As part of the run , some people are fasting to sharpen faster ( reduced their body fat and achieve their ideal weight ) .Is it works, and how it works? ?The use of fat stored in the body, called lipolysis is regulated by the balance between the hormones that stimulate ( catecholamines , cortisol , and glucagon ) , and one that inhibits : the insulin .To lose weight effectively, insulin concentration must be low , so that catecholamines , cortisol, glucagon and high ...But immediately after a meal , and for a few hours , the insulin concentration is high in order to reserve nutrients including glucose (sugar).Blood glucose will be stored in the muscles and liver as glycogen .Any use of food ( and especially if it is sweet) causes the release of the pancreatic hormone ( insulin) , because it is what regulates the rate of blood sugar ( glucose ) .After his release , insulin finds its basal value within 12 hours, but at 6 am , its concentration is almost back to its resting value , in any case low enough to effectively stimulate lipolysis (the lipid utilization ) .So 6 hours after the last dose of food , we can consider that we are sporting fasting , and any physical effort made at that time will draw primarily on our fat reserves.One can obviously consume before and during the workout drink with no caloric value (water, coffee or tea without sugar).Training fasting to lose weight faster , can obviously be transferred to fitness activities ( training on ergometers, or cardiovascular course ) , but it will to go smoothly, because we will accustom your body to function under this new constraint .
Glycogen (in the liver and muscles) are relatively low, people start this type of training on an empty stomach may have a hypoglycemic attack after a few minutes of effort, especially if it is intensive.
So we'll start with exercises of moderate intensity and short duration (20-30 minutes), before embarking on efforts more intensive and longer duration (45 minutes or more).
Keep on hand, dried fruit, an energy bar or a sugary drink when first hypoglycemic symptoms: sudden gust of fatigue, leg cotton, feeling cold.
If you have a hypoglycemic attack during training, sit in the back ground even to the wall, cover to keep warm, and eat some dried fruit, or your energy bar. Usually after 10 to 15 minutes, the feeling of weariness disappears, but it is better not to start training if you are a beginner.
Okay, back to the locker room, a shower, and you'll do better next time!
Management training fasting is really a personal matter, because each of us will react differently.
So start slowly, listen to and respect your body.
