Reverse Diet Calculator

Reverse dieting should not be viewed as a guaranteed way to “speed up” your metabolism. Energy expenditure can change during weight loss for several reasons, and increasing calorie intake may affect some of these adaptations, but this does not mean that a specific weekly calorie increase automatically creates a permanent increase in metabolic rate.

There is no universally proven optimal calorie increase for everyone. Smaller increases, such as approximately 50–100 calories per day, can provide a practical starting point because they allow you to monitor how your body responds. The calculator therefore uses a limited, conservative initial increase rather than a large jump in calorie intake.

Increasing calorie intake can cause short-term changes in body weight without an equivalent increase in body fat. Higher carbohydrate intake, for example, can increase glycogen stores and the water stored alongside them. This is why it is more useful to look at your weight trend over multiple days or weeks rather than reacting to a single weigh-in.

Not necessarily. Reverse dieting is primarily a strategy for gradually increasing calorie intake, often after a period of dieting, while a calorie surplus specifically means consuming more energy than you expend. During a reverse diet, you do not automatically need to enter a surplus, and the goal may simply be to gradually approach your estimated maintenance intake.

There is no fixed duration or mandatory endpoint for a reverse diet. You can gradually increase calories until you reach a sustainable intake where your body weight and other goals are developing in a way that works for you. Once you are close to your estimated maintenance level, there is no need to automatically keep increasing calories.
