so today i weighted myself after workout. it said 170.1 lbs. i couldn't believe my eyes. the last time i weighted was monday, and it was 165.5lbs. I have never gained more than 1 pound in a week before. I am 6'3 tall, so you can tell i am a pretty skinny guy. I started following a pretty structured workout routine last week. i consider myself a beginner to weight training. i got my whey protein this wednesday and i take about 2 scoops a day (so about 50 grams of protein through supplement). i had two big meals in the last three days. i had a 1lb burger which was humongous on Wed. for dinnner at a restaurant and a pretty big mexcian meal today for lunch. that's was it. and i eat 3 meals a day, excluding snacks in the late afternoon and occationally late night. usually it's much easier for me to lose weight due to my fast metabolism. i actually had to make some efforts to just maintain my weight, let alone gain it. is this frighteningly fast weight gain normal?
