Nutritionist Isabel Belaustegui warns about low metabolic flexibility and how the body switches to fat-burning mode, as reported by La Vanguardia.
Metabolic flexibility explained
Nutritionist Isabel Belaustegui discusses the concept of metabolic flexibility on the podcast A lo grande, explaining how the body can switch between burning glucose and fat for energy. She highlights that poor metabolic flexibility may prevent the body from efficiently using fat as fuel.Signs of low metabolic flexibility
Belaustegui notes that people who feel hungry when they wake up, need to eat every three hours, or struggle to lose stubborn fat around the waist may have low metabolic flexibility. This means their bodies remain in a sugar-burning mode rather than switching to fat-burning.How the body switches energy sources
According to Belaustegui, the body uses glucose from carbohydrate-rich foods like bread, pasta, cookies, and vegetables for energy. However, during fasting or when consuming fat-rich foods, the metabolism shifts to using fat as the primary energy source.Foods to improve metabolic flexibility
Belaustegui suggests incorporating foods like avocado, coconut oil, and extra virgin olive oil into the diet. These fats provide sustained energy, reduce meal frequency, and help maintain fasting without causing hunger. More information is available on the website Doctissimo.
