Weight Loss Guides

Body weight is an overall indicator of nutritional status of a person, but more important is knowing what percentage of that weight is fat, as this component in excess can harm health.

For a long time we thought the best way to burn fat was to perform aerobic exercises, however, a new mechanism involved in strength training also shows that lifting weights helps you lose body fat.

In the journal Cell Metabolism has published a study in Boston who said that when the muscle hypertrophy will reduce body mass and normalize many metabolic values that promote health.

The mechanism by which weight lifting helps you burn fat involves the type II muscle fibers, which contract, then the rate rapidly and are capable of lifting heavy loads for a limited time.

If these fibers are developed and muscle hypertrophy with strength training, you need to overexpress the gene encoding the protein Akt1.

This protein also contribute to the process of bodybuilding, involved in metabolic processes that reduce body fat by decreasing the size of fat cells and promote the metabolism of glucose and insulin. (more…)

In the previous issue of Food Today itself the attention that maintain their ideal body weight promotes good health, currently the proportion of population overweight or obese is significant that a hundred million years of heredity have fostered during famine, those who accumulate fat in times of plenty, that losing weight is, therefore, very difficult for most people and that fad diets and miracle cures are not losing weight. So what should be done to reduce your weight?

The only way to lose weight is to ensure that regular intake of food provided substantially less energy (in kilo calories or kilojoules) than the cost of heating the body to carry out normal activities and exercise to practice .

When you reduce food intake, metabolism decreases by about 15%. The margin between the energy expenditure and that provided by the diet must be at least 25%, and preferably by 40%.
If a woman who normally consumes 2000 k cal diet that follows provides 1,500, the margin between its reduced use (2000-15%) and its contribution is only 200 k cal per day.

This means that employs more than 5 weeks to lose 1 kg, a weight reduction unacceptable.

Consequently, if the energy gap is inadequate, weight reduction is so slow that the motivation is lost.
The normal power consumption of most women, unless they do regular exercise very intense, is about 2,000 k cal per day.
