One of the most effective ways to lose belly fat is by eating whole foods.
The reason for this is very simple: Natural, unrefined foods force your body to work harder to extract the fiber and nutrients, take chains of molecules and chop them into smaller versions to absorb them into your bloodstream.
This increases your body’s calorie burning because your organism must use more energy (calories) during this digestion and utilization process.
On the other hand, the processed and refined products, like white flour, have lost their complexity, and have taken on the properties of simple carbohydrate.
When foods are processed and refined, much of this work is done for you. So your body does not have to work as hard, and uses less energy (calories) during the digestion and utilization process.
Anything made from white flour, is processed in your body the same way as a simple sugar.
This means that the simple carbs in this processed/refined food are easily converted to glucose, and your body expends fewer calories processing the flour.
Whole grains, on the other hand, pack more nutrients, are higher in fiber and force the body to work harder to use them as energy.
Another advantage to eating whole foods is that many of the nutrients in these foods – such as vitamins and minerals – are co-factors in metabolic processes that your body uses to burn fat and build muscle.
The law of energy (calorie) balance: If your burn more calories during the day than you consume you will lose weight. If you consume more calories during the day than you burn you will gain weight.
Since the law of energy (calorie) balance is the number one law in fat loss, the more calories you burn during the day, the more body fat you will lose and the flatter your stomach will look.
