hey choc, there could be any number of reasons why you didn't see any loss this week. the most likely one is simple water retention, and you may have increased your muscle mass. don't worry about it too much tho, with your diet and exercise plans you are sure to be losing fat, and that's what really counts! if you're building muscle that's a good thing b/c it'll raise you metabolism. so stay strong and stick to your plans. you're doing great!
