Obesity is already a global epidemic, according to the WHO (World Health Organization). The WHO also states that the obesity it is one of the most serious problems of public health in the TWENTY-first century.
Traditionally it was thought that obesity was the sole responsibility of the individualof your diet and the physical exercise that makes (the false dogma eats less and spends more). But today we know that this is not so. Obesity is a multifactorial disease in which the environment of the individual has a great influence.
Despite what many think, the hunger control is much more than force of will. The regulation of appetite it is a extremely complex process that we are gradually finding out some of its mechanisms.
Hormones, chemical messengers using our body to send signals to the brain, play a pivotal role in the regulation of satiety and appetite.
In particular, since we know that the leptindiscovered in 1994, and the insulin they are two of the main hormones involved in the processes of the regulation of satiety and appetite. Leptin is a driver of metabolism and a regulator of hunger, and is known as the hunger hormone.
The paleo diet or the model of nutrition evolutionary advised to avoid the consumption of dairy, legumes and grains. And with them, any derivative, such as bread or pasta made with wheat flour.
The reasons why it is not recommended consume grains and its derivatives are:
- Have low-density nutritional (the nutrients that give you respect you need).
- Induce high peaks of glucose and insulin in the blood (one of the risk factors of type II diabetes).
- Contain potentially dangerous substances or antinutrients (are the defenses of the grain against external attacks).
- The gluten they contain contributes to the permeability and intestinal inflammation (especially in people with celiac disease).
This is one of the main doubts that arise when we speak of the paleo diet. Despite the fact that many people think that the paleo diet is high in proteins and fats, and low in carbohydrates, is totally fake. The paleo diet is not low in carbohydrates.
The paleo diet is a nutritional model based on the evolution that tells you the foods that you should prioritize, you need to take in moderation and that you have to avoid. But always referred to food, never has amounts or percentages. For this reason, affirm that the paleo diet is high or low in carbohydrates does not make sense.
One of the myths more widespread when talking about the paleo diet, or diet evolutionary is that the life expectancy of the human being in the paleolithic was low, close to 20 years, and it gradually grew thanks to the agricultural revolution and later development of civilization. Which leads to affirm that the human being in the paleolithic era died young. Nothing could be further from the reality.
In the first place, the life expectancy is the average number of years over which lives a population in a given period, that is to say, the average age of the deceased persons. The life expectancy it does not measure the maximum age reached by the longest-lived population, but the average age at which it dies.
