Hi there
Only lose one pound?
ONLY lose one pound?!
You've lost 1 whole pound!
Not only have you decreased your calorie intake, but you've probably greatly increased your activity. This is a lot of change in one week. It means your body is getting adjusted, and it will lose weight at the rate
it chooses to lose, and it doesn't compare itself to your friends' weightloss and say "oh well, I better catch up!"
Even if you continued to lose 1 pound each week you'd have lost 52 pounds in a year. That's pretty much at goal for you isn't it? Not to mention that if you continue to eat healthfully, and keep up the exercise that you'd be losing fat, and not as much muscle or bone. You'd also be more likely to keep it off.
Who knows what will happen in the future weeks. I do know that if you stick with it, weight loss is inevitable. And if you stick with it some more, then maintenance is inevitable.
Focus on you. Comparing yourself to your friends will only be to your detriment.
