The dangers of counting calories

Counting calories can be harmful to your mental health. It may cause you to perceive certain meals or days as failures because you ate high energy foods. Which weren’t in fact failures at all but part of a healthy eating plan.
Eating on a calorie restriction causes you to stop eating when you have reached you energy limit from that meal. This may not be the same limit your body needs to feel full, perpetuate fears of food and trigger binge eating. You lose the ability to eat naturally and the ability to decipher feelings of hunger and fullness.
If you try to adjust your intake based on the reading from the scales this is also wrong. Your body will fluctuate on both a daily and weekly basis. You are using a false feedback mechanism.
