Pros and cons of fasting training

Many popular brokers are convinced that running in the morning on an empty stomach is the best strategy for lose fat. Fasting training made it fashionable Bill phillips who defended that 20 minutes of aerobic exercise first thing in the morning without having eaten breakfast is more effective to consume fat than one hour of aerobic exercise after eating.

With this kind of training which we pursue is that carbohydrates stored in the liver are in a very low level, therefore the body has to turn to fats as a source of energy.

Remember that the reserves of carbohydrates in the body are limited, their duration ranges from 2 and 3 hours, while the fat ones are unlimited. 

A person of about 70 kilos would run a half marathon with the calories provided by carbohydrates while he could run 40k with those provided by fat.

Some researchers have observed that high-fat, low-carbohydrate diets stimulate muscle capacity of using fat as fuel, but this "adaptation to fat" does not translate into an increase in athletic performance since muscle decreases its ability to use muscle glycogen and therefore decreases their ability to work at high intensities and anticipates the onset of fatigue (Bruke et al., 2000, Journal of Applied Physiology)

Some of the drawbacks of training on an empty stomach are:

There is possibility of hypoglycemia

Inability to perform Workout very intense or too fast.

There is a increased risk of dehydration

We can coming home feeling very hungry and eating unhealthy things and in disproportionate amounts.

We think it's best to eat a low-fat, low-calorie breakfast before heading out to work out. We recommend a glass of juice and a toast for example. Half an hour before. They are some 150 Kcal, but we make sure that the central nervous system does not "starve" and we avoid drops in blood glucose. Avoid fatty and protein products, as their digestion is much slower.
