A calorie is just a calorie

We all believed that a calorie was just a calorie. This would imply that obesity is caused by eating too many calories.
This is a lie. First, calories themselves are not sufficient to create obesity. Something else is needed. Second, different types of calories have different effects on the controller of obesity..
As a review, a calorie is a unit of energy that food provides. We need energy to live. The lie is that it doesn't matter which foods provide them because all calories are created equal. Therefore, if you want to lose weight, just eat fewer calories.
Instead of believing a lie, I want you to know that the key control point for weight gain is not the number of calories consumed but is based on what calories are STORED versus those burned. This signal is produced by the hormone insulin.
