Why is it so hard to stick with changes?
We are the sum of our habits - also the unhealthy ones! Habits are behaviors wired so deeply in our brains that we perform them automatically: it's like being on autopilot. They feel safe and easy. That's why we can't simply eliminate a bad habit.
Instead, we need to replace it with one that provides a comparable reward!
Why can't we stop eating things that we know are unhealthy for us?
Most of our bad eating habits revolve around emotional triggers: stress, boredom, reward, comfort, social... Changing these habits is hard because they deal with real needs. How do we cope with pressure, anger, sadness and loneliness... besides eating?
We need to deal with these emotions in healthier ways!
