@alexthiemefitness: Not to mention, it takes a significant amount of calories above maintenance to gain one pound of body fat. It’s more than 3,500 and depends on the person (due to metabolic adaptation among other things). And if the scale is up after vacation, that’s more attributable to your change in bathroom habits than a massive increase in body fat. Relax and enjoy yourself. You have plenty of time to change your body - vacation isn’t the time or place.
