Understanding Relationship Between Carbohydrates and Weight Loss.
For successful weight loss it is important to understand how your body uses carbohydrates for fuel. The body has three main sources of energy: carbohydrates, fats, and protein. The preferred source for synthesizing energy / adenosine triphosphate (ATP) is glucose derived from first carbohydrates, then fat, and lastly protein.
Carbohydrates are ultimately digested into monosaccharides. Examples of monosaccharides are glucose, fructose and galactose. These sugars can then be directly absorbed through the small intestine's walls, there by increasing blood glucose levels and nourishing your body's cells. Once the cells have had their fill of glucose, the liver stores the excess sugars as glycogen, ready for breakdown in between meals should blood glucose levels fall below a certain threshold. If there is excess glucose beyond what the liver can hold, it can be turned into fat for long-term storage so none is wasted.
A high consumption of dietary carbohydrates is conducive to gaining weight and maintaining fat. Certain carbohydrates such as white bread, rice, pasta or tortillas will cause sugar levels to rise beyond normal thresholds provoking a spike in insulin levels. An increase in insulin levels further favors increased fatty acid uptake, lipid biosynthesis, and inhibition of lipolysis (fat break down).
Therefore when weight loss is your goal, restricting carbohydrates is key. Limiting your carbohydrate consumption will force your body to derive energy from your fat stores resulting in losing weight and inches.
