Thanks to Paige for helping me find it...
Bree I can relate a lot to your situation. I'm just 20 but have suffered with low energy and sugar issues since I was young child so at the age of 17-18 I chose to take care of my health.
I have to say I've always been on the obsessive compulsive side and never seem to be able to find middle grounds. Either I'm surrounded by a pile of candies or I'm surrounded by a pile of broccoli.
Anyway I followed E2L for a year and can say it was the best year of my life. My peer were getting "adults" in the pejorative ways meaning that they were growing in disproportionated ways and getting bulkier, fattier and shapeless.
I on the other hand experienced a proportional growth maintaning body proportions, leaness and youthfulness. I know nowadays that unhealthy modern eating plays havoc with our hormones.
Also I got a more lighter mood, I was in awe about the world around me and started experiencing things with a new attitude: music, arts, animation, nature. In a way I started feeling again like a young child who loves life and loves to explore every little poetic detail of the world. Friends and relatives used to call me "pretty angel" because of my youthfull look, light appareance and calm, relaxed and dreaming mood. It's very hard to explain but in that period I felt surrounded by magic. Everything seemed beautiful and interesting and I would look at people and things like a 3 year old stares and acquarium full of colorful fish. I was proud of my body and liked the feeling of the wind or sun on my skin and felt confortable in my clothes.
I can't remember how but slowly I moved away from that. One reason is that I started looking skinny and my mother convinced me I was undernourishing my body. The truth I realize now is that I needed just to improve my muscular tone through exercise. I was 8% body fat but lacked muscular tone. Just a bit of muscular tone and I would have looked lean rather than skinny.
Anyway I started eating out often, I started eating everything in sight, I ate less and less veggies, I started eating junk food when it was around and I added hamburgers, sausages and steaks back to my diet.
What happened is that I started to wean from that blissful awe inspiring world and started to see reality as ugly and cold (just another proof that things ARE NOT, it's how we see them)
I started developing the typical western teen disproportionate development which grew my trunk more than my legs, keeping my upper arm short and my feet long; and slowly I started looking older.
My skin became dry and dull and I developed dermatisis around my nose.
I became fatter and had a fatty belly for the fist time. I reached 18% body fat which is "average" but on me looked extremely fat and shapeless; maybe because I was 8% body fat and fat was gained in a peculiar pattern.
But what is worst I became a lot more introspective and non-spontaneous and aggressive.
I lost the ability to laugh with an open heart or wake up with a smile and instead became easily irritable and even violent. Things like cursing because I can't find something, ripping a textbook because I don't understand an exercise, punching the keyboard because the computer doesn't work.
I even started slowly to develop the idea that life is inherently ugly and people are inherently evil.
Clearly my relationship with nature and its elements faded too and I spent more time indoor and around the city and less outdoor near a string and below a tree.
I was depressed because I felt like a person had died. That person was the 17 year old. Everyone else though I was now an average 20 guy who has grown a fuller body and a less child-like (read: positive and awe-like) attitude to life. I started to believe them. My body felt like a burden rather than the companion of my spirit and my movements started to become awkward and clumsy.
But one day I was looking at my pics from that period and was thinking "how come only 2 years ago I was always smiling, I had a perfect skin, I looked in peace with myself, flexible and coordinated and creative in love with life?" Then I remember my veggie-based diet, my vegetarianism my "PURIFIED STATE" and understood I needed to go back at that. I had completely removed that experience but a bulb turned on in my mind.
I'm slowly in the middle of such process and I can assure you that the person I used to be is coming back. I can see my body becoming lighter and more coordinate, I can see my skin becoming baby-soft and clear, I can see the traits of my face softening up and the sparkle in my eyes coming back. My dreams are becoming more colorful, my aggressivity is fading, my spontaneity is recovering. I still feel the old pleasure for natural elements: the wind of my face, the water on my hands and the need to go out and walk through wood and swim in clean lakes is blossoming again. So is my creativity and curiosity. Slowly I can feel that old sense of child-like awe and peace coming back and again I started to feel surrounded by a magical peaceful environment.
Now I feel like I'm going through rebirth after 2 years in which I wasn't there but someone else was living my life.
How do I plan to never repeat this mistake and miss precious years of my life?
Well exactly what you said! No rigid structure. Lately I'm perfectly content with buying three cans of beans a day and spead them through my meals with lot of veggies, a big salad with nuts and breakfast of nuts and fruits. If I will feel the need to add variety I will look for interesting recipes. If I will feel the need for meat I will add few pieces of chicken breast to my soups. If I will feel the need to eat junk I will allow myself a slice of pizza. If I will get to skinny I will eat more avocado and exercise more.
The point is I will never "throw the baby out with the bath water"
I definitely learned a lesson about that.
With love
David
P.s. I would love it if you could make a blog-post out of my comment because I'd like to read other people opinions about this important topics as I'm sure many have made my same mistake.
