Counting Calories is a Ridiculous Way to Try to Lose Weight

It just Does NOT Work. We’ve all done it.

The calorie theory of obesity has been perhaps one of the greatest failures in the history of medicine. Given the number of excess deaths caused by metabolic syndrome, you could argue that it is a bigger disaster than World War II. It is based on a complete misinterpretation of the energy balance equation.

Body fat gained = Calories In — Calories Out

This equation, known as the energy balance equation is always true. So, looking at this equation, people then say something like ‘It’s all about restricting the calories you eat’, or ‘All diets work by restricting calories’. On the Calories Out side, you hear things like ‘You should exercise more’. This is the standard Eat Less, Move More approach. Doctors, even so-called ‘obesity experts’ and various health professionals say stuff like this all the time, but they’re completely wrong. The problem is that they don’t even know why they’re so wrong.
