There are many different definitons of what being "healthy" is. This word is often used in conjunction with selling whatever the latest fad is. Everyone thinks they know what "healthy" is and most aren't shy about telling you whether what you're doing is right or not. This is the thing, healthy is not a one size fits all kind of deal. Health is different for everyone, there are no rigid guidlines that serve as the end all be all in what defines being healthy.
I have many times followed the paths that others have set forth in order to feel like I was a healthy being. Regarless of whether that meant eating a certain way, having a certain exercise routine, or living a particular lifestyle. I tried so many things in hopes of finding guidelines that felt right to me.
It took me years and years to understand that I had to define what healthy meant for me as an individual. Healthy to me is doing what allows you to feel your best. It means nourishing yourself with foods that make you feel good. For me, healthy doesn't involve spending countless hours at the gym because for me that it dangerous and will only lead to obsession. I've had to find a way to stay active without overdoing it. Let's also remember that healthy doesn't only involve your body but your mental state as well. Mental health is equally if not more important than physical health. In my definition this includes practicing lots of self care as well as filling my mind with all things positive.
Like I said, being "healthy" is something very different for each of us. It's essential to explore what things enable you to feel your absolute best, (both mentally and physically). Try not to get caught up in what everyone else is doing. We are all unique so expecting something that someone else does to feel right is a longshot. Practice patience when exploring and try new things, eventually you will find the right combination of components that work for you.
I stress again that "healthy" doesn't have to mean being at the gym seven days a week and eating only chicken and vegetables. If that works for you, great, but that is not what makes me feel good personally.
Have fun exploring health for yourself. Find peace for your body and mind. Don't be pressured by fads, find what makes YOU feel great regardless of what the rest of the world is doing :)
