When we diet, we have to reduce calories. This happens for a variety of reasons that fall under the umbrella term called “metabolic adaption.” In an ideal world, a diet break would provide a lasting metabolic boost that would reverse some of the adaptations to dieting. This would mean we don't have to continue to cut calories to lose weight. So, if adherence had been high and weight loss slowed, you’d just take a two-week diet break then return to your previous calorie intake, and you’d continue to lose weight at your target rate. This is what was once hoped, and was my experience with some clients, but unfortunately, recent research has shown that the impact of a diet break on metabolic rate is short-lived. What this means then is: 1) If you were losing weight at your target rate before the break, return to the same calorie intake after. 2) If you were short of your weight loss target, adjust your calorie intake downward. For every 0.2 lbs short of target per week, drop 100 kcal. (~100 kcal per 0.1 kg) 3) If the reason you took the diet break was that you were going through a particularly stressful period, and this period coincided with a lower rate of weight loss (or no loss at all), then it’s best to assume that water retention was the cause of that. Just return to your previous calorie intake after the break. Of course, the art is making as few cuts as possible so that your diet is as sustainable as possible, which is where my How To Adjust Macros As You Diet guide comes in.
