Julie’s story is a testament to that.
The following are a list of reasons which may lead one to overeat. Or, another way of looking at it, large doses of food (providing a drug-like effect) may be used by people to cope with these common issues:
Chronic psychological stress
Body image disorder
Lack of control
Lack of creative output
Essentially, our mal-adaptation to modern life leads us to seek food to help cope with these psycho-social issues. We don’t need the food for simply nutrition and energy, but for stimulating reward pathways in neural circuits in our brains. Processed foods do provide a more powerful punch and can be used more effectively than whole foods.
When I work with a client who desires fat-loss, I know on paper exactly what they need to do to achieve those results. I have had many clients achieve their goals. At the same time, I have seen many clients fail. The critical factor is their psycho-social state. If they aren’t able to fulfill their psycho-social needs in non-food ways, then they will fail. They need to have a healthy state of mind if they are to develop an appropriate relationship with food.
Food doesn't cause obesity, no matter how calorie-dense or processed it is. Using food to cope with the highly prevalent psycho-social issues our culture faces is the underlying problem. Address these underlying psycho-social issues if you wish to achieve any long-term fat-loss, health, fitness goals.
