Often we eat as a way to socialize, or because other people we’re socializing are eating. Learn other ways to socialize instead:

Go for a hike, play sports, make healthy food with friends, play music or make art together, or have fruit instead of unhealthy foods. 

Some healthy ways to deal with boredom is to go for a walk. Find a comfy spot and read a novel. Find friends to play sports with or go for a hike with. Learn to garden or sew. Make tea. Write. Journal. Do yoga. Listen to music.

If you’re focusing on stress, pay close attention to it. Try to notice every time it comes up. You might want some kind of visual reminder placed where you’ll see it when you get stressed (at your desk or in the car, for example, if those are places you commonly get stressed).

Instead of eating, try some kind of exercise, such as pushups, walking, jogging, weights, or yoga. Try deep breathing or meditating for 2 minutes. Try massaging your shoulders. Drink water.

Did you put in a hard day’s work? Did you accomplish something great? Don't reward yourself with food. 

Instead, take a nap. Get a massage. Take a bath. Have tea. Allow yourself some down time.

Pay attention to your emotions as you start to think about eating (you might feel hungry, or have a craving to eat something). Notice your emotions as you eat, and after as well. 

Keep a few notes — what emotions do you feel, when, and why. What do you feel like eating? 

Do this technique for one emotional trigger for at least a couple weeks, if not a month. 

When you feel you have a handle on it, repeat the technique for another emotional trigger on your list.

If the need is a way to cope with stress, you need to find some healthy way of doing that other than eating. If you don’t, then the need will become so strong that you’ll cave and eat.
