Intermittent Fasting Expert Explains Why Skipping Breakfast Fails
Lo ideal sería consumir el primer alimento cuando está saliendo el sol y antes de que caiga la noche hacer la última comida del día,
says Diana Díaz-Rizzolo, a researcher at Columbia University and professor at the Universitat Oberta de Catalunya.
Intermittent fasting has surged as a popular alternative to traditional eating patterns of three to five daily meals, yet widespread confusion persists regarding its fundamental biological principles, according to reporting by Álvaro Piqueras published on Men’s Health and Runner’s World. Piqueras holds a degree in Advertising and Public Relations from the University of Alicante, and also possesses specific training in social media management and direction, strategic planning, and graphic design. He began his career in local and regional media outlets in the land of Don Quixote, specifically in Albacete. From there, he pursued his dream of working for some of the country’s main publishing groups, such as Prisa, Vocento, and now also Hearst.
Key Clinical Takeaways:
- Intermittent fasting encompasses time-restricted feeding, alternate-day fasting, and whole-day fasting methods like the 5:2 diet.
- Human biological clocks in the hypothalamus align metabolic processes with daylight through cortisol production while shifting to cellular recycling and night-time cleansing under melatonin release.
- Many practitioners mistakenly skip breakfast rather than dinner, conflicting directly with circadian rhythms.
Three Primary Fasting Patterns Dominate Current Nutritional Trends
The practice generally involves alternating eating windows with regular fasting periods. Three primary patterns dominate current nutritional trends: time-restricted feeding—exemplified by the 16:8 protocol involving 16 hours of fasting and an 8-hour eating window—alongside alternate-day fasting and whole-day fasting regimens.
Despite the popularity of time-restricted feeding with fasting windows spanning 12 to 16 hours, implementation often directly opposes internal circadian biology. The human internal clock resides within the hypothalamus in the brain. Retinal light absorption signals daytime hours, prompting cortisol production to elevate in the morning, which initiates wakefulness and metabolic processes such as nutrient digestion.
Hormonal Shifts Halt Digestive Processes as Daylight Fades
As daylight fades, cortisol levels drop and melatonin rises. This hormonal shift halts digestive processes to initiate cellular cleanup and metabolic recycling.
Por la noche no solo descansamos, estamos trabajando a tope, pero de en otras cosas muy distintas a las que hacemos durante el día, que es el reciclaje, que es la limpieza, que es la depuración. Y para que eso ocurra tenemos que estar en una situación de ayuno, pero en un ayuno nocturno,
Díaz-Rizzolo explains regarding the necessity of nighttime fasting.
Counter to this internal biological logic, individuals frequently execute fasts incorrectly by skipping morning meals. When asked about their fasting habits, individuals consistently choose to omit breakfast rather than dinner.
