I'm seriously considering inventing some lie about my blood sugar, dictating a strict diet if I am training.
Because all the crap I've had to hear from family, strangers and to a lesser degree, friends, gets tiresome very quickly.
Prime example: I was visiting my dad's, and my brother was there. This was when I had just begun training. I was preparing some supper, cooking lots of pasta and preparing some minced beef. Also drinking half a gallon of milk during the day.
He kept commenting. "Why are you eating all that, it's wrong. It's a waste. Don't eat so much. Drink water instead.". He went on like a broken record for a few minutes, repeating the same content yet in many different ways.
Ironically, my brother has started training as well, and just recently I visited him and we stood in the kitchen where he, after a workout, was drinking milk, cooking pasta and preparing vast quantities chicken.
The irony. I of course pointed this out to him with some laughter. "see how full of bullshit you were"
Not long ago, during vacationing to Greece, I was eating tuna and carrots etc (dieting), and my sister commented on my eating habbits for the manieth time. I finally burst out how full of shit she was and how she was appearently just trying to sabotage my efforts.
