When i was 20 i was 230lbs of pure fat, but i held it well. A life of being ridiculed and my desire to cosplay( anime characters, video game characters) motivated me to change that. I read every single book on nutrition, picked my professor's brains, asked experts etc. Within a year i lost 90lbs. No extra skin, stretch marks healed up, but then i was a stick. So i went back at it and within a year i gained 15lbs of muscle and lost 2% body fat. I couldn't stop researching everything i could on fitness and nutrition, this led me to become (currently) a Graduate Student getting my masters in Applied Nutrition. Today, I'm 26 years old, still lifting, 155-160lbs, 10-12% total body fat, With ABS. So to answer your question, I'm struggling getting me fellow geeks to join me, plus i just want to spread the word of nutrition and exercise. Most of them remain ignorant, so I'm basically alone in my pursuits.
