No, it's not possible.
Approx 3500 calories = 1lb.
10lbs = approx 35,000 calories.
35,000 divided by 14 (two weeks) equals an average daily burn of 2,500 calories.
So you'd have to burn 2,500 calories every day - which for most women means exercising and not eating a thing. Which is stupid and dangerous.
10lbs is not a big deal. Learn to be happy. NO ONE looks perfect.
