The scale says I gained weight during my trip; if I know my body (and I do), I will lose 2-3 pounds of it in the coming days. I believe this extra weight are mostly water retained in my body due to different types of foods I consumed and the long flights I took. so even though I have eaten during the trip more than I usually do here at home, I am not too worried; the weight I have gained will be lost soon.
