Fat-burning Mechanism

Diet, insulin and body fat!

Through proper diet and lifestyle habits you can program your body burn fat all day, every day, for the rest of your life. Your body is designed through millions of years of evolution to burn large amounts of fat, and all you need to do is provide it with the proper food, exercise and stress levels.

Fat is the most efficient of fuels, containing more calories per gram than carbohydrates or protein; however, when it is not used as a fuel it is stored. Burning fat as the main fuel for all your daily activities also spares blood glucose for use by the brain - so fat-burning can improve mental performance as well as physical.

Action of insulin
This hormone is produced every time you eat and its task is to distribute glucose, produced mainly from carbohydrates, throughout the body. In most people about half of this glucose is put to use for immediate energy in the body's cells. About 10 percent is stored in the muscles and liver as glycogen for reserve energy. The remaining 40 percent is converted to fat and stored.

Types of carbohydrates, those with a higher glycemic index, cause even higher production of insulin. And some people, those who are intolerant to carbohydrates or insulin resistant, will produce more insulin in reaction to eating these higher-glycemic foods which include mostly fiberless refined carbohydrates such as most bread, rolls, cereals, sweets, and some types of pasta, but also some vegetables such as corn and potatoes, and fruits such as bananas. Eating carbohydrates in combination with protein or fat can help reduce the overall glycemic index of the meal or snack.

Higher production of insulin n fat storage
Higher production of insulin, not only results in more fat being stored, it also prompts less fat to be burned. Since blood glucose is available in overabundance when you eat too much carbohydrate, the body shifts to sugar-burning rather than fat-burning. The result is more stored fat and less fat-burning

Frequency of eating n fat burning
In addition to the type of food you eat, another factor contributing to insulin production is how often you eat. Eating more often - five or six times or more per day - can help stabilize blood sugar levels and help your body to produce less insulin. As discussed earlier, less insulin means more fat-burning. Of course eating more food than you need will also promote weight gain, so the trick is to not eat more food, but to eat the proper amount of food spread out between meals and snacks over the course of the day.

Turn on the body's fat burning mechanism - Some foods burn "hotter" than others; that is, they cause the body to expend more calories for heat, encourage activity and are not as readily stored. Proteins and complex carbohydrates are "hot" burners, such as whole grains, whole-grain products and nearly all vegetables. They are not stored as fat easily and they tell the body that it has enough fuel, so it is alright to expend energy. This heat producing effect after a meal turns on the metabolism.
