Why is weight gain associated with increased anxiety?

This can sometimes be the case, in my understanding, as some people find eating to be comforting, and I would fathom a guess that when feeling anxious many people might not feel inclined to exercise and the like. However, in my current personal understanding, some people also find eating a challenge when experiencing increased anxiety.

When some people get anxious, they eat to distract themselves. For some people, eating is a coping method.

weight gain can be associated with increase anxiety because of the additional symptoms it produces like agitation, constant worry, depression can be triggered. these things can either slow you down and reduce your motivation or increase the chance of you using food to cope. It can also mess with your metabolism either slowing it down or increasing making you feel more hungry. slowing your metabolism down of course will make you body digest foods slower.

Weight gain is associated with increased anxiety because people are concerned about their body image. When a person has gained some weight, they may think they are not thin anymore, and worry about what people think about them. This is why weight gain is associated with increased anxiety.

Weight gain can be realted to increased anxiety, it can also be connected to several other factora... But also increased anxiety can be a reason for weight loss

It could be something related to coping mechanisms, like eating more foods, especially comfort ones, as a way to deal with stress. Stress also causes actual physical changes to the digestive system, particularly stomach acid levels. This can cause indigestion, overeating or undereating, and irregular eating schedules from malfunctioning signals between your digestive system and your brain. Note that this is common with depression too. Also, things that are making you anxious can also disrupt your eating schedule. Say, you're anxious about a huge project, and that project is taking up a lot of time, so you are too busy that you don't eat on time or only eat junk food snacks here and there when you can.

people do not like anything that is not in their favour. When you have increased weight they mock you as you are a vulnerable target and that causes doubt and self hate

The adrenal glands on top of the kidneys have a big part to play in having anxiety. When they are stressed a larger amount of cortisol can flood the bloodstream, making weight gain very possible.

When we are anxiety, we resort to some of our most basic instincts on how to regain our mental composure. This includes eating and refraining from physical activity, because they both provide immediate comfort from the stressful state we're in.

Weight gain probably occurs with increased anxiety since stress can make people eat more to comfort themselves.
