I'm a 267 lb guy who needs about 3200 calories to stay my current weight. Well, I've been cutting back on my eating, and eating more healthfully so now my calorie intake is roughly around 2000 a day, walking 30-45 minutes daily PLUS 30 minutes of Hatha Yoga at night. Though it has only been 2 weeks, there hasn't been one pound dropped from my body. Yes my shirts fit better, and I'm more comfortable in a 1X than a 2X now, but I was really hoping for a weight change by now. Could I have shocked my body too much? It was all based on a one day decision and then the next day things were different. I did the same thing when I quit smoking, I just decided I was done and quit. It's now been about 6 months for the smoking and I have 0 craving. It's been two weeks for the lifestyle change, and no change in my weight at all. Am I expecting too much?
