Energy metabolism is one of the basic topics of nutrition that is often misunderstood and misinterpreted. Danny Lennon, MSc. in Nutritional Science, explains energy needs and importance of carbohydrates for athletes and then we dive into fat adaptation, fasted exercise and recovery. Danny then explains chrononutrition and how it affects our health.

Chrononutrition:

  • Circadian misalignment is typical among shift-workers.
  • Internal circadian rhythms play a large role in physiology and overall health.
  • Lifestyle (eating and sleeping pattern) can promote or disrupt circadian rhythms.
  • Disrupted circadian rhythms compromise health and increase the risk of disease.
  • We response differently to food based on the time of the day we eat it.
  • Our insulin sensitivity is higher in the morning hours.
  • Symptoms of circadian misalignment can be similar to a jet-lag.
