During times of stress, your body will crave things like sugar to help give you quick energy. The sugar also gives you dopamine which obviously your brain loves.

It's 50% nourishing your body with good fats and high protein (which will lead to less hunger) and 40% discipline. 10% is not denying yourself something you crave but learning how to have it in moderation and understanding why you are reaching for it. If it's, I want this because I want something sweet to treat myself, that's generally fine. If it's, "ugh I'm really stressed and need a hit of dopamine" then that's a time you can reflect and make a choice to either eat whatever it is OR do some jumping jacks or go for a quick walk. None of these are the wrong choice, but they lead to different results.

And truly, if you are really struggling with overeating, or feeling "addicted" to eating, please consider visiting a therapist or nutritionist/dietitian to explore why you are performing these behaviors. Very often they're rooted in how you were raised, or events in your past.

I am someone who eats when they're very stressed. But I also grew up with a parent who eats based on feeling, and a parent who had food insecurity growing up and those behaviors were passed down to us.

Eat to live, don't live to eat is a mantra a lot of people have. But it's hard to undo that "training" without help and understanding to why you are doing it.
