiety trigger for me) and I'm changing my diet to lose weight.    
I've noticed I hit walls, 114kg seems to be a relative stable weight for me, if I try lose weight my anxiety increases, but when I get to 110kg (every time) my anxiety ramps up, and I often cave and end up gaining a couple of kg again.     
I'm pushing through it now, but it's hard.   
I'm hoping it'll get easier with time, but I know if (when) I get to  104kg the same thing will happen again, and again at 100kg.      
Anyone else experience anything like that?   
Anyone know what might cause that?
