Problems with calorie counting

The principles of energy balance work:

Take in more calories/energy than you expend, you gain weight.
Take in fewer calories/energy than you expend, you lose weight.

However, counting calories as a way to try to know, and control, your energy intake is fundamentally — sometimes hopelessly — flawed.

Calories count are imprecise
We don’t absorb all calories we consume
How you prepare your food changes its calorie load
Individuals absorbs calories uniquely
People aren’t great at eyeballing portion size
Try calorie control instead.
