Burn Fat While Exercising
Carbo Loading in Nutrition Training
Producing energy aerobically also promotes good health by maximizing the efficiency of the body’s nutrient transport mechanism via the bloodstream and optimizing the efficiency of the heart and lungs. Burning fat as the main fuel for all our daily activities also spares blood glucose for use by the brain, thus improving mental as well as physical performance.
Movement creates energy, and the healthiest and most sustainable form of movement is exercising at an aerobic, fat-burning pace. Slow Burn presents an entire lifestyle plan built around slowing down and achieving more. While it is true that one can lose weight faster by training faster, the excessive stress on the body makes it unsustainable in the long run. Stu Mittleman delivers a philosophy for creating energy throughout the day without getting tired and explains in detail how to train the body to get its energy from fat rather than from sugar.
While sugar-based energy is fast and effective, the problem is compounded by the fact that the human body does not have a lot of sugar to use for energy. Of the approximately 160,000 calories stored in the human body, only about 2 [link widoczny dla zalogowanych],500 come from sugar [link widoczny dla zalogowanych], with fat making up most of the rest. When the body signals the drop in sugar levels through loss of concentration, dizziness and lack of coordination, the answer of increasing sugar intake sparks a vicious cycle.
Sugar addiction is increasingly plaguing modern-day cultures. MedicineNet.com quoted figures from the U.S. Department of Agriculture (USDA) that showed Americans consume 156 pounds of added sugar each year on a per capita basis. The use of sugar as an energy fuel is also practised by exercise endurance runners, who advocate “carbo loading” before a big race such as the marathon to maximise the storage of glycogen in the muscles.
The best way to burn fat is when the majority of training is of low to moderate intensity. This leads to healthier blood circulation and calmer, less stressed out lives because most of the energy is drawn from fat, encouraging the body to rely more on slow-twitch, aerobic, fat burning muscle fibres which are better suited to face up to the challenge of long-distance quality living.
Fat is the most efficient of fuels, containing more calories per gram than carbohydrates or protein. With 80% of the calories available as fuel to the body, fat is far more abundant than sugar and provides the greatest natural source of energy available to the human body. Indeed, the emergence of stored fat was the extra fuel tank that created the possibility of long distance hunting and gathering as practised by early man.
Developing a dependency on this small and finite fuel source stresses the body and leads to the long term effects of frequent energy highs and lows [link widoczny dla zalogowanych], inconsistent energy levels, an acidic stomach, physical aches and pains and vulnerability to colds and allergies. The way to combat this problem is to transform how the body uses its energy stores, from the sugar-burning anaerobic system to the fat-burning aerobic system.
Stu Mittleman is a fitness educator and ultradistance running champion who set the world record for the 1,000 mile run in eleven days. In his book Slow Burn: Slow Down, Burn Fat and Unlock the Energy Within [HarperResource, 2000], he shares the principle of energy and endurance and why moving aerobically taps into the body’s most inexhaustible source of energy: fat.
