For me making peace with food is all about understanding YOU!! What nourishes you, what you need emotionally what you need physically and what you need for nourishment (food). So often we use food to cover how we feel or provide the love and happiness we lack in our lives, I am all to aware of this behaviour and I've used food from a very young age to suppress my feelings or provide me with the happiness and love I was lacking.
I used food for the majority of my life like a drug, I used it to make me feel better, forget about my life even if it was just for a little while and to hide myself and my feelings, teaming that up with yo yo dieting starting at a very young age I went from comfort eating to restriction and deprivation then to binge eating because of the harsh restrictions I was putting on myself and pressed repeat for many of years
Making peace with food requires you to dig deep and really look at your own lacks and emotions in life which can really be confronting and hard at times, but for emotional or stress eaters it's essential for either weight loss or health in general, with that understanding we realise that food isn't the enemy, it's there to nourish us and provide us with energy and fuel and health that's it it's not there to make our pains go away or comfort us (although sometimes a good slice of cake can help hehehe) it shouldn't be our go to fix me resource.
Understanding YOU, also means understanding what foods also work for you, our habits and conditioning around eating can also play a big part on making peace with food, having Italian heritage I would eat pasta most nights a conditioning learnt at child hood, it was cheap, fast and something we just ate without thinking about it. I would wake up sick in my tummy from it but I never really looked into it until I wanted to get serious about my health, these days I barely eat it and I barely get tummy upsets. Just another way of doing what's right for and your body even if it's something that familiar and safe, it's ok to let go of things that don't serve or nourish you, be it certain foods you've consumed for years, certain beliefs you have around food or if like me you use foods to comfort or make you feel better fro many years!
Make your own peace with food, Food at the end of the day is just food, eat to nourish not to punish xx
