They explained that during the week, their diets are strict, regimented, and controlled. Once the weekend rolls around, it's all out the window: indulgent brunches, Bloody Mary happy hours, and a Saturday spent bar hopping are all the norm. They told me that they "bank" calories during the week to use on the weekend. While I definitely give myself a little break on weekends, I am still pretty mindful of what I eat. Especially since two days filled with booze, fried foods, and refined carbs is enough to leave me feeling hungover into the work week.
