Running on an empty stomach to lose weight?

Physical endurance exercise performed fasting seems more effective for burning fat than the same exercise performed after eating.

Training potentiates this effect, particularly in the woman ... ??

Energy expenditure, fasting sport and thinning

It is well known, the type and duration of physical activity has an important influence on the mobilization of energy reserves of the organism. The nutritional status of a sport (amateur or not) also affects energy expenditure.

To be physically active fasting increases the use of fat to achieve muscular work.

Significant differences between exercise fasting and exercise on a full stomach

Indeed, for the same low intensity exercise, in a normal person, the effort made fasting burns about 45% fat (by "melt" fat, a reaction called lipolysis), while after the ingestion of glucose, same effort burns half less fat ??.

This observation is also true if the effort is more intense: the use of carbohydrates is twice as important if food intake is 8 to 12 hours before the service.

Running fasting can it help lose weight?

From there to lose weight?

Presumably, as highlighted the work of a team of French researchers from the University Paul Sabatier in Toulouse.

In obese person, conditions of moderate intensity exercise mobilize 47% of fat in energy expenditure, against only 31% after eating, which, if the effort is repeated regularly and is associated with a reduced calorie diet, inevitably leads to weight loss.

Long-distance race

This effect "fat-burning" has its limits.

It is maximum for an effort of moderate intensity (jogging) after an overnight fast but fall rapidly with increasing violence of effort (fast running).

However, more effort is prolonged in time, the more the body will draw energy in fat in adipose tissue and even more if the activity is practiced fasting.

The training burns more

Accustom the body to physical effort fasting also improves the efficiency of fat oxidation, through a metabolic adaptation of the body, more favorable to the use of lipids.

The woman here has undeniable advantages over man. Indeed, at a moderate intensity exercise in obese people, lipolysis and fat oxidation is significantly better for the women.

In conclusion, benefit women and exercise of moderate intensity

In other words, women mobilize more fat than men fasting, but only for low and medium intensity exercise.
