There are studies showing that the"zig zag" calorie intake technique helps reduce the body weight.
This method is based on the structure where you eat all the calories your body needs for one day, followed by eating 25 % of the calories for the next day.
The University of Chicago did even further research to show if the timing of the meals during the day with restricted calories matters.
The results showed that all the participants, disregarding the time of the day they eat ( breakfast, lunch or dinner), lost the same amount of weight in 10 weeks ( approximately 10 pounds, 75 % from fat, 25% from lean body tissue).
Similar structure can be applied through the holidays. Enjoy your special meals, and the next day try to restrict your calorie intake.
