- They had less fat
- They had more empty calories from carbohydrates.
Think of carbohydrates as sugar because your metabolism rapidly converts starches to sugar.
As Americans ate more low fat foods and more empty calories they gradually became fatter and fatter. The result is the obesity epidemic that is now the number one public health problem. The reason for the weight gain is easy to explain. It has to do with blood chemistry. Remember carbohydrates are sugar. A bagel is no different than a candy bar. It is basically a carbohydrate that becomes sugar after it is digested. Sugar stimulates the body to produce insulin. Insulin in turn drives the fat cells into storage overdrive. This causes weight gain.
As people continue to overdose on low fat high carbohydrate foods their cells become more resistant to insulin. This causes them to gain even more weight and also increases their insulin resistance. The result in many instances is Type 2 diabetes.
The lessons to be learned is that fat in your diet is not necessarily bad. Refined carbohydrates in your diet are always bad. Eating a reasonable diet with a balance between protein, fats and whole grains is always good.
You are what you eat. A good rule to follow before taking a bite is to ask yourself whether this particular food will nourish me or it it just empty calories. To learn more about healthy eating refer to our book TriEnergetics.
