You tell everyone you know just how bad that cupcake/slice of bread/pasta bowl is for them.
You send them pictures of every single meal you make.
You make going out for meals extra difficult to organize because of your dietary restrictions.
You can't hang out with friends at night because you have to be in bed by 9 p.m. so you can get up at 5 a.m. to "beat the heat" and do your cardio.
You spam their Pinterest dashboards with your endless pins of fitness routines you want to try, motivational posters, Paleo recipes, etc.
You tell them every day how much better you feel since changing your lifestyle...
You look up the nutritional value of absolutely everything you eat — and your friends eat — on MyFitnessPal.
You offer to cook for them but substitute pretty much all the ingredients for “more natural” options.
But! FINALLY: You've started to feel comfortable in your own skin and are proud of yourself for the first time in your life.
